1. Kinetic and Potential Energy have many forms

2. 1. Mechanical Energy - Energy associated with motion or position

3. Examples: most moving objects have mechanical energy

4. 2. Thermal Energy (Heat) - Total energy of the particles in an object

5. Example: Heating causes the particles to move faster = more thermal energy

6. 3. Chemical energy - Energy stored in chemical bonds

7. Examples: wood, food, gasoline, batteries

8. 4. Electrical energy - Energy of moving electrons

9. Example : electric outlet

10. 5. Radiant or Electromagnetic (Light) energy Travels in waves

11. Examples: lightbulb, microwave

12. 6. Sound energy- Caused by an object’s vibrations

13. Example : guitar, boombox

14. 7. Nuclear energy - Potential energy stored in the nucleus of an atom

15. Example : nuclear power plants, sun

16. Energy Conversions - A change from one form of energy to another

18. Conversion example 1 Lamp : electrical energy converts to light energy

19. Conversion example 2: Water heater : Chemical energy of gas to thermal (heat ) energy

20. Conversion example 3: Human body : converts chemical energy in food to mechanical energy

21. Energy is Conserved

22. Energy is conserved

23. Energy is Conserved

25. Pendulum
