The purpose of this lab is to experiment with the concept of kinetic energy of rotation and the moment of inertia associated with objects that have very different mass distributions . The procedure for this lab is as follows. 1) Using just the holder and the setup find the amount of weight that it will take to cause the holder to spin at a constant rate. 2) This weight is used to help compensate for the loss of energy due to friction. Take another weight and attach it to the end of the string this weight should be roughly ten times the amount of the weight used to compensate for friction and energy loss. 3) With the two weight at least a meter high let it go and measure the amount of time it takes for the weights to hit the ground. Repeat 19 more times 4) Place the disk on top of the holder. Find out the amount of weight it will take to cause the disk to spin at a constant rate. This will be the weight to compensate for friction and loss of energy for the disk.
