Draw displacement – time graph for the following situation:
When a body is moving with variable velocity.
From the displacement – time graph shown given below calculate:
- Average velocity in the first three seconds.
- Displacement from the initial position at the end of 13 s.

Show the difference between distance and displacement with the help of a diagram.
Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.
Distinguish distance and displacement.
