The angular momentum of a single particle about a designated origin is the vector product of the position vector in the given coordinate system and the particle’s linear momentum. Angular momentum is sometimes called Rotational Momentum or Moment of Momentum, which is the rotational equivalent of linear momentum . It is an important physical quantity as it is conserved for a closed system and follows the Law of Conservation of Angular Momentum. 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 ...
