Utforska lutande plan i förskolan
Barnen har redan flera olika erfarenheter av lutande plan och friktion. Lyssna till barnen under leken och ta reda på vad som intresserar dem, vilka strategier de använder och vilka erfarenheter de har.
När barn och vuxna utforskar tillsammans finns förutsättningar att göra spontana situationer till mer systematiska undersökningar kring friktion och grad av lutning. Här hittar du förslag på hur lek och planerade situationer kan organiseras. Det finns också frågor som kan bidra till diskussioner och reflektioner kring barns möjligheter att lära och utvecklas inom naturvetenskap och teknik.
Film: Lutande planet (tid 02:06 min.)
I filmen syns först två yngre förskolebarn som rullar bollar upp och ner för en rutschkana inomhus. Den andra delen av filmen visar två barn som undersöker en träplanka som fungerar som ett lutande plan med kulor och bilar. I den tredje delen av filmen befinner sig ett flertal barn utomhus och utforskar lutande plan på förskolans gård med hjul och rockringar.
Utforska lutande plan i vardagen
På vilka olika sätt kan sådana tillfällen som de vi ser i filmen, användas av förskollärare och arbetslag så att barnen får möjlighet att vidga sina erfarenheter kring lutande plan?
Utmana och stimulera barnens utforskande genom att pröva och visa
- hur vissa föremål rullar och andra glider ner för det lutande planet
- hur ytan på det lutande planet och ytan på det föremål som glider (och/eller rullar) ner för planet påverkas av friktionen som uppstår
- hur olika ytor påverkar föremålens möjlighet att glida ner för det lutande planet
- hur planets lutning påverkar föremålets hastighet. Förändra lutningen på planet och undersök vad som sker med föremålen. Jämför mellan olika föremål.
I utforskandet upptäcker barnen att vissa föremål rullar och andra glider ner för lutande plan. I utforskandet har de också möjlighet att studera föremålens utformning, storlek, underlag och att det kan ha betydelse för hastigheten om föremålet glider eller rullar (friktion).
I de här aktiviteterna får barnen undersöka olika föremåls ytor och vilken friktion som uppstår. De får också undersöka vilken lutning planet har och kan se att lutningen påverkar hur de olika föremålen rullar och glider.
Friktion uppkommer när två ojämna ytor gnider mot varandra. Genom att ytorna hakar i varandra försvåras rörelsen. Ibland vill vi ha låg friktion, till exempel för att glida snabbt på våra skridskor. Ibland vill vi ha hög friktion, till exempel på vinterskorna så att vi inte halkar, eller när vi startar och bromsar på cykeln. Då vill vi inte glida iväg på däcken.
I det naturvetenskapliga arbetssättet ingår ofta att förändra en faktor (ibland kallat variabel) i taget så att man efteråt vet mera exakt vad det var som orsakade en förändring. Sådana systematiska undersökningar kan ofta göras av barn och vuxna tillsammans. När det gäller lutande plan och olika föremåls rörelse finns det många sätt att arbeta på, både i spontan lek och i mera organiserade aktiviteter. För att göra det möjligt att urskilja till exempel vilken påverkan friktion har på föremålet när det rör sig nerför det lutande planet kan du stötta barnen att inte förändra mer än en variabel i taget när de gör sina undersökningar.
Film: Lutande planet – intervjuer (tid 02:18 min.)
I filmen nedan reflekterar förskollärare kring barnens utforskande och lärande inom området lutande plan.
Diskussion och reflektion
Utgå från filmen och diskutera:.
- Vad i filmen känner ni igen från er egen praktik?
- Vad i filmen fångade er som förskollärare och arbetslag? Hur kan ni gå vidare för att utveckla er undervisning med filmens innehåll som utgångspunkt?
Utgå från er egen praktik, diskutera och reflektera:
- I vilka spontana och planerade aktiviteter får barnen möjlighet att undersöka lutande plan och friktion tillsammans med er och tillsammans med och andra barn?
- I vilka miljöer och vid vilka tillfällen får barnen möjlighet att undersöka lutande plan och friktion tillsammans med er och tillsammans med och andra barn?
- Erbjuds barnen att undersöka friktion systematiskt och att formulera och prova egna och andras hypoteser?
- På vilka sätt kan ni som förskollärare och arbetslag utmana, stimulera och stötta barnen till ett fortsatt undersökande och lärande om lutande plan och friktion?
