5. Compare the distance versus time graph with the bar graph of speed versus distance. a) When the distance versus time graph is curving early in the run, do the bars on the bar graph change in height or are they fairly steady in height? What does this comparison mean? When the graph is climbing in a straight line, what is happening to the heights of the bars on the bar graph? What does this comparison mean? b) Someone said, “The slope, or steepness, of a distance versus time graph at any instant is the speed at that instant.” Do you believe this statement? Why or why not? c) Describe the slope, or steepness, of the distance versus time graph each second (1.00 s, 2.00 s, 3.00 s, and so on) during Lewis’s record run.
