21. What is potential energy to kinetic energy? B 300

22. B 400 This is the law that states that energy can neither be gained or lost, only change form.

23. B 400 What is the Law of Conservation of Energy?

24. B 500 Both of these diagrams show this type of energy transformation.

28. C 200 This piece of science equipment is used to find the weight or force of an object.

29. What is a spring scale? C 200

30. C 300 This is the acceleration due to gravity in Earth

31. C 300 What is 9.8 m/s 2

32. DAILY DOUBLE C 400 DAILY DOUBLE Place A Wager

41. D 300 This Law of Motion shows the relationship between mass and force.

42. D 300 What is the Law of Force and Acceleration?

43. D 400 A person in a head-on car collision who is not wearing a seat belt continues to move forward at the original speed of the car because of ______________

44. What is inertia? D 400

45. D 500 Newton’s Law of Inertia says “objects in motion stay in motion unless acted on by an outside force.” Objects in the back seat of a car would move this direction if the car suddenly stopped.

46. What is forward? D 500

47. E 100. This Law of Motion best explains why you may lean sideways in a car if the driver turns a corner too quickly.

48. What is the Law of Interia? [Newton’s 1 st Law] E 100

49. E 200 A rocket is traveling in space at 10,000 m/s. If no outside force is applied to it, this will happen to its speed over the course of the trip.

50. What is stay the same? [or stay constant] E 200

51. E 300 The air friction acting on a baseball causes it to curve as it is pitched to the catcher. This is an example of Newton’s Law of ________________

52. What is inertia? E 300 [Objects in motion remain in motion unless acted on by an outside force. Here, the outside force is gravity causing the ball to curve down.]

53. E 400 You are riding in a car that has a coffee cup sitting on the dashboard. The vehicle makes a sudden stop to avoid hitting the car that has stopped in front of it. This would happen to the coffee cup.

54. E 400 What is move forward [until it hit the windshield]

55. E 500 Jumping on a skateboard and watching the skateboard move away from you is an example of this Law of Motion

56. What is Action-Reaction? E 500

57. F 100 The two forces in a force pair are the ____________ force and the _____________ force.

58. F 100 What are action and reaction?

59. F 200 This is the point on the roller coaster above with the greatest gravitational potential energy.
