Balloon in a cart: Testing Experiment
Aim
To predict what happens to a balloon in a cart when the cart is pushed forward.
Description of the Experiment
- A helium-filled balloon is attached to a thread and placed inside a clear plastic box. The box is on wheels. Predict what happens to the balloon when Dave pushes the cart forward. Do not play the movie.
- Explain how you made the prediction and write it down. What physics principles did you use?
- Play the movie. Was your prediction correct? If not, what do you need to modify to account for the results of the experiment?
