Question
1) How is a position vs. time graph for walking slowly away from the detector different from one for a person walking away more quickly? 2) How is a position vs. time graph different for a person walking toward the detector instead of walking away from the detector? 3) In general, how is motion that produces straight lines in position vs. time graphs different from that which produces curved lines? 4) How is a velocity vs. time graph for walking slowly away from the detector different from one for a person walking away more quickly? 5) How is a velocity vs. time graph different for a person walking toward the detector instead of walking away from the detector? 6) Do you think is it possible to move in a way that produces a vertical line on a velocity vs. time graph? Why or why not? 7) In part VI, did you run into the motion detector? If so, how did you fix this problem? Does the velocity vs. time graph give information about the initial position? 8) You are walking down the sidewalk, and another student catches up and then passes you. At that moment, which quantity is the same for both of you: position, velocity, or both? Explain. 9) How can you tell from a velocity vs. time graph that a moving object has changed direction? What is the velocity at this point? 10) How can you tell from a position vs. time graph that the velocity is constant? 11) How can you tell from a velocity vs. time graph that the velocity is constant?Explanation / Answer
1. The slope of the line. The more the slope, more is the speed
2. slope of line will be positive for person moving towards, and negative for the person moving away from the detector
3. Straight line indicates uniform speed (or rest), while curve indicates non uniform speed
4. the Line for higher velocity will be up as compared to line with less velocity
5. Graph will be plotted with positive velocity for person moving towards, while it is plotted negative for person moving away from the detector.
6. Not possible, since vertical line indicates same time, no change in time, therefore velocity cann't change
