Question

The figure given below shows the displacement-time graph for four bodies A, B, C and D. In each case state what information do you get about the acceleration (zero, positive or negative).

Answer

The following information is obtained from the given figures —

A → Zero acceleration since slope (i.e., velocity) is constant.
B → Zero acceleration since slope (i.e., velocity) is constant.
C → Negative acceleration (or retardation) since slope is decreasing with time.
D → positive acceleration since slope is increasing with time.
