Center+of+Gravity

When using the logger pro to insure the accuracy of the data collection in logger pro we made sure that each data point used for the graphs was at the persons hips. This is because that is a persons center of gravity. This is important because we needed a common point to collect the data and the the center of gravity would allow us to collect data with more accuracy. Cooper's center of gravity was just estimated when analyzing the video in logger pro. It's known that the center of gravity in human beings is generally around the hip area. In order to find Cooper's exact center of mass, he would have had to remain in the same position while he was strung up by several different body parts. Not only would this be very painful, but it would also be impossible.
