Impact Craters Lab

Today in class my lab was impact craters. My partners were Taryn and Amalia.
For our lab, we had to record the width and depth of craters that we made with a small compass ball and flour in a tin pan.
Then, we had to make 2 hypothesis. The 1st question was; how do you think GPE will affect crater depth- directly, inversly or not at all? Why? We said directly, becaue the higher up the ball is and the faster it goes, the deeper the crater would be, because there would be a lot of force coming down. Same goes for the lower the ball is, and the slower it is going.
The 2nd question was; how do you think GPE will affect crater width- directly, inversly or not at all? Why? We said directly and not at all both, because if the ball is droped from an extremely high height, then the crater would most likely have a larger width, because the force of the drop would impacted the flour, and then it would most likely change the space around it to make room for the ball and the air coming down with it. We said not at all, because if the ball was droped from not a very high height (like 10 cm then the GPE would probably not impact the width of the crater as much.
We had to pick 5 different spots on a meter stick, and drop the ball from those spots. We picked: 10 cm, 20 cm, 40 cm, 60 cm, and 80 cm. Then, we used the measurements in 5 GPE = mgh equations.. That gave us the measurement of energy. Then, we plugged that into a KE = 1/2m v2 problem.
This was to figure out the velocity. The velocities and heights were:
height = velocity
10 cm = .626099034
20 cm = .885437745
40 cm = 1.25219807
60 cm = 1.53362316
80 cm = 1.77087549
We took the data 2 times, because the 1st time we got the same depth and width for each height. Then, we talked to Mary Margaret, and she told us to loosen up the flour. So we did, and then the results were a bit different for each height.
