NEET Physics Work-Energy Theorem MCQ Question
Which of the following statements about the Work-Energy Theorem is correct?
The Work-Energy Theorem relates the change in kinetic energy to the work done by all forces.
The theorem states that work done is always positive regardless of the direction of force.
The Work-Energy Theorem applies only to conservative forces and not to non-conservative forces.
The theorem integrates the instantaneous force over time to determine work done.
Correct Answer
Detailed Explanation
The Work-Energy Theorem connects the change in kinetic energy to the work done by forces acting on an object, as indicated in the NCERT context. Option B misrepresents that work done can be negative, while option C incorrectly restricts the theorem to conservative forces. Option D incorrectly states that it integrates over time instead of position.
