NEET Physics Kinetic Energy MCQ Question
Which combination of statements about kinetic energy is correct?
Kinetic energy is conserved in elastic collisions, and it can be transformed into potential energy.
Kinetic energy depends only on the mass of an object and not on its velocity.
In elastic collisions between two objects of equal mass, the total kinetic energy before and after the collision remains the same.
Kinetic energy can be calculated using the formula K = 1/2 mv^2, but is not relevant in nuclear reactions.
Correct Answer
Detailed Explanation
Kinetic energy is conserved during elastic collisions and can indeed be transformed into potential energy, as noted in the context regarding conservation of mechanical energy. Options B, C, and D contain misconceptions about kinetic energy.
