Rotational Motion About a Fixed Axis

This task is similar to the experiment "Sliding Friction" where we used the video motion tracking to investigate the friction between the surfaces of a linearly sliding body and a static surface. In this task, we will investigate friction accompanying rotational motion. A disc will be attached to a shaft and manually rotated. Friction will decelerate the rotating disc. We will record this motion on a high speed camera and investigate some interesting aspects of angular kinematics.
