Question

What is rolling friction? Why do you think its value is lesser than static 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.
