Abstract The lab of conservation of angular momentum focuses on torque, moment of inertia, angular acceleration to test the law of conservation of angular momentum by observing inelastic collisions between rotating objects. The angular momentum of a particle about an origin is a vector quantity equal to the mass of the particle multiplied by the cross product of the position vector of the particle with its velocity vector. The angular momentum of a system of particles is the sum of that of the particles within it. Angular momentum is a conserved quantity because it stays constant unless external torque is applied to it. In this lab, we use a rotating platform with photogate under an external torque to measure moment of inertia of an object. We drop a mass on the rotating platform to observe conservation of angular momentum. Procedure I. Correction for Systematic Error, i.e., Friction Unlike the motion of the glider on the air track, the rotating table does exhibit significant friction. After starting its rotation, the table will slow down and eventually stop. However, this effect can be taken into account by a preliminary experiment. Set up the computer in MOTION TIMER mode and measure the angular velocity ω of the freely turning table for 20 or
