Q A1. The following is the distance-time table of an object in motion:
Time in seconds | Distance in metre |
0 | 0 |
1 | 1 |
2 | 8 |
3 | 27 |
4 | 64 |
5 | 125 |
6 | 216 |
7 | 343 |
(b) What do you infer about the forces acting on the object?
i)Velocity is the change in distance with time. So the velocity is increasing non uniformly, so the acceleration increases with the time.
ii) Thus the net force acting on the body is also increasing.
