The Effect of Added Mass to the RPM of a Spinning Wheel

We tested how adding mass to a spinning automotive wheel affects the change in RPM. Using a series of pipes, we introduced various amounts of water into a tire spinning at 100 RPMs and then recorded the change in RPM after 60 seconds. We compared three sets of ten trials with three two-sample t-tests. One set of trials had no water, one set had three liters, and the final set had six liters. After evaluating the three t-tests we concluded that adding water effects the change in RPM. We also concluded that the more mass added, the higher the change in RPM.
