potential energy | stored energy |
kinetic energy | energy of motion |
energy | The ability to do work or to create change. |
electrical energy | The movement of electrical charges called electrons. |
mechanical energy | A form of energy calculated by adding the potential and kinetic energy of a system. |
chemical energy | the energy released when chemical bonds are broken. |
thermal energy | The vibration and movement of atoms and molecules within substances. The higher the temperature the faster the movement. |
nuclear energy | The energy that holds the nucleus of an atom together. It is released when the nucleus of an atom is broken apart or joined together with another atom's nucleus. |
radiant energy | Electromagnetic energy that travels in waves. Examples include: visible light, x-rays, gamma rays, microwaves and radio waves. |

Law of Conservation of Energy | Energy is neither created nor destroyed, it just changes forms. |
A person about to jump from the high dive has: | gravitational potential |
Sunlight is an example of | Radiant energy |
Food is an example of | chemical energy |
A stretched rubber band is an example of | Elastic potential |
Motion energy | Energy stored in the movement of objects. The faster they move, the more energy is stored. |
Gravitational | Potential energy that increases the higher an object is above the surface of the Earth. |
