Question

Suppose a moving object has kinetic energy and then comes to rest. What describes the change in its kinetic energy?

A. It would remain constant.
B. It would double.
C. It would decrease by half.
D. It would become zero.

Answer 1

Answer: D

Explanation: The kinetic energy would become Zero.

According to conservative of energy, the total energy is equal to maximum K.E plus maximum P.E.

As the object comes to rest the potential energy will be maximum, and Kinetic energy becomes zero.