Här finns fler exempel på hur du kan utforska lutande plan och friktion tillsammans med barnen.
Friktion i vardagen
I förskolan och förskoleklassen finns många möjligheter att arbeta med friktion och lutande plan. Förskollärare och arbetslag kan stötta barnen i att uppleva, uppmärksamma, samtala och urskilja friktion genom att utgå från barnens egna lekar, deras omgivning och dagliga situationer.
Fundera kring hur det som sker i förskolan kan leda vidare till att utforska lutande plan och friktion på andra platser i omgivningen? Hur kan förskollärare och arbetslag göra det möjligt för barnen att vidga sina erfarenheter av dessa fysikaliska fenomen?
Använd olika ytor inomhus
Gör det möjligt för barnen att, i spontana och planerade aktiviteter, tillsammans undersöka olika ytor inomhus:
- Låt dem åka kana med fötterna på ett golv och jämföra skillnaden mellan att vara barfota, ha sock-i-plast, bomullsstrumpor, mockasiner och skinnskor med gummisula eller skinnsula. Vilka likheter och skillnader finns i dessa upplevelser?
- Låt dem prova att dra varandra över golvet sittandes på olika tygstycken som bomullstyg, sammetstyg eller nylontyger. Vilka likheter och skillnader upplever den som drar respektive den som åker med?
- Låt dem känna med handen på olika ytor som finns runt om i förskolan. Hur känns de? Kanske är ytan slät, skrovlig, vass eller hal. Koppla samman detta med barns funderingar kring vad som skulle vara ett bra underlag om man vill få en kloss att glida, eller vilket underlag som krävs för att kunna ta sig upp för en brant lutning.
Använd olika ytor utomhus
Låt barnen undersöka och utforska olika ytor utomhus genom att de får gå på olika underlag som asfalt, grus, is och snö med stövlar och skor som har olika slags sulor.
Med de äldre barnen kan man tala om de olika förutsättningar som finns under olika årstider. Fundera över om det kan finnas situationer då det är halt på sommaren, hösten eller vintern. När är det bäst att åka kana i en backe? När går det bäst att gå upp för en brant backe?
Utforska lutande plan och friktion
Låt barnen undersöka friktion och lutande plan tillsammans med vuxna genom att åka rutschkana med olika kläder och jämföra dessa, exempelvis genom att åka med tunna bomullsbyxor, joggingbyxor, galonbyxor, barbent och så vidare.
Förändra och påverka friktion som uppstår mellan olika ytor
Gör det möjligt för barnen att påverka den friktion som uppstår emellan olika ytor genom att laborera med olika vätskor och material. Jämför mellan att
- föra handflatorna emot varandra med och utan tvål på händerna
- dra en pulka på snö och dra en pulka i grus
- gå på en isfläck och sedan hälla sand på den och prova att gå ytterligare en gång
- trampa runt på en cykel och sedan smörja dess nav med olja
- dra med handen emot en torr respektive en våt bordsskiva.
När barnen utforskar friktion i sin omgivning uppmuntras de att undersöka och uppleva omvärlden med nya perspektiv och se på vardagens aktiviteter ur en naturvetenskaplig vinkel. När de känner på släta, skrovliga, vassa och hala ytor (med eller utan) tvål på händerna, eller åker kana, får de möjlighet att använda känselsinnet och erövrar kunskap genom kroppslig erfarenhet.
Att kunna förändra och påverka friktion är också viktigt kunskap för barn. Exempel på detta är att gå på en isfläck och sedan hälla sand på den. Genom att barn och vuxna undersöker friktion tillsammans i vardagen sätts det naturvetenskapliga fenomenet friktion in i ett naturligt och meningsfullt sammanhang.
Lutande plan och friktion
Att göra systematiska undersökningar och att stötta barn i att formulera och testa egna och andras hypoteser är ett sätt att fortsätta utforska lutande plan och friktion.
Systematiska undersökningar
När man vill undersöka något mer systematiskt är det centralt att ha något som är konstant och något som varierar. Det vill säga, om det är friktion som du vill att barnen ska kunna urskilja och rikta sin uppmärksamhet emot, behöver graden av lutning på planet vara konstant och föremålen som glider variera.
Utgå från ett lutande plan, till exempel en backe i naturen eller en lutande planka, och låt barnen tillsammans med vuxna undersöka hur olika föremål som bollar, bilar, hjul och kulor med olika storlek och tyngd rullar. Samtala om
- vilka föremål som rullar sakta respektive fort
- varför vissa föremål rullar fortare än andra
- varför vissa föremål inte rullar alls
- hur vi kan påverka på vilket sätt som föremålen rullar.
