The Concept of Angular Momentum
Angular momentum is a property of rotating objects that helps us understand the speed of rotation and the difficulty of stopping it. By exploring the example of a figure skater, it can be seen that as the moment of inertia decreases, angular velocity increases to conserve angular momentum.
