Question

Describe the motion depicted in the given below graphs. [3 MARKS]

Answer 1

A,B,C : Each 1 Mark

Acceleration is defined as the rate of change of velocity. In graph A, we can see that the slope of the graph is increasing, hence the speed is increasing with time. Thus the graph represents uniform acceleration.

In graph B, the slope is 0 i.e. the speed does not change with time. Hence the acceleration is zero.

In graph C, the slope is negative, hence it has uniform retardation.
