NEET Physics Work-Energy Theorem MCQ Question
Which of the following statements about the Work-Energy Theorem is correct?
The work done by a conservative force depends only on the initial and final positions of an object.
The kinetic energy of an object at the bottom of a frictionless incline depends on the angle of inclination.
The Work-Energy Theorem applies only to constant forces acting on an object.
The total mechanical energy is conserved even when non-conservative forces perform work on the object.
Correct Answer
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.
