NEET Physics Work-Energy Theorem MCQ Question
Which of the following statements about the Work-Energy Theorem is correct?
The work done by conservative forces depends only on the initial and final positions of the object.
The work done by non-conservative forces depends only on the object's speed during motion.
Work can only be positive when the direction of force and displacement are the same.
The gravitational force always does positive work on an object moving upward.
Correct Answer
Detailed Explanation
The Work-Energy Theorem states that the work done by conservative forces, like gravity, depends solely on the initial and final positions, as noted in the NCERT context. Non-conservative forces and the direction of the gravitational force in relation to displacement lead to different scenarios.
