Ananth Bulusu Michael Burket Rotational Motion with Constant Torque Physics 201 Monday 11/23/09 Abstract The constant torque experiment illustrates the moment of inertia in a real life model. The circular motion is carried out by a mass attached to a string around a pulley connected to the circular motion apparatus. The masses conversion of potential energy to kinetic energy supplies the torque for the apparatus to spin. Several trials using different masses were conducted. Using the data, linear acceleration was calculated by the equation a=2h/t^2, and angular acceleration was used using α=4πn/t^2. Introduction The motion of the lab is a result of a mass’s acceleration downward at 9.81 m/s. The force is redirected to the circular motion apparatus, allowing the experiment to have a constant acceleration. The principle illustrated is Newton’s second law, F=ma. The main concern of this

lab is to observe the actual moment of inertia of the apparatus and compare it to the theoretical assumption. Procedure We first recorded the mass of the wing nuts and the threaded rod found by using the laboratory balance, Which the mass of a single nut was 6.35 gram and the mass of the threaded rod was 61gram. We then measure the length of the threaded rod using the rule and it was
