To summarize the car’s velocity information, let the horizontal axis represent time , and the vertical axis represent velocity . The velocity is constant wherever the slope of the distance-vs-time graph is constant. The velocity changes only when the distance graph’s slope changes.

In the graph shown, is the velocity constant for any time interval? a) Yes, between 0 s and 2 s. b) Yes, between 2 s and 4 s. c) Yes, between 4 s and 8 s. d) Yes, between 0 s and 8 s. e) No, never. The velocity is a constant value between 0 s and 2 s. The velocity is not changing during this interval, so the graph has a zero (flat) slope.