Låt barnen, tillsammans med vuxna, undersöka hur hjul med lika storlek rullar ner för en lutning som har olika ytor, exempelvis asfalt, gräs, löv, grus, is, jord, sand.Undersök hur olika föremål som is, klossar, stenar etcetera kan glida på eller nerför ytor som golv, asfalt, gräsmatta, grus och sand.
Genom att ställa hypoteser och genomföra systematiska undersökningar kan både barn och vuxna medvetet studera det som hålls konstant och det som tillåts variera. Man kan då samtala om sina iakttagelser och barnens uppfattningar kan göras till innehåll för fortsatt undersökande. Att på olika sätt dokumentera händelseförloppen gör också att barn och vuxna tillsammans kan studera vad som händer vid undersökningarna. På det sättet blir barnen delaktiga i hela processen.

Planeringar
Tegelbrukets förskola, Svedala · Senast uppdaterad: 28 augusti 2020
Vi vill väcka barnens intressen för det naturvetenskapliga fenomenet friktion på ett lustfyllt och utforskande sätt tillsammans.
Upprättat den 14/9 av Bullerbyn
Läroplansmål:
Förskolan ska sträva efter att varje barn utvecklar sin förmåga att urskilja, utforska, dokumentera, ställa frågor om och samtala om naturvetenskap
Kärnämne: Koncentration
Var är vi? (Nuläge/syfte)
Dokumentationen av undersökningsperioden har visat att fenomenet friktion har blivit det vi ska fortsätta med som projekt med barnen.
Barnen har i den fria leken undersökt friktion med olika material.
Hur gör vi? (Planera/genomför/dokumentation/reflektion)
Vi väljer att arbeta med fenomenet Friktion.
5 aktiviteter som hör ihop med fenomenet:
Prylracet : barnen får titta på den korta filmen ”Prylracet”, där Tiggy undersöker friktion.. Detta blir en introduktion till fenomenet. Barnen får sedan prova samma experiment som de gjorde i filmen. De får prova att släppa olika föremål längst en ramp/skiva, för att se vilka som kommer ner först. Här belyser vi att friktion gör att olika föremål färdas i olika hastigheter beroende på vilket material den är tillverkad av.
Rutschkanan : Barnen får åka nerför rutschkanan på olika underlag/kläder. Vi provar även att lägga vatten och sand när de ska åka. Här får barnen känna med hela kroppen hur friktion påverkar hastigheten. De får uppleva när det går trögt eller fort. Detta blir samma som prylracet, fast med kroppen istället, och då får de en variation.
Olika material under fötterna: Barnen får stå på olika material och undersöka vilka som är lättast att kasa med. Detta har vi sett barnen göra i den fria leken och nu vill vi ge dem en förståelse för vad de gör. Vi pratar om att det kan uppstå hög eller låg friktion mellan materialen.
Skjutsa iväg föremål : Barnen får skjutsa iväg olika föremål längst golvet på olika underlag. Här fortsätter vi med samma experiment som innan , fast på ett annorlunda tillvägagångssätt. Barnen får leta upp material med hög och låg friktion. De får gissa om det är hög eller låg och sedan prova och se om de hade rätt.
Gnugga händerna: Barnen får prova att gnugga händerna mot varandra med olika material som vatten, lim, tvål och sand. Här vill vi att barnen ska använda sig av begreppen hög eller låg friktion.
Vi väljer att börja med en upplevelse med hela gruppen för att väcka barnens intresse och introducera fenomenet friktion. Yngre barn behöver uppleva med hela kroppen, därför är alla våra aktiviteter utformade så att kroppen är i fokus. Barnen får testa och uppleva samma sak fast på olika tillvägagångsätt. Vi vill att barnen ska få observera, testa själva, prata om och ställa enkla hypoteser om ämnet. Vi kommer att arbeta både helgrupp , men framförallt i små grupper med 3-4 barn i varje grupp.
Vi kommer tillföra material i våra lärmiljöer där barnen kan utforska fenomenet på egen hand.
På vägen lyssnar vi in barnen och deras intresse, frågor och hypoteser och utforskar tillsammans.
Vi dokumenterar med hjälp av foto, film och observerar barnens hypoteser. Alla barn ska få minst ett inlägg i sin lärlogg på unikum.

