2. Energy is defined as …

3. the ability to do work.

4. Energy of motion is…

5. kinetic energy.

6. Potential energy is defined as…

7. stored energy.

8. Explain the difference between kinetic and potential energy.

9. Kinetic energy is energy when something is moving. Potential energy is energy that is stored up waiting to be released.

10. The math formula to calculate potential energy is: of an object about to fall is (PE=

11. PE = weight (of the object) x height (where the object is above the ground)

12. Energy stored in the nucleus is…

13. nuclear energy.

14. Energy of moving things like bicycles is…

15. mechanical energy.

16. Energy in moving electrons is…

17. electromagnetic energy. (electricity)

18. Energy of moving microscopic particles of matter is… [Friction creates this.]

19. heat energy. [The faster the particles of a substance are moving, the warmer the substance is.]

20. Energy that holds particles of matter together is …

21. chemical energy.

22. Ryan Miller saves an attempt on goal hit by Crosby with 20N of force. The ice exerts 2 N of friction on the puck. What is the net force? (What force is left over after the friction is taken away?)

23. Net force = force exerted - friction. 20N - 2N = 18N

24. What is the formula to calculate speed?

25. Speed = distance divided by time. Ex. =>miles per hour =>meters per second

26. Ryan Miller kneels in front of the net. His pads put 30N of force on 6 square feet of area. How much pressure is exerted on the ice? Pressure = force divided by area

27. Pressure = force / area P = 30N / 6 sq. ft. P = 5N per sq. ft

28. Ryan Miller saves a shot from Crosby hit with 10N of force from a distance of 30 m. How much work did Crosby do in that shot? Work = force x distance

29. Work = force x distance w = 10N x 30m w = 300N-m

30. What is the formula for acceleration?

31. Acceleration = (final speed - initial speed) divided by time Ex. (60 mph - 10mph) / 10 sec acceleration = 50mph / 10 sec acceleration = 5mph/sec

32. The ability to do work is defined as…

33. energy.

34. Speed is defined as …

35. distance traveled in a certain amount of time.

36. Velocity is defined as…

37. speed traveled in a certain direction.

38. Friction is defined as…

39. force that opposes the motion of an object.

40. Motion is defined as …

41. a change in position.

42. How many laws of physics did Newton describe?

43. There are 3 Newton’s Laws.

44. An object at rest tends to …

45. stay at rest [unless acted on by an unbalanced force].

46. What word is used instead of saying “Newton’s First Law of Motion?”

47. inertia

48. Newton’s Second Law says force is equal to mass times … f = m x ?

49. acceleration.

50. Complete Newton’s Third Law: For every action there is …

51. an equal and opposite reaction.
