प्रश्न
Give an example of a body which covers a certain distance, but its displacement is zero.
उत्तर
Yes, displacement of a body can be zero even if the distance covered by it is not zero. For example, if a body moves in a circle, then displacement of the body in one rotation is zero but the distance covered by it in one rotation = 2πr, where r is the radius of the circle in which the body is moving.

Distance and displacement
Define Displacement.
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.
- Time after which the body is at the initial position,
- Average velocity after 8 s.
Write the SI units for measurement of distance and displacement.
