NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about the relationship between work done and kinetic energy is correct?
A
The work-energy theorem states that the work done by a variable force equals the change in kinetic energy.
B
The work done by any force always results in an increase in kinetic energy.
C
The work-energy theorem applies only when the force is constant throughout the motion.
D
Kinetic energy can be negative if the work done is negative.
Correct Answer
Option A
Detailed Explanation
The work-energy theorem asserts that the work done is equal to the change in kinetic energy, which is specifically highlighted in the context of variable forces and integration from initial to final positions.