Easy Friction Tray – Friction Slide
March 8, 2022 By Emma Vanstone Leave a Comment
Friction is one of my favourite science concepts to learn about! It’s easy to investigate in many different ways with fun hands-on experiments and investigations.
Friction is created when objects are pulled past each other. Imagine pushing a box of books along a carpet and a wooden floor. It would be much easier to push the box along a wooden floor as the smooth surface means there’s less friction between the objects.
Let’s experiment with friction
We’ve made friction ramps before, but this version is so easy I wanted to share it as well.
You’ll need
A medium size tray
Small toy figure
Bubble wrap
Books ( to raise the tray )
Instructions
Divide the tray into three lengthways and choose two different surfaces to test. The third surface will be the smooth inside of the tray.
Place five books under the tray and check the toy figure slides down the ramp without a push. If it doesn’t, add a few extra books.
Place the toy at the top of the ramp and time how long it takes to reach the bottom on each surface.
If you want extra reliable results, repeat each slide three times and find the average time for each.
Remove a book and try again.
Keep going until the toy no longer slides down the ramp.
The bubble wrap is the roughest surface in our tray, so this is the slide with the most friction between the toy and the ramp. The bubble wrap slide was the slowest.
The fastest slide was the inside of the tray which is smooth. Therefore little friction is created as the toy slides down the ramp.
The science investigation below is slightly different but on the same theme. Simply print and follow the easy instructions!
Is friction helpful?
Sometimes! Thanks to friction, objects can start and stop moving. Friction also prevents objects from slipping around. We would probably fall over more if it wasn’t for friction.
Imagine trying to ride a bike on an ice rink and then on a pavement. Ice is a smooth surface, so there’s not much friction, which is why it’s slippy. The pavement is not smooth, so there’s more friction between the bike tyres and the pavement making it much easier to ride a bike on. Without friction riding a bike on any surface would be like riding on ice!
However, friction also leads to some energy waste, as it’s a force that must be overcome. Often heat is produced when energy is transferred between objects which also wastes some energy. Oil is used on bike chains and in the moving bits of a car engine to reduce friction between parts and reduce the amount of heat produced.
Friction always slows an object down, so it’s helpful if you want to keep something moving!
Friction Facts
Friction is a force, we can’t see it, but we can see its effect.
Friction acts in the opposite direction of the object moving!
There’s more friction between two rough objects than between two smooth objects.
Liquids also experience friction; the more friction between liquid layers, the more viscous ( thick ) the liquid is.
Take a look at my full size friction ramp and find lots more ideas for investigations and experiments for learning about friction !

Exploring Friction: Hands-on Friction Activities for Kids
Science is one of those things best-taught hands-on so children can really get a grasp for what they are learning. Two great concepts to teach your child hands-on are Exploring force and friction.
Putting these together to create a day of fun and learning is a great way to keep the kids busy. This simple Science Experiment Exploring Friction is fun and creates are when you are done.
This simple Science Experiment Exploring Friction
This one was pretty easy and a great way for the older kids to get a “feel” for friction. As the ball slides you can feel it slip when covered in paint. All you need is:
We decided to go with the primary colors so the kids could watch them mix and blend as the balls rolled back and forth. I taped the paper down to the tray on the underside to keep everything where I wanted it as the tray flopped every which way. That was a good choice on my part.
At one point the kids got a little carried away and bouncy balls went everywhere leaving children and the yard painted. The giggles involved were worth the mess and as you all know Baby Bear did not mind one bit. She had already covered herself in marker.
This Exploring Friction art project was so much fun and the end result was pretty cool.
Exploring friction with kids.
Teaching kids about friction can be a lot of fun when you incorporate hands-on activities and experiments. Here are some engaging ideas to help kids understand the concept of friction:
Sliding and Rolling Races: Have kids race different objects down a ramp or slide to show how different materials and shapes are affected by friction. Use a variety of items such as a toy car, a ball, and a block. Ask them to predict which will reach the bottom first and why. After the race, discuss the role of friction in the results.
Rug vs. Tile Experiment: Have your child push a toy car or slide a book on different surfaces (like a rug and a tile floor). Ask them why it’s easier to move on one surface than the other. This can help them understand that smoother surfaces produce less friction.
Shoe Experiment: Have your kids try walking or running with different types of shoes (sneakers, flip flops, socks, or barefoot) on various surfaces (grass, pavement, carpet, etc.). Discuss how different materials and surfaces create more or less friction.
