STANDARD Physics Work-Energy Theorem MCQ Question
Identify the false statement from the following.
Work-energy theorem is not independent of Newton's second law.
Work-energy theorem holds in all inertial frames.
Work done by friction over a closed path is zero.
Work done is a scalar quantity.
Correct Answer
Detailed Explanation
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. While all other statements are correct.
