This experiment we will illustrate the forces applied to a body of mass and the resulting acceleration that are proportional to each other. There will be a cart/glider (209g) on an air track attached to a pulley at the end of the air track with a string attached to a weight hanger (5g) as a driving force. Two photocell will be placed at 1m apart to keep track of time.The clock will start one the cart/glider passes by the first photocell and stop and it passes the second photocell. We will repeat this process with 5, 10, 15, 20, 25 and 30 grams added to the weight hanger and while subtraction 5, 10, 15, 20, 25 and 30 grams to the cart/glider.

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.
