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.
An object undergoing rolling motion doesn’t have any friction between the wheel and the ground. The reason for this is that conceptionally there is no motion between the point where the wheel and the ground touch; each instant in time produces this motionless result. So when an object goes from sliding to rolling, the friction on the surface becomes negligeable.
Friction arises due to the surfaces not being perfectly flat, so, if there was a residual effect of the rough surface, it may affect the direction or speed of the motion, as a wheel is disrupted on a bumpy road.
