Physics-Work-Energy Theorem

NEET Physics Work-Energy Theorem MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following combinations correctly describes the Work-Energy Theorem?

A

The change in kinetic energy of a particle is equal to the work done by the net force acting on it.

B

The work done in a closed path by conservative forces is non-zero.

C

The total mechanical energy of a system is conserved only when non-conservative forces are present.

D

Potential energy does not convert to kinetic energy if the path taken by an object varies.

Correct Answer

Option A

Detailed Explanation

The Work-Energy Theorem states that the change in kinetic energy of a particle equals the work done on it by the net force, as mentioned in the NCERT context. Options B, C, and D misstate principles related to work done, conservative forces, and energy conservation.
