Question

explain why rolling friction is more than sliding frication

Answer 1

Rolling friction is the resistance to motion experienced by a body when it rolls upon another. It is much less than sliding 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

hey buddy, its reason is that because in rolling friction the contact of the body with surface is less than as compare to sliding body,so more the area in contact more will be frictional force acting on the body which will oppose the body
