Question

If the kinetic and potential energy in a system are equal, then the potential energy increases. What happens as a result?

Total energy increases.
Stored energy decreases.
Energy of motion decreases.
Total energy decreases.

Answer 1

energy of motion decreases is the answer. coz total energy in a system remains constant if not interfered external agency. therefore if PE increases KE should decrease

Answer 2

If the kinetic energy and potential energy in a system are equal and potential energy is increased then the "energy of motion decreases".

EXPLANATION:

This happens because when potential energy increased, kinetic energy which is energy of motion decreases. This decrease in energy is essential so that the body can stay in a balance. To make sure that balanced forces act on the body, the kinetic energy decreases with the increase in potential energy.
