The angular momentum of a point-like particle with respect to a particular origin is the cross product of its position and kinetic momentum:

This implies that is perpendicular to the plane formed by and .

Form with angular velocity

We can rewrite the above definition with the implicit definition of the angular velocity:

When and are perpendicular

If the position and velocity vectors are perpendicular, then and are parallel:
