Power and Energy

3. As a high-diver artist climbs to the top of the tower it’s --- increases.
4. Energy is changed by --- .
9. When work is done to a system to increase the energy of the system, the work is ---.
11. The work done by the high-diver to climb to the top of the tower is --- to the diver’s PEg at the top of the platform.
12. The --- the spring constant, the stiffer the spring and the more PEe that can be stored in the compressed spring.
14. The energy of a moving object.
15. Energy is the --- to do work.
16. Work is done when a force is the cause of the --- of an object
18. As a roller coaster speeds down the tallest hill it’s --- increases.
19. The stiffness of the spring is represented by the spring ---, k.
22. The PEg of a high diver on the platform is --- to KE as she dives and moves toward the water.
24. The sum of KE & PE of an object.
25. Work is not created or destroyed but can be --- from one object to another.

1. The “Law of --- of Energy” states that energy is neither created nor destroyed.
2. Jack lifts the 125-pound barbell over his head 10 times in 20 seconds and John lifts the 125-pound barbell over his head 10 times in 35 seconds. Who has more power?
5. Power is a --- meaning how fast work is done.
6. Mechanical energy due to an object’s position, we have studied two types in this unit.
7. The unit for measuring in work & energy.
8. When --- work is done on an a system, the energy of the system decreases.
10. The potential energy an object has due to its position above the surface of the Earth.
13. The unit for measuring power.
17. This type of potential energy is stored in an object that can deform and return to its original form, such as a spring or rubber band.
19. The --- of a spring is represented by the x in the equation for elastic PE.
20. The rate at which work is done.
21. Work is not created or destroyed but can be --- from one form to another.
23. A high-diver at the top of the platform has the --- PEg.
24. A roller coaster at the bottom of the highest hill has the --- PEg
