Motion Test 1. Which pendulum to the right has the longest period? Name _____________________ A B C a) A b) B c) C 2. Which of the following has a significant influence on the period of a simple pendulum? a) b) c) d) mass amplitude length Misleading – all three have a significant impact on the period of a simple pendulum. Complete each row providing the two missing components; use pencil to make graph drawings. Distance-time graph Velocity-time graph 3. Written Description 4. (Note 3 horizontal graph segments.) 5. 7. 6. 8. An object moves with constant positive velocity for 4 seconds. Then, it stops for 2 seconds and returns to the original position in 2 seconds. Questions 9, 10, and 11 relate to the following graph showing uniformly accelerated motion. 9. Give a written description of the motion of this object. 10. Explain how you could determine the instantaneous velocity of the object at t = 2 s. 11. Assume the initial velocity was 50 m/s, determine the acceleration of the object. 12. A car, initially at rest, accelerates at a constant rate of 4.0 m/s2 for 6 s. How fast will the car be traveling at t = 6 s? 13. A tailback initially running at a velocity of 5.0 m/s becomes very tired and slows down at a uniform rate of 0.25 m/s2. How fast will he be running after slowing down for 4 seconds? 14. Which of the following is NOT accelerating? a) b) c) d) a car moving at constant velocity a car moving around in a circle at constant speed both responses a and b Misleading – both a and b are accelerating Part 3 – Reflection Multiple Choice; Reflection I missed question # ________ because I answered letter ______.
