Pat Popovits 3/23/08 Phy120 IN Centripetal Force Lab Report I. Introduction In this lab we will observe the motion of an object moving in a circular motion and determine whether our observations conform to the theoretical model. The equation for centripetal force is F c = mv/r . In this experiment m will be the mass of the rubber stopper tied to the end of fishing line, v will be the speed of the stopper as it travels in a circular path, Fc is the centripetal force, and r is the radius of the travel. We will see that the stopper will not travel at the same level as the top of the handle due to the force of gravity. Therefore, the length between the handle and the stopper ( L ) will turn out to be the vector sum of the radius of travel and the displacement of the moving stopper below the top of the handle. Likewise, the weight of the washers ( T ) is the vector sum of the centripetal force and the weight of the stopper.
