Question

Hello everyone
Define rolling friction force .​

Answer 1

hello , :-)

Rolling friction occurs when a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings. The main source of friction in rolling appears to be dissipation of energy involved in deformation of the objects.

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation of the wheel, roadbed, etc., is recovered when the pressure is removed. 

Answer 2

Answer:

The force resisting the motion of a rolling body on a surface is known as rolling friction or rolling resistance.Rolling of ball or wheel on the ground is an example of Rolling friction. The other type of friction is slidingfriction.
