Lab 6 Connected Masses 1. Objective : To measure acceleration due to gravity using connected masses. 2. Equipment: A retort stand and clamps, A pulley mounted on ball bearings, slotted weights, meter rule, stop watch, string. 2. Theory: m 1 m 2 Two masses m 1 and m 2 are connected by a string that passes over a pulley. The net force that makes the system accelerates is (m 2 m 1 )g. This is true only if the pulley is completely frictionless. If the pulley offers a frictional force, we need to compensate it by adding a mass m f to m 2 so that a gentle push on one of the masses will make the system move without acceleration. Add a small mass m f to m 2 to make the system move without acceleration. The total mass that is accelerated by the net force is (m 1 + m 2 + m f ) where m f is the mass used to overcome the friction. F net = ma (m 2 – m 1 )g = (m 1 + m 2 + m f )a 3. Method: (i) Open the digital stop clock and keep it on your desk top and minimize it.
