A body when projected up with an initial velocity u goes to a maximum height h in time t and then comes back at the point of projection. The correct statement is ______________
Figure given below shows a velocity-time graph for a car starting from rest. The graph has three parts AB, BC and CD.
Compare the distance travelled in part BC with the distance travelled in part AB.
A racehorse runs straight towards the north and covers 540 m in one minute. Calculate
- displacement of the horse,
- its velocity in (a) ms−1 (b) kmh−1.
How can you find the following?
Velocity from a displacement – time graph.
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.
An object is thrown vertically upwards. It rises upto a height H and then returns to its initial position. Calculate
The total distance traveled by the object
An object is thrown vertically upwards. It rises upto a height H and then returns to its initial position. Calculate
The displacement of the object.
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 moving with uniform velocity?
Give one example where the displacement is zero but the distance travelled is not zero.
The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero? Justify your answer.
