Using the data given in the table below, keep time on the x-axis and the corresponding velocity on the y-axis, and draw a separate graph for each of the three bodies.
Study each velocity time graph you have drawn and analyse the shape and slope of its line.

Discussion
In the first graph, what are the shape and slope of the velocity time line? Is the body's velocity uniform, or changing at a steady rate?
In the second graph, is the slope between any two points of the line the same or different? What is the relation between slope and acceleration?
Comparing the third graph with the second, what difference did you see in the slope when the velocity changes steadily and when it changes unevenly?
