NEET Physics Kinetic Energy MCQ Question
Which of the following statements about kinetic energy in elastic collisions is correct?
In elastic collisions, total kinetic energy is conserved regardless of mass.
Kinetic energy can be lost in elastic collisions if the masses are unequal.
The kinetic energy after an elastic collision is always less than before.
Elastic collisions can occur only between objects of equal mass.
Correct Answer
Detailed Explanation
In elastic collisions, the total kinetic energy is conserved, even when the masses are different, as demonstrated by the equations provided in the context. This means that the initial kinetic energy is equal to the final kinetic energy of the system after the collision.
