Question

compare sliding friction with rolling friction

Answer 1

Rolling friction is the resistance to motion experienced by a body when it rolls upon another. It is much less thansliding friction for same pair of bodies. When one body rolls upon another, there is theoretically no sliding or slip between them. And if both are perfectly rigid, there is no surface of contact.

Answer 2

♥ The force resisting the motion of a rolling body on a surface is known as rolling friction .

E.g - Rolling of ball or wheel on the ground .

♥ Sliding friction is the restriction on the body’s movement as only one side of the body is in contact with the surface .

E.g - Pushing a box across the table .
