WebDec 17, 2011 · In a linear system we saw that work = Fd. In a rotational system torque (t) - which consists of force and radius - replaces force (F), and distance (d) becomes the angle through which the torque acts. This means work = tθ, where θ is the angle. In the case of an electric motor, θ is 360-deg or one complete rotation. WebJun 29, 2024 · Physical units are measures of distances, areas, volumes, heights, weights, mass, force, and energy.
