# Formula Orbital angular momentum of circular motion Angular momentum    Mass    Radius    Velocity

## Angular momentum

Unit
Orbital angular momentum of a point mass (e.g. a planet) orbiting at a certain orbital velocity at a certain distance from the axis of rotation. The angular momentum vector is perpendicular to the orbital velocity and the radius vector.

## Mass

Unit
Mass of the body moving on a circular path. The greater the mass, the greater the orbital angular momentum.
