5.3.3. Our bodies change chemical energy in our food into mechanical and electrical energy, so we can move.

## 8. Potential Energy

### 8.1. What is it?

8.1.1. Energy that is possessed by an object based on the position relative to other objects.

### 8.6. Types of Forces that possibly exist between two objects which will be overcome by using energy.

8.6.1. All conservative forces, like gravity, elastic collisions and spring forces.

8.6.1.1. A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the taken path.
