5. In order to determine speed, you must know a. time. b. distance. c. Both (a) and (b) d. None of the above Speed/Velocity/Acceleration 100

6. c. Both (a) and (b)

7. Speed/Velocity/Acceleration 200 What is the difference between speed and velocity?

8. velocity includes direction

9. Which of the following does not indicate velocity? a. 25 m/s SSE b. 55 km/h toward the town square along the main street c. 60 km/h going from Athens to Cleveland d. 42 km from Logan to Lancaster And WHY??? Speed/Velocity/Acceleration 300

10. d. 42 km from Logan to Lancaster km is just a distance, not a speed

11. Define acceleration. Include the units used to measure acceleration. Speed/Velocity/Acceleration 400

12. Acceleration is defined as the change in velocity divided by time. The unit used to measure acceleration is m/s2

13. Speed/Velocity/Acceleration 500 What are the 3 ways to accelerate (i.e change velocity) AND what must act upon an object in order to change velocity?

14. Speed up • Slow down • change direction/ • Velocity of an object changes when acted upon by (Unbalanced )FORCE

15. The combination of all of the forces acting on an object is called the a. total force. c. super force. b. union of forces. d. net force. Force 100

16. d. net force.

17. Which of the following best illustrates balanced forces (there may be more than one)? a. a rock falling to the ground b. a stretched rubber band being held between two hands c. a person lifting a heavy box off of the ground d. a crash between a large truck and a train e. a cyclist slowing down f. a leaf lying on the grass Force 200

18. b. a stretched rubber band being held between two hands f. a leaf lying on the grass

19. When the net force is zero… • Are forces balanced or unbalanced? • Does acceleration take place? • What will happen to a stationary object? Force 300

20. Balanced • No • It will remain at rest

21. A ball rolling across the floor starts to slow down… • Is the ball effected by a balanced or unbalanced force? • What is the force that is slowing down the ball? Force 400

22. Unbalanced Force • Some type of friction

23. Express the following as an equation: One newton is the force that can give an object with a mass of 1 kg an acceleration of 1 m/s2. (This answer must be written) Force 500

24. 1 N = 1 kg x 1 m/s2

25. Define Friction. Friction 100

26. force that opposes motion between two surfaces that are touching.

27. Which of the following statements is true? a. Frictional forces are greatest when both surfaces are rough. b. When a truck is parked on a hill, friction pulls the truck down the hill. c. Air resistance always opposes friction. d. Friction can exist between two objects even when they are not in contact. Friction 200

28. a. Frictional forces are greatest when both surfaces are rough.

29. What are the 2 main types of friction, define each? Friction 300

30. Static Friction (at rest) and Kinetic Friction (in motion)

31. What are the 3 types of kinetic friction? Give an example of each. Friction 400

32. Sliding- like a water slide/ rubbing your hands together • Rolling- like a bowling ball/ ball bearings • Fluid- drag/swimming

33. A car is parked on a hill. In order to keep the car from rolling downhill, how great must the static friction acting on the car be? Friction 500

34. equal to the force pulling the car downhill

35. Newton's Laws 100 Newton’s second law of motion states:

36. that the unbalanced force acting on an object equals the object’s mass times its acceleration (F=ma)

37. Which is the law that states that for every action force there is an equal and opposite reaction force? Newton's Laws 200

38. Newton’s 3rd Law

39. DAILY DOUBLE Newton's Laws 300

40. Newton’s 1st Law states that every object maintains constant velocity unless acted on by an unbalanced force. This law is also called the law of inertia. What is inertia and how does inertia increase? Newton's Laws 300

41. The tendency to resist change/ when an object has more mass.

42. What is the reaction force when you place a cup on a table? a. the force of the cup on the table b. the force of gravity on the table c. the force of gravity on the cup d. the force of the table on the cup Newton's Laws 400

43. d. the force of the table on the cup

44. List all three of Newton’s Laws and provide an example for each. Newton's Laws 500

45. Objects maintain a constant velocity unless acted on by an unbalanced force F=ma For every action there is an equal and opposite reaction force Examples will vary.

46. When is an object in motion? Miscellaneous 100

47. When it changes position relative to a stationary reference point

48. Give an example of displacement. Miscellaneous 200

49. 10 miles south 4 blocks left 2.7 kilometers toward the school Etc.

50. Miscellaneous 300 In the absence of air resistance, how would the acceleration of a 10 kg ball and a 1.0 kg ball differ if they were dropped from the same height? Why?
