Explanation:
Detailed explanation-1: -A spin is accomplished by the skater rotating on the part of the blade that is just behind the toe pick. Skaters can perform different types of spins depending on the position of the skater’s arms, legs, and body. Spins fall into three different categories: upright spins, sit spins and camel spins.
Detailed explanation-2: -Spinning While Skating 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.
