Question: Identify the false statement from the following:...
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 frication over a closed path is zero
D
Work done is a scalar quantity
Answer
Work done by frication over a closed path is zero
Explanation
Solution
Friction is a non-conservative force. Work done by a non-conservative force over a closed path is not zero.
Hence, option (3) is a false statement. While all other statements are correct.
