1. You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. Before you conduct your experiment, you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur.
Record your hypothesis here: If two objects fall at the same height then the object with the greatest mass will fall to the ground first.
2. Record the results from step one of the experiment (dropping the objects in the air):
First trial: A leaf and a large ball, the ball landed first
3. Second trial: the two balls the large one and the small one fell at the same time
4. Third trial: the feather and the small ball the small ball fell first
5. Record the results from step two of the experiment (dropping the objects in a vacuum):
First trial: the two balls the large one and the small one they fell at the same time.
Second trial: the feather and the large ball the ball fell first.
Third trial: the feather and the small ball the ball fell first
6. Did the experiment support your hypothesis? Using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. My experiment didn’t support my hypothesis using the data from my experiment my data was disproven because when the ball fell they dropped at the same time
7. What forces were acting on the objects dropped in the air? What force was acting on the objects dropped in the vacuum? The force that was acting on the objects that dropped in the air was friction. The force that was acting on the object when it dropped in the vacuum was friction also
Part two: Comparing Forces
1. Choose two forces and compare and contrast these forces. You must provide two ways that they are
