2. Accelerated motion is represented by this type of line on a distance-time graph.

3. What is curved?

4. Objects in free fall near the surface of the Earth experience this

5. Constant acceleration?

6. An object moving at 60 m/s takes 10 s to come to a stop. What is the objects acceleration?

7. 0m/s – 60 m/s = 10 s -6 m/s 2

8. A push or a pull is an example of this.

9. What is a force?

10. A car traveled 90km in 1 hour, 100km in the next 2 hours, and 80 km in 1 hour. The car’s average speed is this.

11. Total distance/total time (90km + 100km + 80km) (1hr + 2hr + 1hr) = 67.5 km/hr

12. The property of matter that resists changes in motion is called this.

13. What is inertia?

14. These changes occur in motion to cause acceleration

15. What are speed up, slow down, and change direction?

16. You walk to class at 2 m/s and need to get to Science class 250m away. How long does it take to make it there?

17. 250 m x 1s = 125s 2m

18. As you get further from the Earth this happens to your weight.

19. What is decreases?

20. The Muskegon river has a current of 10km/hr relative to the shore. How fast does a boat traveling at 5km/hr move with the rivers current?

21. 10 km/hr + 5 km/hr = 15km/hr

22. The type of friction when riding a skateboard.

23. What is rolling friction?

24. The curved motion of a thrown object.

25. What is projectile motion?

26. The universal force that is affective over long distances.

27. What is gravity?

28. Needed to determine motion.

29. What is a frame of reference?

30. This is the primary cause of the Earth’s tides.

31. What is the moon’s gravity?

32. A force is applied and motion occurs in the same direction as the force.

33. What is work?

34. Formula and units for work.

35. Work = Force x Distance (Nm = Newton's x Meters) AND 1 Joule = 1 Nm

36. You do 50 joules of work lifting a 100 N box, this is how high you lift the box.

37. W = F x d d = W/F 50 Nm/100N =.5m

38. The mass of a toy truck is 5kg. Convert this to weight.

39. W = m x g W = 5kg x 9.8m/s 2 = 49 N (remember kgm/s 2 = N)

40. A crane lifts a 1,000 kg steel beam with a force of 500 N. What is the acceleration of the beam?

41. Force = Mass x Acceleration F=MA A= F/M 500N/1,000kg = 0.5 m/s 2 Reminder N = kgm/s 2

42. Mechanical Energy can be broken into these categories.

43. What are Kinetic and Potential reminder KE = ½ mv 2 PE = mgh

44. Unit for Energy

45. Joules

46. A 6 kg bowling ball is on a shelf 2 meters high. Find the amount of GPE.

47. GPE = mgh 6kg x 2m x 9.8m/s 2 = 118 J

48. The energy stored in propane gas.

49. What is chemical

50. Solar calculators covert this energy into electrical energy.

51. What is electromagnetic
