प्रश्न
A body is moving along a circular path of radius r. What will be the distance and displacement of the body when it completes:
Two full revolutions

उत्तर
Distance travelled is two times the perimeter of cirle.
So distance travelled is =4π r.
Displacement =0 as starting and ending point are coinciding.

Displacement is a…………………… quantity whereas distance is a………………………….
A body travels a distance of 3 km towards East, then 4 km towards North and finally 9 km towards East.
What is the resultant displacement ?
A body is moving in a straight line and its displacement at various instants of time is given in the following table
| Time (s) | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Displacement (m) | 2 | 6 | 12 | 12 | 12 | 18 | 22 | 24 |
Plot the displacement-time graph and calculate
(i) Total distance travelled in the interval 1 s to 5 s.
(ii) Average velocity in time interval 1 s to 5 s.
Define Distance.
Give two differences between displacement and distance.
Draw displacement – time graph for the following situation:
When a body is moving with variable velocity.
Calculate the distance and displacement in the following case:
The graph shows how the velocity of a scooter varies with time in 50 s.
Work out: The distance traveled in 10 s, 20 s, and 50 s.
Displacement / Time : Velocity :: Speed / Time : ______.
Assertion: If the displacement of the body is zero, the distance covered by it may not be zero.
Reason: Displacement is a vector & distance is a scalar quantity.
