Question

Interlocking is ______ in rolling friction.

Answer 1

1. Friction is a contact force that acts between two surfaces when there is a relative motion between them.
2. Rolling friction: It is a type of friction between two surfaces when one object is rolling over another object.
3. For example motion of a wheel on the road.
4. Due to less area in contact, the interlocking of irregularities is less in rolling friction, therefore, rolling friction is less than other types of friction.

Hence the right answer is: Interlocking is less in rolling friction.
