Question

explain why rolling friction is less than sliding friction​

Answer 1

Answer:

The force of friction depends on the area of contact between the two surfaces. As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction. ... It is much less than sliding friction for the same pair of bodies

Answer 2

Explanation:

Sliding friction is the force resisting the motion when a body slides on a surface. The force of friction depends on the area of contact between the two surfaces. As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction.
