| what does chemical energy do to your body | let ur heart beat, keep it moving and eat it up |
| what is photosynthesis | when plants make their food and eat |
| four different types of potential energy | gravitational elastic chemical nuclear |
| gravitational potential energy | energy stored in an object when it is above ground, the higher the object the more GPE |
| chemical | energy stored in substances, it is released by ur body when u digest food and by cars when fuels are burnt |
| elastic | energy stored in stretched or squashed objects and is released when let go |
| nuclear | energy stored in atoms that make up all matter. released in a nuclear power plant and when there is a nuclear explosion they produce light and heat |
