Specific angular momentum. In celestial mechanics, the specific relative angular momentum (often denoted or ) of a body is the angular momentum of that body divided by its mass. [1] In the case of two orbiting bodies it is the vector product of their relative position and relative linear momentum, divided by the mass of the body in question.
where is the sphere's mass, is the frequency of rotation and is the sphere's radius.. Thus, for example, the orbital angular momentum of the Earth with respect to the Sun is about 2.66 × 10 40 kg⋅m 2 ⋅s −1, while its rotational angular momentum is about 7.05 × 10 33 kg⋅m 2 ⋅s −1.
Orbital position vector, orbital velocity vector, other orbital elements. In astrodynamics and celestial dynamics, the orbital state vectors (sometimes state vectors) of an orbit are Cartesian vectors of position ( ) and velocity ( ) that together with their time ( epoch) ( ) uniquely determine the trajectory of the orbiting body in space. [1 ...
The orbital angular momentum of light ( OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization. OAM can be split into two types. The internal OAM is an origin-independent angular momentum of a light beam that can be associated with a helical or twisted wavefront.

Orbital inclination change is an orbital maneuver aimed at changing the inclination of an orbiting body's orbit. This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector ( delta v) at the orbital nodes (i.e. the point where the initial and desired ...
In quantum mechanics, orbital magnetization, Morb, refers to the magnetization induced by orbital motion of charged particles, usually electrons in solids. The term "orbital" distinguishes it from the contribution of spin degrees of freedom, Mspin, to the total magnetization. A nonzero orbital magnetization requires broken time-reversal ...
NMR coupling or J-coupling. v. t. e. In quantum mechanics, angular momentum coupling is the procedure of constructing eigenstates of total angular momentum out of eigenstates of separate angular momenta. For instance, the orbit and spin of a single particle can interact through spin–orbit interaction, in which case the complete physical ...
