Real Life Examples of Friction

Friction is the force that opposes motion between any surfaces that are in contact. There are at least four types of friction: static, sliding, rolling, and fluid friction. Static, sliding and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases

Static friction occurs when an object is resting on a surface. The static friction between the boots and the snow allows this person to stand and shovel snow.
When you rub your hands together you experience sliding friction.
When you ride a bike you depend on the rolling friction of the tires.
Sky diving depends on fluid friction between the air and the parachute to slow down.

In this video, I cover many real-life examples of friction and how friction helps you in everyday life.

*me watching this video cause my teacher sent it to me: 👁👄👁*

This might sound weird and specific, but I’ve been trying to find types of textures and surfaces that when i rub my finger against them, it causes it the skip across like vibrations. I’ve found that rubbery textures work like that but would there be any other things that can cause vibrations due to friction like that? The reason I’m asking is because I’m learning a method Called “drag clicking” which is based on vibrations due to dragging your finger across a surface.

Thanks bro help me do my homework a lot

I’m surprised he didn’t mention that friction generate static electricity.

friction may be internal and external.

i swear the entire comments is just "omg who is here from class omg im a kid omg omg"

"Fluid friction between the air, and *hopefully* the parachute opening"

Thank you this helped so much! I think ill do well on my test! 😃

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

This is a good video which told about friction
