... respect to O by the polar coordinates (r,θ). Any point P in the object can be located relative to the point O with polar coordinates (r, θ). As the object rotates, P follows a circle of radius r. Every other point in the object also follows a circular path, but a path with a different radius. Let us ...

... Skating – Ice-skaters go into a spin with arms outstretched and a fixed amount of L dependent on the torque used to get themselves spinning. (Once spinning, no external torque) If they then draw in their arms, their inertia decreases, so their angular speed increases in order to keep the total momen ...
