Webb14 feb. 2024 · Let’s get back to the spinning figure skater. Given that no outside force is applied, the angular momentum is conserved. When the skater extends her arms or legs, she effectively increases her radius, and thus changes her moment of inertia. Since the angular momentum remains constant, what changes is the angular velocity of the spin. Webb12 feb. 2024 · You've seen it before.
