More Forms of Energy

1. More Forms of Energy

2. Forms of Potential Energy • Gravitational Potential Energy • Elastic Potential Energy • Chemical Energy • Nuclear Energy

3. Gravitational Potential Energy • The energy that results from its position above the ground • Any system of two or more objects separated by a distance contains gravitational potential energy • This results from the gravitational attraction between the objects

4. Elastic Potential Energy • The energy stored in any type of stretched or compressed elastic material • Examples include a clock spring, bungee cord, and rubber band • What would happen if I had a rubber band stretched out and then released it? • What happens when a compressed spring is released?

5. Chemical Energy • The energy stored within atoms and molecules that can be released when a substance reacts • Lets look at an example……

6. Nuclear Energy • Energy that comes from the splitting of an atom, or fusing two atoms together • This is an energy stored by the forces holding subatomic particles together in the nuclei of atoms • Lets imagine a water balloon……

7. Forms of Kinetic Energy • Radiant Energy • Thermal Energy • Sound • Electrical Energy

8. Radiant Energy • AKA light energy or electromagnetic energy • This is electromagnetic energy that travels in transverse waves • An example of this is solar power

9. Thermal Energy • This is energy that comes from heat and the vibration of atoms and molecules • Examples include geysers and coal burning • Another example is boiling water • As the water heats up the molecules began to vibrate and have an increase in velocity. In return this cause the water to heat up

10. Sound • Sound is the movement of energy through substances in longitudinal waves • Examples include echoes and music

11. Electrical Energy • This is another term for electricity • Our homes are powered by electricity • This results from the flow of charged particles through wires or other conducting materials
