| A | B |
| Heat | Thermal energy. The total energy of molecules in a substance. |
| Temperature | A measure of the kinetic energy of substance |
| Kinetic energy | Energy of movement |
| Kelvin | This scales uses an absolute zero |
| -273 | Absolute zero in degrees celsius |
| Thermometer | Used to measure temperature |
| Kinetic theory of matter | Theory that explains how the particles are arranged in different states of matter and what happens when they are heated or cooled |
| Solar | The sun produces this sort of energy |
| Potential Energy | Stored energy |
| Chemical Potential Energy | Energy stored in food or in batteries. |
| Elastic Potential Energy | Energy stored when things are stretched or compressed. |
| Nuclear Energy | Energy released when chemical bonds within particles in a nucleus are broken. |
| Sound | Form of energy which we can 'hear' |
| Electrical Energy | Energy which is carried by moving charges such as electrons. |
| Light | Energy we can 'see' |
| Electromagnetic | Describes waves that do not need a physical medium in order to travel. |
| Mechanical Energy | Both potential & kinetic energy. |
| Radiant | This can be used to describe light or heat. |
| Absolute Zero | The lowest temperature approachable |
| Energy | all particles above Absolute Zero have this |
