(A) : It is easier to maintain the motion than to start it on rough surface .
(R) : Dynamic/kinetic friction is less than the force of limiting friction .

Why is it easier to maintain the motion than to state it?

It is easier to maintain the motion of a body than to start it. Why?

"The dynamic friction is a little less than the limiting friction ". Why ?

Coefficient of kinetic friction is less than

Explain why kinetic friction is less than static friction.

Static friction is more than kinetic friction.(Yes / No).

Why is sliding friction less than static friction?

(A) : If a body is trying to slip over a surface then friction acting on the body is necessarily equal to the limiting friction . (R) : Static friction can be less than the limiting friction force .

Why is force of limiting friction F_(c) greater than force of kinetic friction F_(k) .
