Question

Q. Why rolling friction is less than sliding friction?

Give correct answer or else I report.

Answer 1

Answer:

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.

Hope it might be helpful to you

Answer 2

Sliding friction is greater than rolling friction because in sliding,the surfaces in contact have large area than that an rolling a wheel.
