Question
The distance-time values for an object moving along straight line are given below:
| Time (s) | Distance (m) |
| 0 | 0 |
| 1 | 1 |
| 2 | 8 |
| 3 | 27 |
Solution
| Time (s) | Distance (m) | Velocity (ms-1)= distance/time | Acceleration (ms-1)= (v-u)/(t2-t1) |
| 0 | 0 | 0 | 0 |
| 1 | 1 | 1 | 1 |
| 2 | 8 | 4 | 3 |
| 3 | 27 | 9 | 5 |
So the object moves with increasing acceleration
