NEET Physics Work-Energy Theorem MCQ Question
Which of the following statements about the Work-Energy Theorem is correct?
The change in kinetic energy equals the work done by the net force acting on a particle.
Work done is always positive and cannot be negative.
The work done by a net force is independent of the displacement of the particle.
The Work-Energy Theorem applies only to constant forces acting on a particle.
Correct Answer
Detailed Explanation
The Work-Energy Theorem states that the change in kinetic energy of a particle is equal to the work done on it by the net force, as mentioned in the NCERT context. The other statements reflect misconceptions about work being negative or the applicability of the theorem.
