NEET Physics Work-Energy Theorem MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following statements about the Work-Energy Theorem is correct?

A

The work done by a conservative force depends only on the initial and final positions of an object.

B

The kinetic energy of an object at the bottom of a frictionless incline depends on the angle of inclination.

C

The Work-Energy Theorem applies only to constant forces acting on an object.

D

The total mechanical energy is conserved even when non-conservative forces perform work on the object.

Correct Answer

Option A

Detailed Explanation

The Work-Energy Theorem states that the work done by a conservative force, such as gravity, depends only on the initial and final positions, not on the path taken. This is emphasized in the NCERT context regarding conservative forces.
