1. PENDULUM WORKSHEET 1 is where PE is the greatest
3 is where PE is the least
3 is where the KE is the greatest
1,5 is where KE is the least
2,4 is where KE = PE
0 is how many Joules of KE the pendulum has at point 1

2. PENDULUM WORKSHEET
7. Explain why the pendulum has the most KE at point 3 8. Why is point 5 a little lower than point 1? Where and how is that small amount of PE lost?

3. PENDULUM WORKSHEET
9. Explain why the pendulum has the most PE at point 1? 10. Show the steps that the energy goes through from the sun to the pendulum.

4. PENDULUM WORKSHEET
11. How could you have a pendulum have more KE when it gets to point 3?

5. PENDULUM WORKSHEET
12. If the pendulum was lifted 0.5 m higher at point 1 than at point 3, and the mass of the bob (the weight on the end of the pendulum) was 0.25 kg, how much GPE does the bob have? Show your work with units!

6. PENDULUM WORKSHEET
13. How much KE does the pendulum have if its velocity is 1.2 m/s? Remember, the mass of the bob is still 0.25 kg. Show your work with units!

7. PENDULUM WORKSHEET
14. Find the height of a pendulum with a mass of 0.15 kg that has a GPE of 73.5 J. Show your work with units!

8. PENDULUM WORKSHEET
15. A pendulum moving at a speed of 20 m/s has a kinetic energy of 300,000 J. What is the pendulum’s mass? Show your work with units!

9. PENDULUM WORKSHEET
16. What is the kinetic energy of a pendulum moving at a speed of 40 m/s if the pendulum has a mass of 0.15 kg? Show your work with units!

10. PENDULUM WORKSHEET
17. Find the GPE of a pendulum with a mass of 0.3 kg on a 2.6 m countertop. Show your work with units!

11. PENDULUM WORKSHEET
18. What is the mass of a pendulum 200 m above the ground if its GPE is 117,600 J? Show your work with units!

12. PENDULUM WORKSHEET
19. A pendulum has a mass of 80 kg and a kinetic energy of 4,000 J. What is the pendulum’s speed? Show your work with units!
