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.

2. Record the results from step one of the experiment (dropping the objects in the air):
First trial:
Second trial:
Third trial:

What law energy has never been broken

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
