16) Distance is measured by the area occupied by velocity- time graph.
17)Distance- time graph for uniform motion is a straight line while that of non uniform is a curve.
18)When distance time graph is a straight line parallel to time axis ,then the distance of body is at rest , i.e body does not changes its position with time.
19) In uniform, motion in a straight line velocity and speed remains constant but in uniform circular motion , velocity is variable it changes but speed remains constant there is an acceleration of the body.
20) Here., graph is not given.
