## angular momentum

n.

2. The vector sum of the angular momentums of each infinitesimal component particle of an extended body.

## angular momentum

n
(Mathematics) a property of a mass or system of masses turning about some fixed point; it is conserved in the absence of the action of external forces

## an′gular momen′tum

n.
the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis.
[1870–75]

## an·gu·lar momentum

(ăng′gyə-lər)
A quantity used to measure the motion of a body that is moving in a circle. The angular momentum depends on the mass and velocity of the body, and on the radius of the circle that it is moving along. Because the velocity of a body moving in a circle is always changing (since velocity is speed and direction), its angular momentum is also always changing.
