प्रश्न
A body at rest is made to fall from the top of a tower. Its displacement at different instants is given in the following table:
| Time (in s) | 0.1 | 0.2 | 0.3 | 0.4 | 0.5 | 0.6 |
| Displacement (in m) | 0.05 | 0.20 | 0.45 | 0.80 | 1.25 | 1.80 |
Draw a displacement-time graph and state whether the motion is uniform or non-uniform?

उत्तर
The displacement-time graph is given below:
When we observe the graph, we find, that the displacement-time graph is a curve.
Hence, we can say that the motion is non-uniform.
