3. Luis wants to make a graph of his physics grade over the course of first semester. Which type of graph should he choose to make?

4. Line Graph Change over time

5. Convert 80800000 into scientific notation.

6. 80800000 = 8.08 x 10 7

7. DOUBLE JEOPARDY Which of the following measurements is the smallest? a.5.4 Km b.54000 cm c.54 Hm d.5400 m

8. b. 54000 cm a.5.4 Km b.54000 cm = 0.54 Km c.54 Hm = 5.4 Km d.5400 m = 5.4 Km

9. Draw a picture that shows precision, but NOT accuracy.

11. Convert 3.0222 x 10 -2 into regular notation.

12. 3.0222 x 10 -2 = 0.030222

13. Choose the correct word to finish the sentence: When the forces on an object are balanced, the object is (moving/stationary).

14. Stationary = not moving

15. What is the net force of the car below??

16. 10 – 7 = 3 N to the RIGHT

17. What is the force that is the opposite of gravity??

18. Normal Force – goes up Gravity – goes down

19. Draw a force diagram of a car driving east.

21. True or False: Friction is necessary in order to walk.

22. True or False: Friction is necessary in order to walk. Without friction, you would just slide around.

23. Fill in the blank with the correct words: According to Newton’s Third Law, every action has an _________ and ___________ reaction.

24. According to Newton’s Third Law, every action has an equal and opposite reaction.

25. What is the formula the describes Newton’s second law?

26. F = m a Force = mass x acceleration

27. Calculate the force of a car that has a mass of 1200 kg and is accelerating at 2 m/s.

28. F = m a F = (1200 kg) (2 m/s) F = 2400 N

29. What is Newton’s first law of motion?

30. An object at rest remains at rest unless acted on by an outside force. An object in motion remains in motion unless acted on by an outside force.

31. DOUBLE JEOPARDY!! Below is a picture of a toy called “Newton’s cradle.” Which of Newton’s 3 laws does this toy help to demonstrate??

32. This toy is used to help demonstrate Newton’s 3 rd law: each action has an equal and opposite reaction.

33. What is the equation for calculating speed??

34. S = d/t Speed = distance/time

35. Calculate the speed of a car that drives 15.4 km in 23 mins.

36. S = d/t S = 15.4 km/23 mins S = 0.67 km/min

37. A car is moving at a constant velocity of 20 km/h west for 2 hours. Is the car accelerating? Why or why not?

38. The car is NOT accelerating because it is at a constant velocity. Acceleration is a change in velocity. If the velocity doesn’t change, then it is not accelerating.

39. What is the difference between speed and velocity?

40. Speed doesn’t have a direction and velocity does.

41. DOUBLE JEOPARDY!! The person walks from A  B  C  D. What is the distance? What is the displacement?

42. The person walks from A  B  C  D. What is the distance? 4+8+4 = 16m What is the displacement? 8m

43. Which of the following is metric unit of measurement for volume? a.Gram b.Liter c.Meter

44. b. Liter

45. Fill in the blank with the correct word: _________ causes objects to accelerate towards the Earth.

46. Gravity causes objects to accelerate towards the Earth.

47. Which of the following words means the same thing as Dependent Variable? a.Manipulated b.Measured c.Controlled d.Varied

48. b. Measured

49. What is the difference between mass and weight?

50. Mass is how much space an object occupies. Weight is how much force gravity has upon an object.

51. List all of the words that are synonyms of Independent Variable.

52. Independent Variable, what the scientist: Manipulated Varied Changed Altered
