Question

when a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?
o work
o power
o gravitational energy
o chemical energy

Explanation:

Work is the transfer of energy. When a spring is compressed, work is done on the spring. This work causes the energy to change from kinetic (if there was motion initially) to potential (elastic potential energy in the spring). Power is the rate of doing work. Gravitational energy is related to height in a gravitational field. Chemical energy is stored in chemical bonds. So, the cause of the energy change (kinetic to potential in the spring) is work.

Answer:

A. work
