when a spring is compressed, the energy changes from kinetic to potential. which best describes what is…

Brief Explanations:

Work is done on the spring when it is compressed. This work causes the kinetic energy of the object compressing the spring to be converted into elastic - potential energy stored in the spring. Power is the rate of doing work and not the cause of the energy change. Gravitational energy is related to an object's height in a gravitational field and is not relevant here. Chemical energy is stored in chemical bonds and not involved in this spring - compression scenario.

Answer:

A. work
