Law of conservation of energy states that total energy of an isolated system__________

Law of conservation of energy states that total energy of an isolated system__________

a. Increases
b. Decreases
c. Remains constant
d. Increases and decreases over the period of time

Correct Answer: c. Remains constant

Explanation

If a particle or a body is acted upon by a conservative force system, the sum of the kinetic energy and the potential energy of the system remains constant. And the total energy is the sum of kinetic energy and potential energy. Thus the total energy of an isolated system remains constant.
