1. To review for tomorrow’s quiz, play this review game. Use your checklist as you play! Ch.1-1 Motion

2. To play: • Read the question slide. • Wait until everyone in your group has an answer written down. • Click the powerpoint to the next slide and reveal the answer. • If you got the answer correct, great going! Check that off of your list. • If you got the answer incorrect, be sure to write the correct answer on your worksheet quickly! Instructions

3. Define velocity Question 1: Velocity

4. Velocity is the speed of an object in a particular direction. Answer 1: Velocity

5. Choose the reference point(s) in the following sentence. • First, you walk 2 meters and make a right at the McDonalds. Then you follow the arrows on the sidewalk to the yellow house on the left. Question 2: Reference Points

6. McDonalds • Arrows • Sidewalk • Yellow House Answer 2: Reference Points

7. Define Motion. Question 3: Motion

8. Motion is an objects change in position relative to a reference point. Answer 3: Motion

9. Explain how two racecars can be used as a reference point. Question 4: Motion

10. If two cars are racing each other, you can tell how fast each car is going relative to the other. • For example if there is a red car and a blue car in a race, I can tell that the blue car is winning because it is well in front of the red car (reference point). This tells me that the blue car is moving faster in reference to the red car. Star t Finish Answer 4: Motion

11. Define speed. Question 5: Speed

12. Speed is the distance traveled divided by the time interval during which the motion occurred. Answer 5: Speed

13. In the graph below, label the x and y axis if we were representing speed. Question 6: Speed

14. Distance (m) Time (s) Answer 6: Speed

15. Is the speed increasing or decreasing in the graph below? Question 7: Speed

16. Distance (m) Time (s) The speed is increasing in the graph because, as time goes by, the distance the car travels is increasing as well. Answer 7: Speed

17. Define acceleration. Question 8: Acceleration

18. Acceleration is the rate at which velocity changes over time. Answer 8: Acceleration

19. When does an object accelerate? Question 9: Acceleration

20. An object accelerates when it changes speed, direction, or both. Answer 9: Acceleration

21. Solve for the resultant velocity. • A dog is in a car traveling at a velocity of 87 m/s North. The dog runs to the front of the car with a velocity of 2 m/s. What is the dogs’ resultant velocity? Question 10: Resultant Velocity

22. 87m/s N + 2m/s N = 89 m/s North • You add the two velocities together because they are going in the same direction. • You know to add and not to use velocity=distance/time because we were not given data for distance or time.(be sure to read the word problems carefully to see what we are solving for) Answer 10: Resultant Velocity

23. A car is moving at a rate of 62 m/s south and accelerates at a rate of 6.0 m/s/s. What is its final velocity of the car after 4.0 seconds? Question 11: Acceleration

24. A car is moving at a rate of 62 m/s south and accelerates at a rate of 6.0 m/s/s. What is its final velocity of the car after 4.0 seconds? Answer 11: Acceleration

25. What are the two factors that determine acceleration? Question 12: Acceleration

26. Velocity and time (think about the formula) Answer 12: Acceleration

27. Is an object accelerating if it is slowing down? Question 13: Acceleration

28. Yes, an object is accelerating if it is slowing down because it is changing speed. It is negatively accelerating to be specific. Answer 13: Acceleration

29. If you travel 18 km and walk for 2.5 h, what is your average speed? Question 14: Speed

30. If you travel 18 km and walk for 2.5 h, what is your average speed? Answer 14: Speed

31. Write as many examples of reference directions as you can think of. Question 15: Reference Direction

32. North, South, East, West, Up, Down, Left, Right, Forward, Backward, just beyond, in front of, behind, etc. Answer 15: Reference Directions
