AP Physics Chapter 2 Test Review Use the GUESSS method for problems that need working out! 1. Describe the motion of an object moving in a straight line at constant velocity of 2m/s 2. Sketch and explain the position vs. time graph of the object in question 1 above 3. Describe the motion of an object moving in a straight t line at constant acceleration of 2m/s2 4. Sketch and explain the position vs. time graph of the object in question 2 above 5. Is an object undergoing negative acceleration necessarily slowing down? Can it be speeding up? Explain giving examples. 6. Compare the final velocity (just before hitting the ground) of two marbles falling from the same height, one thrown downward and the other falling from rest. 7. Considering the cliffs are of the same height in the diagram below, does object ‘b’ hit the ground with a greater velocity than object ‘a’. Explain 8. Explain the motion of a coin as it is tossed up in the air and falls back into your hand as you hold it at the same position. 9. A tennis ball is dropped from a height if 10m, how long does it take for the ball to reach the ground? Use the graph to your right to answer the following questions: 10 – 13 10. During which segment is the object travelling equal distances in equal times? 11. How far does the object move in each segment? A, B and C 12. During which segment does the speed of the object increase by equal amounts in equal times? 13. What is the acceleration of the object at each segment? Use the graph to your right to answer the following questions: 14 – 17 14. In which section of the graph, is the object moving at its highest speed? 15. In which section of the graph, is the object moving at its lowest speed? 16. In which section of the graph, is the object moving in a positive direction 17. In which section of the graph, is the object moving in a negative (reverse) direction Akibola – not for a grade (use your notes – there is no key) Page 1 AP Physics Chapter 2 Test Review Use the GUESSS method for problems that need working out! 18. A rock is dropped on planet ‘Alpha Centauri Bb’, and attains a speed of 35m/s after falling for 5.0m a. How long did it take for the rock to fall the 5.0 m? b. What is the magnitude of the acceleration due to gravity on planet ‘Alpha Centauri Bb’? c. What is the speed of the rock after falling for 10.0m on planet ‘Alpha Centauri Bb’? d. How long would it take for the rock to fall the 10.0m? Use the graph to your right to answer the following questions: 19. What can you say about the acceleration of the object whose motion is shown in the graph to your right? 20. If the graph shown above represents the motion of an object in free fall with no air resistance. Sketch on a graph on an object in free fall under the influence of significant air resistance. 21.
