NARRATIVE
               Atwood's machine, when equipped with equal masses, is used to demonstrate constant velocity. The pulley has very low inertia.

            By adding a small mass to one side, uniform acceleration may be demonstrated. The relative masses on the two sides of the pulley determine the amount of acceleration.
