It draws a parallel with the conservation of linear momentum and emphasizes that angular momentum is conserved along any axis where the net external torque is zero. The lesson then vividly illustrates this principle using the classic example of an ice skater spinning faster when she pulls her arms in, explaining how a reduction in rotational inertia leads to an increase in angular velocity while conserving angular momentum (Ii​ωi​=If​ωf​).\n
