Angular momentum is defined as the product of mass, angular velocity, and radius, represented mathematically as L = m * ω * r. When the radius decreases while keeping angular momentum constant, the angular velocity must increase to compensate, resulting in a higher velocity of the mass along its circular path. This relationship illustrates that a smaller radius necessitates a faster rate of rotation, confirming the conservation of angular momentum, which is measured in units such as gm-cm²/sec or erg-sec in the cgs system.
