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.

Speed versus time for a non-uniform acceleration.
(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.
