Newton’s second law is a law that relates the force acting on an object, with the acceleration while holding mass constant. In this experiment Force will be described in Newtons (N) which is derived by the following expression: = 1N 1kg∙ms2 Procedure This experiment will use the following pieces of equipment: Atwood pulley, string, a set of masses, weight hanger, and a stop watch. After the initial setup of the Atwood pulley the first step will be to place equal masses on each side to balance the pulley and to pull the string taught. Next, the amount of mass must be recorded as the initial mass of side 1 and side 2 respectively. After recording the masses add two grams to one side of the Atwood Pulley and measure the amount of time (t) it takes the heavier mass to reach the ground in seconds (s) and...
