Q. Identify the false statement from the following
A) Work-energy theorem is not independent of Newton’s second law
B) Work-energy theorem holds in all inertial frames
C) Work done by friction over a closed path is zero
D) No potential energy can be associated with friction
Explanation
(c) Friction is a non-conservative force. Work done by a non-conservative force over a closed path is not zero. Hence, option (c) is a false statement
