Learn what comes with the Rotational Inertia Demonstrator and how it is a beautiful and engaging investigation of angular motion! Observe the angular acceleration of the apparatus, and investigate the effects of changes in torque and inertia. Simply move the rope to a pulley of a different radius to change the torque, or move the mass on the arm to change the moment of inertia.
