NEET Physics Kinetic Energy MCQ Question
Which of the following statements about kinetic energy is correct?
Kinetic energy is conserved in elastic collisions if no external forces act on the system.
Kinetic energy can be negative if the object is moving in the opposite direction.
Kinetic energy is always equal to the potential energy of a spring at maximum compression.
Kinetic energy increases as an object's mass decreases, provided its velocity remains constant.
Correct Answer
Detailed Explanation
In elastic collisions, the total kinetic energy before and after the collision remains constant, which aligns with the principle of conservation of kinetic energy discussed in the context of collisions. Other options misinterpret kinetic energy or its relationship with mass and potential energy.
