Lab Report 8:Rotational MotionDaniel VelezSection 024Performed: November 12, 2015Due: November 19, 2015
Objective: To investigate the relationship between torque, moment of inertia, and angular acceleration for a rigid body rotating about a fixed axis and to examine conservation of angular momentum. Description:This lab utilizes the PASCO software with the rotary motion sensor to help us gain experimental data for a super-pulley apparatus that will allow us to experimentally derive values for moment of inertia for various rigid rotating bodies.Theory: The equation of motion for a particle moving in a circle was already derived ina previous laboratory report and so this explanation will pick up with the application of Newton’s 2ndLaw to become the form: Ftan=mrα. By multiplying both sides by r, we can derive r Ftan=m r2α. This quantityr Ftanis called the torque τabout the axis of the circle. The quantitymr2is called the moment of inertia Iof the mass about the same axis. The
