Happy and Sad balls: Qualitative Testing Experiment
Aim
To use your model of momentum conservation to explain the outcome of the following experiment.
Prior Knowledge
- Elastic and inelastic collisions
Description of the Experiment
Watch the first video and observe the differences between the two balls ("happy" and "sad"). Then watch the second video and explain what happens to the plank due to the collision with the "sad" ball. Then use your model of momentum conservation during elastic and inelastic collisions to reason whether the "happy" ball in the third experiment is going to change the momentum of the plank more or less than the "sad" ball. Use your reasoning to predict what might happen to the plank as the result of the collision with the "happy" ball. Write down your prediction. Then watch the last experiment and decide whether your reasoning was supported.
