AngularMomentum
type: Class
subclass of: Momentum
subclass of: Restriction
  has value: kilogramRadianPerSecond
  on property: hasDefaultUnit
comment: In physics, the angular momentum of an object rotating about some reference point is the measure of the extent to which the object will continue to rotate about that point unless acted upon by an external torque. In particular, if a point mass rotates about an axis, then the angular momentum with respect to a point on the axis is related to the mass of the object, the velocity and the distance of the mass to the axis. While the motion associated with linear momentum has no absolute frame of reference, the rotation associated with angular momentum is sometimes spoken of as being measured relative to the fixed stars.

PotentialVorticity
type: Class
subclass of: AngularMotionProperty
subclass of: PhysicalQuantity
comment: The vertically averaged vorticity of a layer divided by layer thickness.

RelativeVorticity
type: Class
subclass of: Vorticity
comment: The vorticity as measured in a system of coordinates fixed on the earth's surface. Usually, only the vertical component of the vorticity is meant.

Absolute Vorticity
type: Class
subclass of: Vorticity
