Definition of Angular momentum

1. Noun. The product of the momentum of a rotating body and its distance from the axis of rotation. "Angular momentum makes the world go round"

Definition of Angular momentum

1. Noun. (physics) The vector product that describes the rotary inertia of a system about an axis and is conserved in a closed system. For an isolated rigid body, it is a measure of the extent to which an object will continue to rotate in the absence of an applied torque. ¹

Medical Definition of Angular momentum

1. Momentum involved in the rotation of a body about an axis, conserved as is ordinary momentum (see momentum). Angular momentum is defined as the cross product of ordinary momentum with the position vector running from the axis of rotation to the body whose angular momentum is being determined. Torque is the rate of change of angular momentum with time. (12 Nov 1997)
