Draw a velocity versus time graph of a stone thrown vertically upwards and then coming downwards after attaining the maximum height.
Explanation:-
When a stone is thrown upwards, it will have an initial positive velocity. This velocity will decrease uniformly due to gravity and become zero at the highest point.
- After that, its velocity will increase its magnitude but in a downward direction. Hence the correct graph of velocity will be as shown:
If we try to draw the graph of speed versus time, it would look like as shown:
