Get Started. It's Free Energy 1. What is energy?

1.3. Energy changes forms.

1.3.1. A toaster changes electrical energy into thermal energy.

1.3.2. A blender changes electric energy into mechanical energy.

1.3.3. 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.

8.2. Types

8.2.1. Gravitational

8.2.2. Chemical

8.2.3. Nuclear

8.2.4. Elastic

8.3. It can be measured in joules.

8.3.1. P.E. = mgh

8.3.1.1. mgh= mass, gravity, height

8.4. Factors that affect potential energy.

8.4.1. Mass

8.4.2. Height

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.
