Gravity Assignment

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

First trial: The big ball fell faster than the small ball

Second trial: The small ball fell faster than the feather

Third trial: The big ball fell faster than the feather

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

First trial: The feather and the small ball hit the ground at the same time

Second trial:The big ball and the small ball hit the ground at the same time

Third trial: The bigger ball and the feather hit the ground at the exact 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. My hypothesis wasnt proven because all the objects regarless of weight and acceleration all hit the ground at the exact same rate and time.

What forces were acting on the objects dropped in the air? What force was acting on the objects dropped in the vacuum? The force acting upon the objects dropped in the air was air resistance and gravity. The force acting upon the objects dropped in the vacuum was gravity only.

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. The strong nuclear is different from the weak nuclear because the strong nuclear holds an atoms nucleus together and a weak nuclear governs nuclear decay and radioactivity.Strong nuclear is the strongest of the four forces where as the weak nuclear is the second weakest of all four forces. There alike because they both have a short range of force and there particles and subatomic particles experience the same force

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.

Gravity is different from electro-magnetism because gravity is the attraction between objects with mass and electro-magnetismis the attraction or repulsion between electrically charged particles. Gravity is the weakest of the four forces and electro-magnetism is the second strongest of the four forces. there alike because they both have infinity range of force and they both attract forces
