Show the difference between distance and displacement with the help of a diagram.

उत्तर
In this case Distance travelled = half of the parameter of circle.
So distacne travelled is = πr
Displacement = diameter of circle.
So displacement is 2r

The table below shows the distance travelled by two vehicles A and B during each second:
| Time (s) | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Distance travelled by A (m) | 0 | 20 | 80 | 180 | 240 | 300 | 360 | 420 |
| Distance travelled by B (m) | 0 | 10 | 40 | 90 | 160 | 250 | 360 | 490 |
Which vehicle is ahead at the end of 7th second and by how much?
Displacement / Time : Velocity :: Speed / Time : ______.
Distinguish distance and displacement.
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.
