... When a flywheel speeds up, every point of the flywheel moves at increasing speed. Consider a point on flywheel rim, at distance R from the axis of rotation. If the flywheel speeds up from initial angular speed ω1 to angular speed ω2 in time t, then the speed of the point increases from speed u = ω1 ...
