Figure 1 Equipment
To accomplish to experiment we’ll be using two photocell 1 m apart, an air track, a mass hanger, cart/glider, air supply and a pulley. We will start by having 5g on the mass hanger and 234g on the cart/glider. By turning on the air supply we can find the time it takes the cart to get to the second photocell. We will repeat this process three times to get an average. Then, we will repeat this whole process until the mass hanger weights 30 g and the cart/glider 224g.
