Akshay Patel Period 10 01/15/09 Honors Physics Lab- Rotational Inertia Objective: To determine the moment of inertia of a rotating body from its angular acceleration. Conclusion: Moment of inertia is the measure of an object’s resistance to changes in its rate of rotation. Moment of inertia is found by using the relationships between angular acceleration, linear acceleration, torque and tension. When doing the experiment, a mass was put onto the platter and was set to fall. Using the computer connected to the pulley, it measured the acceleration of the fall weight. To find the moment of inertia in this lab, you use calculations starting from the linear acceleration. The linear acceleration is equal to the angular acceleration times the radius. The radium of the pulley was 0.02 m. Tension is found from the equation T=M (g times a). The hanging mass was 0.105 kg and the gravity is constant 9.8 m/s2. The torque is now found because Torque = Tension times the radius. The radius is 0.02 m and the tension was found earlier. The formula for
