#### Transcript of 01.04 Forces in Action

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: two objects of disparate masses fall to the ground in the same time.

Record the results from step one of the experiment (dropping the objects in the air):

First trial:Without the vacuum mode, the big ball hit the ground first. The feather wafted in the air before hitting the ground while the big ball dropped directly to the ground.
Second trial:Without the vacuum mode, the big ball and the small ball both hit the ground at the same time.
Third trial:Without the vacuum mode, the small ball and the feather hit the ground separately; the small ball reached the ground first while the feather wafted around.
Record the results from step two of the experiment (dropping the objects in a vacuum):
First trial: In vacuum mode, both the big ball and feather hit the ground at the same time.
Second trial: In vacuum mode, both the big ball and the small ball hit the ground at the same time.
Third trial: In vacuum mode, both the feather and the small ball hit the ground at the same time
Did the experiment support your hypothesis? Using the data from your experiment, describe why you believe your hypothesis was either proven or disproven.

The experiment supported by hypothesis. In vacuum mode, the dropped objects hit the ground at the same time no matter what their masses were.
What forces were acting on the objects dropped in the air? What force was acting on the objects dropped in the vacuum?

Both air resistance and gravity acted on the forces dropped in the air. Only gravity acted on the forces dropped in the vacuum
Choose two forces and compare and contrast these forces. These must be different forces than used in the prior question. Provide two ways that they are similar and two ways that they are different. You may make a list, write it out, or make a chart.
