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.
