Media Hunt 1: Swinging Atwood’s Machine

This is a video of Swinging Atwood’s Machine which consists of two different masses hanging on a string over a pulley.  The string and the pulley are considered massless.  In Atwood’s Machine both the masses only move in one dimension, but in Swinging Atwood’s Machine one mass moves in two dimensions creating the swinging pattern.  The path of movement has a general pattern, but also has a very chaotic pattern as it goes at very different angles each time.  The more you watch the mass the more order seems to emerge, however it is still has sensitivity to initial conditions as the location it begins affects the path greatly.  It also can only be predicted on a general level, such as which direction it will travel next.
