The graph on the left displays the relation of kinetic energy and the ball's position on the ramp. The graph was based on the data gathered from an experiment where different mass balls are placed on different positions on a ramp. The graph shows as the height of the ball decreases the kinetic energy also decreases. Making a graph using Excel is much better compared to making a manual graph, it is faster and possibly more accurate compared to making a graph manually. |
For the rocket experiment I think the rockets will be launched by pressurising the rockets. If the rockets are launched by pressure than it will demonstrate how pressurised air is acting as potential energy and when it is released the potential energy is changed to kinetic energy because the pressure when released will cause the rocket to move.
