1. Energy
A measure of the ability of an object to produce a change in itself or its environment

2. Types of Energy
Potential: stored
Kinetic: motion

3. Potential Energy Gravitational
Each diver has an amount of stored energy based on mass and height

4. Potential Energy Gravitational
The climber acquired a large amount of potential energy in the climb up from the water

5. Potential Energy: Gravitational

6. Potential Energy Elastic
Energy has been stored in the pole by bending it

7. Potential Energy

11. Potential Energy: Elastic

12. Kinetic Energy
The diver is moving at a high rate of speed when he enters the water

13. Kinetic Energy
47,000 runners
have a large amount of motion energy

14. Kinetic Energy

15. Forms of Energy Mechanical Thermal Chemical Electrical Electromagnetic
Nuclear

16. Energy is Energy. Forms of Energy
We group energy into different forms to help us understand different physical situations. Nature does not make these distinctions.
Energy is Energy.

17. Energy Conversion
Energy can change type
KE → PE

18. Energy Conversion Electrical → Thermal → Electromagnetic
Energy can change form
Electrical → Thermal → Electromagnetic

19. Energy is Energy! Energy Conversion
All these changes can occur because
Energy is Energy!

20. Energy Transfer
Energy can move from object to object

21. Energy Conservation The total amount of energy is always constant
Energy is neither created nor destroyed

22. Energy Conservation
ΣW = ΔKE + ΔPE + ΔQ

23. Matter and Energy can each be transformed to the other
Matter – Energy
Matter and Energy can each be transformed to the other
Nuclear Reactions
