angular momentum
angular momentum
Definition
angular momentum
noun
the momentum characteristic of a rotating object; the product of linear momentum and the perpendicular distance from the origin of coordinates to the path of the object: the conservation of angular momentum causes a spinning skater, star, etc. to increase (or decrease) in velocity as the radius is reduced (or increased): symbol, Ω
angular momentum
Usage Examples
Preposition: of
- gas: At the beginning of the calculation the specific angular momentum of the infalling gas is very low.
- beam: We also confirm that any vortex contained within the beam may change sign even when the orbital angular momentum of the beam remains constant.
Converse of object
- spin: Abstract Jones matrices describe the polarization, or spin angular momentum, of a light beam as it passes through an optical system.
- conserve: As a result, to conserve angular momentum, the rate of rotation must increase.
- have: Finally, if the infalling gas has too much angular momentum it cannot form circumstellar disks and all goes into a circumbinary disk.
- possess: We devise an equivalent of the Jones matrix formulation for light possessing orbital angular momentum.
- transfer: ORION produces DWBA ( Distorted Wave Born Approximation ) cross sections for a range of transferred angular momenta.
- store: Madabhushi, S.P.G. , Schofield, A.N. , Lesley, S. A new stored angular momentum ( SAM ) based earthquake actuator.
Adjective modifier
- orbital: We devise an equivalent of the Jones matrix formulation for light possessing orbital angular momentum.
- intrinsic: Spin: The intrinsic angular momentum possessed by fundamental particles - giving the appearance of them ' spinning ' .
- total: As more pairs are broken, the nucleons contribute more single-particle spin to the total angular momentum.
- specific: The destination of the gas depends on its specific angular momentum relative to the binary.
- large: The large angular momentum in this massive disk leads to turbulence and increased interaction of the constituents.
