Question

please help! medal and fan!

Answer 1

Part one: The Lab
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:


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

First trial:

Second trial:

Third trial:


Record the results from step two of the experiment (dropping the objects in a vacuum):

First trial:

Second trial:

Third trial:

Did the experiment support your hypothesis? Using the data from your experiment, describe why you believe your hypothesis was either proven or disproven.


What forces were acting on the objects dropped in the air? What force was acting on the objects dropped in the vacuum?


Part two: Comparing Forces
Choose two forces and compare and contrast these forces. You must provide two ways that they are alike and two ways that they are different. You may make a list, write in paragraph form, or make a chart.


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.

Answer 4

hello and ok :D

Answer 5

Vacuum is the absence of air, of course. Let's conduct a thought experiment. Suppose we have 2 tubes 100 feet, both absolutely vertical, one with air in it and the other emptied of air. Now I drop two identical tennis balls into the top of each tube at the same time. Which tennis ball hits the ground first, the one in air or the one in the tube where there is no air? Intuitively, we would expect the one dropped in the vacuum to hit first because there would be no air resistance against the tennis ball.Vacuum means that the container or space is empty---there is no air. That is key. If you drop objects in air, there is both the force of gravity acting as well as air resistance. There is no air resistance in vacuum (so just gravity is acting on the object). That is why they say that in the absence of air objects fall at the same rate. Air resistance doesn't matter much for something like a bowling ball but it would for an object like a feather.

Neglecting air resistance, objects fall at the same rate because the acceleration due to gravity it identical for all objects near the surface of the Earth. The force is not the same (you would probably prefer having a feather dropped on you rather than a bowling ball!) but the acceleration is the same.

Does that answer your question?
