A student investigated the conservation of energy using a simple pendulum. They released a pendulum bob from various heights, hhh, above its lowest point and measured its maximum velocity, vvv, at the bottom of the swing.
The table below shows the results of their experiment.
| Release height hhh (cm) | Maximum velocity vvv (m s−1\text{m s}^{-1}m s−1) |
|---|---|
| 0 | 0.00 |
| 10 | 1.40 |
| 20 | 1.98 |
| 30 | 1.70 |
| 40 | 2.80 |
| 50 | 3.13 |
The student plotted these results on the grid shown in Figure 1 below.
