Angular Momentum
Quantity of rotational motion.
Linear momentum is the quantity obtained by multiplying
the mass of a body by its linear speed. Angular momentum is the
quantity obtained by multiplying the moment of inertia of a body
by its angular speed. The momentum of a system of particles is
given by the sum of the momentums of the individual particles
which make up the system or by the product of the total mass of
the system and the velocity of the center of gravity of the system.
The momentum of a continuous medium is given by the integral of
the velocity over the mass of the medium or by the product of
the total mass of the medium and the velocity of the center of
gravity of the medium.
