What are two examples of friction?

Answer 1

Say you are driving a car or riding a motorcycle and you just remove you foot or hand from the accelerator. What will happen? After some time depending on your velocity, the vehicle will stop. Why? Consider your entire vehicle an ideal system meaning that no part provides any sort of friction. Now consider road, road is rough and will definitely provide friction. Since your vehicle's tires are rolling against the road, the road will provide friction in the direction opposite to that of your vehicle's motion. In real situations, both tire and road will contribute to the rolling friction.

Answer 2

Sliding friction is another name for kinetic friction and occurs between two objects that are in sliding contact. The motion of a piston in a cylinder has sliding friction between the two objects.

Answer 3

When you drag sandpaper across wood or slide down a slide.

Answer 4

An example of rolling friction would be like a skateboard rolling on a sidewalk.

Answer 5

A bike rolling down a hill. The bike's tires rub against the hill, creating friction, causing the bike to slow down and not keep rolling and rolling

Answer 6

When you put the brakes on your bike is friction. If you rub your hands together really fast, then you are also creating friction.

Answer 7

wheels of a bicycle

Answer 8
