| Light
Energy |
|
Anything that is luminous gives off light
energy. |
|
Things such as candles, bulbs and the sun give
off light energy. |

| Kinetic
Energy |
|
This is energy due to movement. |
|
Anything that moves possesses kinetic energy. |

|
| Gravitational
Potential Energy |
|
This is energy due to position above the
ground. |
|
When something is lifted up it gains energy. An
aeroplane and a snow boarder can fall and have potential energy. |

|
| Sound
Energy |
|
Sound energy is produced by a vibrating
object. |
|
Sound energy from a radio or a guitar travels in
waves to your eardrum. |

| Electrical
Energy |
|
When an electric current flows, there is
electrical energy. |
|
A current flowing in a circuit can provide
energy to power a computer. |

|
| Chemical
Energy |
|
Batteries, foods and fuels store energy which
can be produced in a chemical action. |
|
Our bodies are able to release energy from food
in a chemical process which involves oxygen. |

| Heat
Energy |
|
Above a temperature of absolute zero everything
has heat energy. |
|
A flask of hot water has more heat energy than a
flask of cold water because the molecules are moving more quickly. |
|

|
| Elastic
Energy |
|
When anything is stretched it has elastic
energy. |
|
Stretching the rubber of a slingshot allows
energy to be stored, which can be used to cast the shot. Energy
stored in the rubber band of a toy plane can make it move. |
