1. Energy Transformations PS9.15

2. Energy is found in different forms
Kinetic energy types
Electrical – the movement of electrons(electricity)
Light energy – electromagnetic energy that travels in transverse waves.
Heat energy – the vibration and movement of the atoms and molecules in a substance

3. More kinetic energy types
Mechanical energy – the movement of objects from one place to another.
Sound – the movement in longitudinal waves. Caused by vibrations.

4. Potential energy types
Chemical energy – energy stored in bonds of atoms and molecules. Propane, natural gas, and petroleum are examples.
Elastic energy – energy stored in objects. A compressed spring or a stretched rubber band are examples.

5. More potential energy types
Nuclear energy – energy stored in the nucleus of an atom. Energy is given off by either nuclear fusion or nuclear fission.
Gravitational energy – energy of position. Hydropower is an example.
