How do the x,y,z acceleration vary over time? Why?

They vary for the first graph. The sprinting graph because the x-axis was when I was sprinting to 20 meters. The device in my hand was swinging back and forth,so the x-axis changed because when I was swinging my and up and down the device was also going up and down. This also caused the y-axis to move up and down because of how far back and forth the device in my hand was going. The z-axis was how my hand was pumping hand back and forth. These differed because they are different things entirely.

They vary for the next graph because one of my 3 lines was me hopping. That was a lot more calm and steady than sprinting so my lines stayed a lot closer to zero than the others, but my other three lines the slightly crazy ones were me skipping which the device was in my cargo pocket so it could have been bouncing each time I skipped with each step.

What happens to Force over time? Patterns?

The force for the first graph did almost show how my running actually was. It was very slow and slight in the beginning and then it slowly sped up; this is when my hands were going back and forth the fastest. Then it drastically stopped because I had reached my distance limit this is were my hands stopped going back and forth.

The second force on the second graph was very drastic because when hopping the device was experiencing a lot of gravitational force when going down because I was just hopping up so now the force was being forced upon the object when going down, but when I was skipping the gravity was not as harsh a force. It was still there but not as strong because when hopping you go up fast then down fast, but when skipping there is almost a fluent motion from skipping up to down.

Explain the relationship between Force and Acceleration in your data.

The relationship between is force in our experiments is the amount of force the device is put upon, so the more we sped up or our acceleration increased we put more force into our arms thus the device also feels that force

Compare and Contrast data for each individual.

To be scientifically correct I do not see any comparisons between Alison’s Sprint graph and my graph, but I do see many contrasts. Our x-axis are slightly different because I believe that since I have longer arms than Alison my arms pumped up and down higher. The Y-axis was also different because it looked to me that I pumped my arms farther out from my body than according to Alison’s graph. My z-axis and Alison’s z-axis where also different because I did pump my arms up and down, but Alison did this more often.

For our hopping and skipping graph I do see some very big contrasts. For some reason Alison’s and my z-axes are very different mine is very consistent an hers is all over the place. The x-axis is also different when I jumped I believe that I jumped higher because of the height differences. The y-axis was extremely consistent because when we were skipping and hopping we kept the device very close to our bodies.

If I wanted the graphs to be more consistent I would of used a simulation program on the computer. Used a slightly less sensitive sensor. Now I could use this information to see that acceleration does have many variables and can change very easily.
Problems that occured were that I did go over my distance limit in the beginning and sometimes we forgot to start the sensor.
If I were to use this test in real life I would use it to see the acceleration of an olympic runner.
