Fact Matrix on Instagram: "Angular momentum is a measure of how much rotational motion an object has. According to the law of conservation of angular momentum, if no external torque acts on a system, its total angular momentum remains constant. This principle explains why a spinning ice skater speeds up when pulling in their arms and slows down when extending them. It applies to everything from planets orbiting the sun to toys like fidget spinners. This conservation law is a fundamental part of

The visual narrative captures the subject's struggle to counteract the overwhelming centrifugal force, resulting in a chaotic sequence of flailing limbs and disoriented revolutions before he manages a clumsy dece
