Specific Relative Angular Momentum - Definition

Definition

Specific relative angular momentum, represented by the symbol, is defined as the cross product of the relative position vector and the relative velocity vector .

where:

  • is the relative orbital position vector
  • is the relative orbital velocity vector
  • is the total angular momentum of the system
  • is the reduced mass

The units of are m2s−1.

For unperturbed orbits the vector is always perpendicular to the fixed orbital plane. However, for perturbed orbits the vector is generally not perpendicular to the osculating orbital plane

As usual in physics, the magnitude of the vector quantity is denoted by :

Famous quotes containing the word definition:

    “The definition of good prose is proper words in their proper places; of good verse, the most proper words in their proper places. The propriety is in either case relative. The words in prose ought to express the intended meaning, and no more; if they attract attention to themselves, it is, in general, a fault.”
    —Samuel Taylor Coleridge (1772–1834)

    “Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.”
    —The Columbia Encyclopedia, Fifth Edition, the first sentence of the article on “life” (based on wording in the First Edition, 1935)

    “... we all know the wag’s definition of a philanthropist: a man whose charity increases directly as the square of the distance.”
    —George Eliot [Mary Ann (or Marian)
