Physics 112 Written Assignment #2 Chapter 2: One-Dimensional Kinematics 1. Displacement and position are related, but are not the same thing. a) Write a sentence or two describing the difference between position and displacement, and give one example of each. b)Under what circumstances does distance travelled equal the magnitude of displacement? 2. A skateboarder moves in a straight line for 12 s. The skateboarder has an initial position which is negative with respect to a chosen origin, and her velocity is also negative during the entire 12 s. At the end of 12 s, is the skateboarder closer to or further from the origin than she was originally? Explain. 3. A puppy runs along a straight line. The puppy’s velocity, v , as a function of time is shown in the graph below: a) Describe the puppy’s motion between 0 to 14.0 s. b) Calculate the puppy’s average acceleration between 0.0 seconds and 12.0 seconds.
