Work done by a frictional force is (a) Negative (b) positive (c) zero (d)all of the above

Answered by admin @ 17/08/2021

Answer:

Yes, work done by the kinetic friction on the object can be positive and also zero. Work done by the kinetic friction on an object is always the negative because the displacement is always opposite to the the frictional force.
