does the angular velocity increases or the linear velocity increases when the radius of a rotating body from the axis decreases
Conservation of angular momentum is a fundamental principle in physics that states that the total angular momentum of a system remains constant in the absence of external torque.
Angular momentum is a measure of an object's rotational motion, calculated by multiplying its moment of inertia by its angular velocity.
If a system experiences no external torque, the total angular momentum of the system will remain constant, even if individual components within the system may change their angular momentum.
A common example is an ice skater spinning with outstretched arms. When they bring their arms closer to their body, their moment of inertia decreases but their angular velocity increases, resulting in a constant total angular momentum.
Conservation of angular momentum is closely related to the conservation of energy. In a closed system, if there is no external torque acting, the total energy (kinetic and potential) will also remain constant, as energy and angular momentum are interconnected through rotational motion.
