Dot Product - Physics

Physics

In physics, vector magnitude is a scalar in the physical sense, i.e. a physical quantity independent of the coordinate system, expressed as the product of a numerical value and a physical unit, not just a number. The dot product is also a scalar in this sense, given by the formula, independent of the coordinate system. Examples include:

  • Mechanical work is the dot product of force and displacement vectors.
  • Magnetic flux is the dot product of the magnetic field and the area vectors.

Famous quotes containing the word physics:

    But this invites the occult mind,
    Cancels our physics with a sneer,
    And spatters all we knew of denouement
    Across the expedient and wicked stones.
    Karl Shapiro (b. 1913)

    Mathematics should be mixed not only with physics but with ethics.
    Henry David Thoreau (1817–1862)

    It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.
    —G.C. (Georg Christoph)