Sandbox Friction: If you have access to a sandbox, bury a few objects and have your child try to pull them out. Discuss how the sand creates friction, making it harder to pull the items out.
Ice Skating: If possible, go ice skating. Ice creates less friction than many surfaces, which is why it’s slippery. It’s a great way to demonstrate how reduced friction affects movement.
Craft Stick Friction: Take two craft sticks and try to slide them against each other. Then, wet the sticks and try again. Discuss why it’s harder to slide the wet sticks, as the water increases the friction between them.
Balloon Experiment: Rub a balloon on different materials (like a wool sweater or your hair). The friction creates static electricity, causing the balloon to stick to these surfaces.
Brake Pad Experiment: Use two pieces of sandpaper to simulate car brake pads. Have your child press and slide the pieces together, feeling the heat generated from the friction.
Remember, when teaching kids about scientific concepts like friction, it’s important to let them explore, observe, and make predictions. This helps them develop critical thinking skills and a better understanding of the science behind everyday phenomena.

This is such a great idea. Children always learn best when it’s fun, involving, and visual. I love it!
That would be fun! It looks like some fancy modern Art too. My son and I would love to do that stuff.
Yes, yes, yes! This is awesome. My boys LOVE to do STEM projects like this!!!
That looks like a lot of fun. I would love to do this with my girls. I know that they would just love it.
This looks like so much fun. My kids would love to do a project like this to explore what friction is all about.
This is a great way to explore friction. I will have to do this experiment with my kids this weekend.
What a great way to make science accessible and dare I say it FUN for kids! Great activity for a rainy day or a homeschool family!
This is a really great idea. Fun and educational for the kids. I need to do this with mine.
That marble art is really cool! I want to try that with my three kids.
This is such a great way to teach children. With a lot of kids being visual learners – this is defiantly a great way to help them learn.
So fun! I love that learning doesn’t stop when the school bell rings. Kids love to learn through hands-on experimentation and exploration.
This is so cool. My kids love doing science projects like this.
How much fun! We are homeschoolers and are going to try this. I’m always looking for fun ways to teach.
This is a great way to explore friction. I will have to do this experiment with my nieces!
The experiment resulted in a pretty piece of art too! I really like this kind of learning.
I love learning about fun kids activities that combine the arts with science. Your kids study of friction is just brilliant.
This is a cool way to get kids interested in the practical applications of science. Awesome.
Wow that is a nice piece of art!My nephews would have a ball with this and I would too watching them and chilling!

Simple Friction Experiments for kids
Today, I taught 3-6 year olds about friction! I love taking fundamental science topics and teaching them to young kids in a way that they can understand and learn from. There are lots of experiments for kids that you can try and this one worked so well that I wanted to share it with you.
To me, kindergarten is all about kids being introduced to as many things and ideas as possible.
I find that science experiments for kids, especially when they are hands-on, help them gain an understanding of the world around them.
This experiment required a little bit of prep, but it was easy and fairly quick.
If you have children who are interested or asking questions related to friction, this experiment for kids is a great place to start for kids at any age.
Our activity today involved a bunch of old wooden blocks covered with different materials and a ramp! To cover each of the blocks with a different material, you will need:
- Small Wooden Blocks
- Foam (I used part of an old drawer insert/ bath mat)
- Electrical Tape
- Packing Tape
- Plastic Wrap
- Bubble Wrap
- Aluminum Foil
- Cotton Batting
- Construction Paper
- Parchment Paper
- Mesh Material
- Long Piece of Wood to Create a Ramp
- Large Plastic Towel Clips and Thin Piece of Wood (Optional – These are to create sides on the ramp).
Prepare each block by gluing or sticking a different material to it. You don’t need to use the same materials as I did. I simply walked around my house and used materials that I had on hand.
The important thing about the materials that you choose is selecting a variety of materials. Make sure that some are slippery and others are not.
Since I was working with a large group of children, I made duplicates of each block. So I had two blocks covered with a piece of silk and two covered with felt etc.
Once the materials have all dried onto the blocks, you are ready to do your experiment.
The Experiment
I started by showing the children the blocks. Next, I passed them around and had children feel the different materials. I asked them what they noticed and asked them to describe what they felt.
Children noticed right away that each of the blocks felt different. They noticed that some were “soft” and others were “flat”. It is important to give children time to take note that the blocks are different. But will it make a difference?
