Answer: The statement when the motion energy of an object changes, energy is being transferred is true.
Step-by-step explanation:
Motion energy is also called mechanical energy and it is the summation of kinetic energy and potential energy stored in an object required for work.
As kinetic energy is the energy acquired due to motion of an object and potential energy is the energy acquired by an object due to its position.
For example, when a moving ball strikes another ball causing it to move then energy is being transferred from one ball to another.
Therefore, the statement when the motion energy of an object changes, energy is being transferred is true.
