PHY 101 Work, Energy and Power Objective Question
Take CBT

Question

For a non-conservative force, which statement is true?
Options
A The work done depends only on the initial and final positions.
B Potential energy can be defined for it.
C The work done depends on the path taken by the object.
Correct Answer
D The work done around a closed path is always zero.
Correct Answer

Option C is the correct answer.

Detailed Explanation

A force is nonconservative if the work it does on an object depends on the path taken by the object between its final and starting points. Potential energy cannot be defined for such forces.

Hint

Friction does more work on a longer path than a shorter one.
