LAB 1: INTRODUCTION TO MOTION HOME WORK PART II VELOCITY-TIME GRAPHS After studying the velocity--time graphs you have made, answer the folowing questions 1. How do you move to create a horizontal line in the positive part of a velocity--time graph, as shown on the right? 2. How do you move to create a straight-line velocity-time graph that slopes up from zero, as shown on the right? e to the motions 3. How do you move to create a straight-line velocity time graph that slopes down, as shown on the right? is when you more o look at a dista tion of an objec 4. How do you move to make a horizontal line in the negative part of a velocity--time graph, as shown on the right? detector is the Ig them as 5. The velocity--time graph of an object is shown below. Figure out the total change in position (displacement) of the object. Show your work. Displacement =
