View source for Angular vs. Linear Momentum

{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Angular_vs_Linear_Mo.gif}}

A pin connects the large wheel to the shaft. With the pin removed, only the shaft turns as the assembly moves down the ramp. With the pin in place, the large wheel rotates with the shaft. This absorbs much of the energy of the system and causes the assembly to move down the ramp at a much slower rate.
