But what is it? ...The hardest part about friction...is getting started! Baadumtsss
Friction is a force that opposes motion. It is caused when two surfaces rub together and when they do this they produce heat.
Friction occurs when our shoes rub against the ground as we walk. It occurs when a bike's tyre rubs against the ground as you ride a bike. And it even occurs when your tongue rubs against as ice cream as you lick it. Yes, it's safe to say friction is happening all the time and without it, we would never be able to stop moving just like things that move through outer space.
Different surfaces have different frictional levels. Some surfaces have very high friction when rubbed together and stick together, while others have very low friction and are much more slippery. Professional mountain biker and best friend @kelangrant1353 explains the importance of friction when mountain biking while I demonstrate the perks of low friction while snowboarding!
Stay Tuned!
Friction occurs when Why is skating on an ice rink smoother? What is Friction? What is the frictional force?

The effort you put in your videos is fantastic! : )
Thank you so much 😊
Great job on your video :) You made it easy to learn challenging concepts.
Fantastic! Thanks a lot 👍
You sacrificed risking your life making this video wow
just wow
Teaching is a dangerous job 😂
Mild = push my luck, pull your leg
Spicy = Measure forces = midi-chlorians
Hot = What can forces do to an object = lift rocks and X-wings, throw boxes at family members, so you can distract them and cut off their hand.
Hahaha! Always thinking Out of the box 😂
Oh the irony of water making things slippery when it is actually a very sticky substance (molecular affinity and cohesion with water is super high).
Hey! So sorry for my late replies. It’s been a busy end of term 😮💨 That’s actually a good point 🤔
@@MrBradleyLearningMadeFun Just glad to hear you were not pulled into any war. Seems like many are.
Teaching friction, force and movement is fun in physics class, but in biology it suddenly keeps the same definitions but might well get you fired for saying the same things.
Yet another great video. Nice snowboarding skills by the way!
As for those bike tyres, talk about envy! My tyres tread is so thin you can see the air inside.
Hahaha! I’ll always make sure to go into the right classroom 😂
Thanks a lot! I have to say they aren’t anything compared to my mate biking skills though.
Well better overused than under used 💪🏻
Grass surface is high friction
Carpet surface is high friction
Mud surface is low friction, is slippery
Sand surface is very high friction
Wood floor is normal friction
Wetted floor is low friction, is slippery
Water surface is extremely high friction, that stops the object bouncing
Ice surface is lower friction, is slipperiest
Tarmac surface is low friction, is slippery
space surface has no friction and acts like zero gravity
and you cannot move while walking on the space surface
10 points to Gryffindor!
Yooo thanks man im way more careful from the ground i can finally use eletroc scooters,bikes,scooters,eletric bikes
You’re welcome! Sat careful out there 🤙🏻
