Question
Diagram shows a velocity – time graph for a car starting from rest. The graph has three sections AB, BC and CD.

From a study of this graph, state how the distance travelled in any section is determined.

A graph is a straight line parallel to the time axis in a distance-time graph. From the graph, it implies:
Draw the speed-time graph of a body starting from some point P, gradually picking up speed, then running at a uniform speed and finally slowing down to stop at some point Q.

Draw distance-time graph to show:
Increasing velocity
Interpret the following graph:

(i) In speed time graph uniform motion is given by a straight line parallel to x axis so figure (a) denotes the uniform motion.
(ii) In speed time graph motion with increasing speed is shown by straight line with positive slope so figure (c) denotes the motion with speed increasing.
(iii) In speed time graph motion with decreasing speed is shown by straight line with negative slope so figure (b) denotes the motion with speed decreasing.
(iv) In speed time graph motion with oscillating speed is shown by zigzag line so figure {d) denotes the motion with speed oscillating.
Mention the uses of the velocity-time graph.
The area of the velocity-time graph gives the displacement of the body.
