Question

Look at Figure 2. Describe the motion of the object in Graph A

Compare Graphs A and B in Figure 2. At a time of 2 seconds, which graph shows a greater velocity? How do you know?

Answer 1

The graphs show distance versus time data. For graph A, we can say that velocity is constant until it reaches time of 8 seconds. And a constant velocity is again exhibited starting at time 12 seconds. For graph B, the velocity is changing as time pass by since the slope is changing. At time of 2 seconds, graph A has greater velocity since it has a steeper slope.
