1. Section 1: Energy Changes Barr Batten

2. The ability to cause change Examples: Energy in a thunderstorm Pedaling a bike

3. Which has the ability to cause change? Bowling ball at rest or bowling ball moving

4. Energy due to motion Answer kinetic or not:

5. Mass mass = kinetic energy Speed speed = kinetic energy

6. Read p. 165 in groups Be prepared to answer these questions:

7. 1. What is the fastest a baseball has been thrown? What is its kinetic energy? 2. How can a tiny proton that bombards the earth have the same kinetic energy as the baseball? 3. Write your own question based on the reading.

8. Can be transferred when objects collide Ex: bowling pins Ex: dominoes

9. Kinetic Energy

10. Can you have energy if you’re not moving? Yes, stored energy is called potential energy

11. Which has more potential energy?

12. Height = potential energy Can you give me an example?

15. Law of Conservation of energy - energy cannot be created or destroyed (only changes form) Rub your hands together

16. Look at Figure 10 p. 169 How does energy get transformed when you kick a soccer ball?

17. Total amount of energy in the universe does not change
