Rotational or Angular Motion
... When this skater brings in his arms, he begins to spin faster. He has decreased his radius of rotation, so his moment of inertia is decreased. By the law of conservation of angular momentum, a decrease in moment of inertia means an increase in angular speed. www.youtube.com [Search “one foot spin”] ...
