Question

Sliding friction is greater than .................. friction.

Answer 1

1. Sliding friction is a type of friction that acts between two surfaces when the object is already in motion or one object is sliding over the other object.
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. As we know friction is caused by the interlocking of the irregularities which are present on the surface.
5. Since interlocking of irregularities is less in rolling friction, therefore, rolling friction is less than static friction.

Hence the right answer is: Sliding friction is greater than rolling friction.
