Question

Why sliding friction is less than rolling 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. Rolling friction is the resistance to motion experienced by a body when it rolls upon another.

Answer 2

Explanation:

sliding friction works on large are

while in rolling the area is less so friction is less