Next, I gave small groups of children a long piece of wood to create a ramp. They attached 2 sticks to the sides with large towel pins. These acted as bumpers so that the blocks wouldn’t fall off.
You don’t need to create bumpers at the sides, but it does help to keep the blocks on the ramp when sliding the blocks down the ramp. You could also use a plastic slide to do this experiment.
Next, children guessed which blocks would go down the ramp the fastest and why. Would something smooth cause a fast slide? What about the felt? Everyone made a prediction before we started.
Children started by choosing a few different blocks. They set one at the top of the ramp and then let go. Children quickly discovered that not all of the blocks slid down the ramp. Some didn’t move at all!
Children experimented over and over and let the blocks slide down their ramp and watched how the different coverings affected how the block slid. They noticed that the material the block was covered with was making a difference in how it slid.
Was the block fast or slow? Did it even make it to the bottom? What similarity did you notice about the materials going fast?
Children then started to notice which types of materials caused the blocks to slide the fastest. The smooth blocks slid fast and far!
They then started racing blocks by letting two go at once at the top.
I introduced the word friction to children when they told me that the tape covered block went faster than the felt. We talked about the fact that the tape created less friction so it moved faster.
Once everyone was done, we discussed which blocks slid best and what these blocks all had in common. Children commented that the smooth blocks were all the fastest.
I explained that because it was smooth, there was less friction between it and the ramp. Therefore, it goes down without being slowed.
To continue this idea I asked children what would happen if their slide in the playground was made of carpet instead of plastic? They knew that this would not be a good material for a slide, because they would get stuck at the top.
This allowed them to relate their experiment to their real world and understand that materials each have different qualities and characteristics.
It is not important for children at a young age to understand the technicalities of friction. What this experiment for kids does show is that materials are different and depending on the characteristics of the material they behave differently.
Children begin to notice the way different materials feel different. They begin to notice that their world is filled with different materials and each of these materials serve a purpose.
Sometimes you want to create friction, other times you want to avoid it. There is a material for each.
I am always amazed at how much learning happens with experiments for kids like this. Later in the day children were playing, but also experimenting again, by sliding different things down the playground slide.
They noticed that a pebble slid faster then their mitten because there was less friction with the pebble. The experiment we did together helped them to understand their world and things they play with on a daily basis.
I love the fact that this experiment for kids is hands-on and play based. Children learn as they play and experiment.

The topic of friction can be a little dry. Consider lubricating students' interest with these two examples
Friction around Pole
What it shows : Many people have probably observed that, by wrapping a rope around a post, a person can hold in check a much larger force than would ordinarily be possible. In this experiment a flexible thick rope is wound around a horizontal pipe. Due to the interaction of the frictional forces and tension, there can be a considerable difference in tension between the two ends of the rope. In the demonstration, one end of the rope supports a (heavy) load and the other end is held by (small) "holding" force. The demonstration models the principle by which a capstan works.
How it works : The Euler-Eytelwein equation (1) relates the tension of the two ends of the rope: T 2 = T 1 e μθ , where T 2 is the tension in the rope due to the load it's supporting, T 1 is the tension necessary to hold the load without slipping, μ is the coefficient of friction between the rope and the pipe, and θ is the total angle (measured in radians) made by all the windings of the rope (one full winding is 2∏ radians). The tension force increases exponentially with the coefficient of friction and the number of turns around the pipe. Note that the diameter of the pipe does not come into play. However, the pipe diameter cannot be too small because a significant amount of force would be lost in bending the rope around the pipe, especially if the rope is a little stiff.
Setting it up : Secure a 2"-diameter steel pipe to the edge of the lecture bench with two C-clamps, as shown in the photographs. Use the 3/8"-diameter nylon rope. Our 65-lb wrecking ball makes an impressive heavy load. Tie one end of the rope to the ball and wrap several turns of the rope around the pipe. Upon slowly unwrapping the rope, you'll discover that 4½ turns is enough to hold the ball with only the weight of the loose rope supplying the "holding" force. That length of loose rope weighs about 0.11 lb. With θ=9∏, this suggests that μ≈0.23 (not an unreasonable number). With 2½ turns you can easily hold the ball with just your fingers. The 3rd photo shows a 100-lb dumbbell held with just 4½ turns of rope and the fingers supplying the tension. Using μ≈0.23, we estimate a 0.15 lb finger holding force.
