4.3. It can be measured in joules.
4.3.1. K.E. = 1/2 m v2
4.4. Factors that it depends on are the mass of an object, and speed of an object.
4.5. It is related to mass because it depends on how much mass it is exerting force on to figure out how strong the force will be.
4.6. It is related to speed because the velocity that it is going at depends on how much mass it is pushing, and how much energy is exerted.

5. What is energy?
5.1. The strength needed to perform a physical or mental activity.
5.2. Must be transferred to an object in order to perform work on, or heat an object.
5.3. Energy changes forms.
5.3.1. A toaster changes electrical energy into thermal energy.
5.3.2. A blender changes electric energy into mechanical energy.
5.3.3. Our bodies change chemical energy in our food into mechanical and electrical energy, so we can move.
5.4. Measured in joules
6. Where does energy come from?
6.1. Most energy comes from the sun
6.2. Plants absorb sunlight, and when we eat them, they give us 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.
