Draw velocity – time graph for the following situation:

When a body, is moving with uniform velocity.


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

Compare the distance travelled in section BC with the distance travelled in section AB.


A train starting from rest picks up a speed of 20 ms−1 in 200 s. It continues to move at the same rate for the next 500 s and is then brought to rest in another 100 s.

  1. Plot a speed-time graph.
  2. From graph calculate
    (a) uniform rate of acceleration
    (b) uniform rate of retardation
    (c) total distance covered before stopping
    (d) average speed.

From the diagram given below, calculate distance covered by body.

Interpret the following graph:


State whether true or false. If false, correct the statement.
