The principle of conservation of mechanical energy states that:

The total mechanical energy (kinetic + potential) in a closed system remains constant, assuming no non-conservative forces are acting.

The total energy in a closed system decreases over time.

Kinetic energy is always larger than potential energy.

Potential energy can be converted into kinetic energy but not vice versa.

If the velocity of an object doubles, by what factor does its kinetic energy change?

Increases by a factor of $$\sqrt{2}$$

What is the Law that State energy can neither be created nor destroyed, just converted from one form to another?

The Law of Conservation of Energy

The Constitution of the United State of America

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy?

The PE decreases while the KE increases

The PE and KE increase and decrease together

Impossible to know without knowing the mass
