| Question | Answer |
| What does Energy do? | Movement Sound Light Heat |
| What is work? | The effects of using energy |
| Name all forms of energy | Kinetic Heat Light Sound Electrical |
| Kinetic Energy | Anything that moves |
| Heat Energy | Heat energy can come from the Sun, flames, chemical reactions, electrical devices or even from a person or animal. Heat warms, burns, dries, melts, and makes hot-air balloons rise. |
| Light Energy | Light energy comes from the Sun, light globes, fires and animals such as glow-worms. |
| Sound Energy | Sound energy is the energy that air has when it is vibrating. Your ears and brain interpret the vibration of air as sounds. Sound comes from your voice, musical instruments, cars and power tools. |
| Electrical Energy | Electrical energy comes from power stations, solar cells, batteries, and sparks such as lightning. Electrical energy powers your TV, computer, microwave and toaster. |
| Stored Energy | Anything that is not in use has energy called - Potential energy |
| Types of potential energy | Gravitational potential energy Chemical energy Elastic potential energy Nuclear energy |
| Gravitational potential energy | Energy stored in an object when it is above the ground. The greater the height, the more gravitational potential energy an object has. |
| Chemical energy | Energy stored in an object when it is above the ground. The greater the height, the more gravitational potential energy an object has. |
| Elastic potential energy | Energy stored in a stretched or squashed spring. Stretched rubber bands also store elastic potential energy, which is released when they are let go. |
| Nuclear energy | Energy stored inside the small particles that make up all matter. Nuclear energy is released in a nuclear power plant, in a nuclear bomb explosion, and inside the Sun. Nuclear reactions produce heat and light. |
