Question

if there is no relative motion,frictional force _________




plzz give me answer fast​

Answer 1

Explanation:

If there is no relative motion between objects in contact, then the friction force (if there is one) is the static force of friction (FS). An example is a box that remains at rest on a ramp. The force of gravity acting down the ramp is opposed by a static force of friction acting up the ramp.

Answer 2

Answer:

if there is no relative motion, frictional force is more .
