Question

explain about variations of Friction with example​

Answer 1

Explanation:

Friction is a type of force which caused due to roughness of a suface.It depends on how rough is a surface.If more the roughness then higher the friction and vice versa.

For example:

A glass ball has less friction compared to a rubber ball.Because glass ball has smooth surface,therefore less friction.

There are two type of friction:

1)Static friction(for a body at rest)

2)Kinetic friction(for a moving body)
