Calculate the total distance traveled by the object during the first 3.0 seconds. Identify the interval during which the object’s magnitude of the acceleration is greatest. During the interval t=8.0 seconds to t=10.0 seconds, the speed of the object is Zero c) increasing Decreasing d) constant but not zero Which pair of graphs represents the same motion? A displacement-time graph has a constant slope. What quantity must have a constant slope? Speed c) velocity Acceleration d) displacement Base your answers to questions 14-17 on the following four graphs which represent the relationship between speed and time for four different objects, A, B, C, and D moving, in a straight line. Which object was not accelerating? object traveled the greatest distance in the 3.0 second time interval? Which object had the greatest acceleration? Compared to the average speed of object A, the average speed of object D is 1) less 2) greater 3) the same The time rate of change of displacement is Acceleration c) distance Speed d) velocity Base your answers to questions 19-22 on the following graph, which represents the relationship between the displacement of an object and time. How far is the object from the starting point at the end of 3 seconds? During which time interval is the object at rest? What is the average velocity of the object from t=0 to t=3 seconds? 1 m/s c) 2 m/s 3 m/s d) 0 m/s During which time interval is the object accelerating?
