Question

If the velocity of a body is halved what will be the change in kinetic enegy?

Answer 1

Answer:

If the velocity of a body is halved, its kinetic energy becomes one fourth as kinetic energy is directly proportional to velocity squared.

Answer 2

Answer:

Kinetic energy of a body is directly proportional to the square of velocity. So, the kinetic energy will become the initial kinetic energy when velocity is halved