Comments : Exponential relationships are always astounding and this is no exception. Many devices based on belt or wrap friction are used in rappelling, rock climbing (so-called top-roping in which one can hold (belay) a heavy person to prevent a fall), sailing, and rigging of equipment. The ubiquitus V-belt and pulley is another example, cleverly enhanced by the V shape. The relation between tightside and slackside tension for a V-belt is similar:
T 2 = T 1 e μθ/sin(β/2) , where β is the angle of the V in the pulley (note that for β=180 degrees, we are back to the flat belt relationship).

Please see my disclosure policy for more details. Someone recently told me about this friction science experiment . We’re huge fans of science activities in our home. I knew I had to try it out and add it to my arsenal of easy science experiments ! As for this friction experiment, I listened to the explanation but doubted if the “experiment” would work. So, like any good parent and educator, I tested it out. First by myself and then with my children. The age range of my children is five years, so I always have to think about how to approach science activities in age-appropriate ways. This activity is suited for a preschooler but is also great to add to your bucket of science experiments for 5th graders! I like that range! Also, add it to your list of science fair projects to wow peers and teachers!  I like to do activities by myself first, not because I don’t want to fail in front of kids (that is a healthy and great thing for children to observe), but because I want to be organized with the materials. I want to discuss the concept and the experiment without stumbling for a bag of rice. ;-) The post includes photos of my sons when we experimented. They were joyous, amazed with the result, and had loads of questions and ideas on what to do next with this experiment. This easy friction science experiment ignited their desire to learn more! Friction Science Experiment Idea Materials for Friction Experiment
 Steps to Friction Experiment
What is Friction?Friction is a force we experience every day, all day. We can’t see it. So, we tend not to notice it. Friction is the force that opposes the movement of one substance against another. In this case, we had rice and a chopstick. As the rice sits in the bottle, air pockets around most grains prevent friction. Live Science tells us, “It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.” (Source: LiveScience )  History of FrictionSo when did we first discover this tremendous force? Believe it or not, scientists began identifying and understanding the laws governing friction in the 1400s! The cool part about friction is that the interactions are so complex that many experiments in various situations (different materials, etc.) have to happen to understand the concept truly. Unlike other forces, friction can’t be derived from equations or laws alone. I learned from LiveScience that there are exceptions to the rules of friction: “…while two rough surfaces (such as sandpaper) rubbing against each other sometimes have more friction, very smoothly polished materials (such as plates of glass) that have been carefully cleaned of all surface particles may stick to each other very strongly.” How interesting is that??? Science Behind Friction ExperimentsAs we push the chopstick into the bottle, the grains of rice settle close to one another, eliminating most of the air pockets. Once this happens, the frictional force overwhelms the rice, and so the rice will push against the chopstick. The grains are pushing so forcefully they create a force that causes the chopstick to become stuck, enabling you to pick up the bottle of rice.

Since the spring of 2018, VibroBox has also established strong connections with SKF Moscow office (LLC SKF, Moscow). During the period from 6th of April till 7th of June 2018, SKF team tested VibroBox system for automatic assessment of the technical condition of industrial equipment. The primary goal of the experiment was the practical confirmation of the functionality, efficiency, and reliability of the VibroBox system. SKF provided diagnostic equipment and software for data collection during the tests. VibroBox Cloud Processing System analyzed vibration data, detected defects and issued recommendations on the technical condition of the equipment remotely from Minsk. VibroBox system achieved a very high detection rate of defects. Almost 100% of probing cases were correctly recognized. The only case in question was an unexpected manual bearing replacement (however, now VibroBox correctly processes similar cases). Most importantly, the VibroBox team was not present during the experiment in Moscow, all tests were performed by SKF team only. This emphasizes the objectivity of achieved results and confirms the high efficiency of the VibroBox solution. Having evaluated the test results, SKF named the VibroBox solution as promising. The companies outlined further actions to expand cooperation, including the implementation of joint commercial projects in Russia. The VibroBox team thanks colleagues from SKF for the trust and professional support of the project!  Siarhei Vasiukevich with SKF colleague.  SKF test equipment.  Results of experiment.

Friction around Pole What it shows : Many people have probably observed that, by wrapping a rope around a post, a person can hold in check a much larger force than would ordinarily be possible. In this experiment a flexible thick rope is wound around a horizontal pipe. Due to the interaction of the frictional forces and tension, there can be a considerable difference in tension between the two ...
