A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds?
When is the magnitude of displacement equal to the distance?
Draw displacement – time graph for the following situation:
When a body is moving with variable velocity.
A car travels at a uniform speed of 42 km/h. In 10 minutes, how much distance would it cover?
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 |
Give the value of the velocity at which they are meeting
Displacement / Time : Velocity :: Speed / Time : ______.
______ is the length of the actual path covered by a body.
The displacement is zero when the initial and final positions are ______.
A quantity that has both magnitude and direction is ______.
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.
