What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has potential energy.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.
