Centripetal Force Victor Liou Partner: Brian Kelly March 05, 2008 Centripetal Force Abstract: In this experiment, I found the relationship between mass, velocity, radius of curvature, and force of an object moving in a circular path. The apparatus used allow us to relate centripetal force, acceleration and angular velocity while maintaining a constant mass and radius. By testing five different centripetal forces, I was able to find five different periods of rotation and five angular velocities. The equations that I utilized to relate and show validity in my data were: = , = , F ma Fc mv2r and = Fc mrω2 . I found that = . mr 0 082N which fit in my range of the slopes of my two worst error bars 0.0738<0.082N<0.0921. Theory: Force is required to change an object’s velocity through changes in acceleration. In this experiment, we will investigate the force that is necessary to keep an object moving in uniform circular motion, or a path that is a perfect circle at a constant speed. We know that speed is magnitude of velocity. We also know that there is a force exerted on an object in uniform circular motion since its velocity vector is changing direction as time goes on. The acceleration of an object in uniform circular
