1. EnergyEnergy Energy Conversions

2. Energy Conversion A change from one form of energy to another.

3. Example Pendulum - Starts as potential energy, as it swings downwards it changes to kinetic energy, when it hits its lowest point it goes back to potential energy, as it swings upwards it is kinetic energy and when it hits its highest point again it turns into potential energy.

4. Example #2 Rubber band - Starts as potential energy until you stretch it, it turns into kinetic energy. When you have stretched to its maximum elasticity it turns back into potential energy and when you let go it turns back into kinetic energy.

5. Example #3 Soccer ball - When the ball is resting on the ground it has potential energy. When a player kicks the ball the potential energy is turned into kinetic energy. As the ball rolls it slows down and eventually stops returning to a state of potential energy.

6. Example #4 Running: Sun (light) --- tree (chemical) --- fruit (chemical) --- person eating fruit (chemical) - -- person running (mechanical)

7. Example #5 Hair dryer: Electrical outlet (electromagnetic) - -- hair dryer (sound, thermal, light)

8. Example #6 Light Bulb: Electrical wiring (electromagnetic) - -- light bulb (light, thermal)

9. Example #7 Golf Player: Stored lunch (mechanical: potential) --- swinging the club (mechanical: kinetic) --- ball flying (mechanical: kinetic, sound)

10. Law of Conservation of Energy Energy cannot be created nor destroyed. It can be transferred from one object to another.
