the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis.

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.
