... When we want to calculate the acceleration of a body subject to a force we use Newton’s second law, Fnet = ma. To find the angular acceleration of a body subject to a torque we use the rotational equivalent to Newton’s second law which is net = I. The quantity I is called the moment of inertia of ...
