Angular momentum, property characterizing the rotary inertia of an object or system of objects in motion about an axis that may or may not pass through the object or system. Learn what angular momentum is, how to calculate it, and how it relates to rotational motion. Explore the angular momentum of electrons, satellites, planets, and more with formulas, examples, and solved problems. Conservation of angular momentum , definition and mathematical expression, practice problems, FAQs You might have gone to the circus and saw the acrobats performing feats. If you’d observe carefully, while performing feats involving spin they bring their arms and legs closer to the body and suddenly they start spinning faster. Ever wondered why it happens? You would have known if you knew about angular momentum conservation. It also answers why earth keeps spinning. Table of contents ...
