Swinging Atwood's machine

A Swinging Atwood's machine is a variant of the traditional Atwood's machine, which is a classic physics experiment used to study dynamics and acceleration in systems involving pulleys and masses. In the standard Atwood's machine, two masses are connected by a string that passes over a frictionless pulley. When the masses differ, one mass will accelerate downwards, and the other will accelerate upwards, allowing for the study of motion under gravity.
