Paul Sanders Phys 141 Sect. 16 Newton’s Second Law of Motion Lab- Part III Goals: The goal of this experiment is to investigate another part of Newton’s second law of motion, the acceleration that occurs during uniform circular motion. Theory: The major theory of this lab is Newton’s second law, which states that the force that acts upon an object is equal to that objects’ mass multiplied by its acceleration. By determining whether or not acceleration and mass are proportional, we are able to find the mass of an object being spun in a circle. To find the mass of an object, one must graph the centripetal acceleration against the force, and then divide one by the slope. Qiii. = = a c2p2r Procedure: The equipment in this lab consisted of a circular motion apparatus, a mass hanger and mass set, a ruler, and a stop watch. In the experiment, we set the circular motion apparatus to a given radius by positioning a bobber over a pointer, then attached a spring to the bobber, spun the apparatus until the velocity that produced the original radius was found, and measured the
