Procedures: In order to demonstrate this phenomenon, we will use the same disk system from the previous lab, combined with a ball catch system attached to the disk, to show how linear momentum is converted into angular momentum, conserved in the system. In order to find the velocity of the ball at the bottom of the ramp, we will use a similar method to lab 111, where we launch the ball off of a ramp, allowing it to hit carbon paper, and using kinematics, to calculate the initial velocity of the ball before leaving the ramp. Setup: Similar to the previous lab, except that now a ball catch has been attached to the rotating disk system, and a ball ramp has been placed so that the ball will travel directly into the ball catch at the end of the ramp....
