Angular momentum: Is sometimes called Rotational Momentum or Moment

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 rotating objects. Find out the difference between angular momentum and linear momentum , the right-hand rule, and the quantum number. 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. In linear dynamics, the product of mass and velocity gives linear momentum . In rotational dynamics, the angular momentum of a point object is defined as the product of the linear momentum and the perpendicular distance from the axis of rotation. For a stationary spinning object, angular momentum is defined as the product of the moment of inertia and angular velocity. It is a vector quantity and has both magnitude and direction.
