Energy Quiz

The Law of Conservation of Energy states:

• An object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by an outside force.

• Energy can neither be created or destroyed, but it can change form.

• For every action there is an equal and opposite reaction.

• The force acting upon an object is equal to its mass times its acceleration; the greater the mass of an object, the more force is required to move it.

How can the gravitational potential energy of an object be increased?

• By soaking it in water

• By throwing it upwards

• By weighing it on a spring scale

• By raising it higher above the ground
