the resistance to motion experienced when rolling an object is called rolling friction . it is less than sliding friction (frictional force offered when sliding an object ) . it is very useful and used in the following ways :– 1. in ball bearings to reduce friction by converting sliding into rolling friction.
When an object rolls over the surface of another object , the resistance to its motion is called rolling friction.
