Objective : The purpose of this lab experiment was to confirm the legitimacy of Newton’s Laws of Motion. Description : A circular table which has moveable pulleys around a circumference table was set up. The markings around the table identify the angle at which each pulley is set up. A small centering pin is inserted in the middle of the table as well. A small, circular, metallic ring is hung around the centering pin. Separable pieces of string are attached to the ring; each sting attached goes over a specific pulley and then attaches to a specific weight hangar. Weights are placed on the weight hangers to create an equilibrium; that is, the weights on the weight hangers will cause the metallic ring to become centered on the table without the aid of the centering pin. This set up was used for three weight hangers (and thus, three pulleys) as well as four weight hangers. Theory : It is important to realize that to apply Newton’s Laws of motion, an initial reference frame needs to be established. This was first done by apportioning the weight
