Robert Bouthilet Rjb2385 Partner: Wayne Choy Experiment 5: Motion Under a Central Force Introduction When an object moves around a fixed point of revolution that object experiences a central force. According to theory, if an object experiences a central force, then it will have a constant angular momentum with respect to that fixed point unless it is acted upon by a torque. Any force that has to do with a center of rotation does not have torque. This theory of constant angular momentum is related to Kepler’s Second Law. According to Kepler, if an object experiences constant angular momentum when rotating around a fixed point, then the radius of the object will go over equal areas in equal time intervals. When an object moves around a fixed point, the area swept out by the radius is given by the formula A = . 12θr2 In this experiment we will use an air puck on an air table that will be attached to a fixed point and rotated around a fixed point. Then we recorded the movement of the puck using a camera and by using the programs BTV Pro and ImageJ we will be able to find the coordinates the puck goes through and therefore find the area the puck makes. When the area is plotted on a scatter plot, if it forms a straight line then the air puck experiences constant angular momentum. We predict that when we plot the area covered by the puck, we will see a linear relationship and therefore prove that the puck
