Question

Rolling friction is
(a) less than sliding friction
(b) more than sliding friction
(c) equal to sliding friction
(d) None of these.​

Answer 1

Answer:

option a ) less than sliding friction

Answer 2

Answer:

a) less than sliding friction

Explanation:

when an object is placed on the floor the the rough part of the object gets interlocked. when we slide an object the surface area in contact is more and during rolling the surface area is less so the friction is less.
