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. 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 Learn about the definition, conservation, and examples of angular momentum , the rotational analog of linear momentum . Find out how angular momentum depends on the position of the origin, the moment of inertia, and the angular velocity of a body.
