Potential


Definition:

  • (a.) Being potent; endowed with energy adequate to a result; efficacious; influential.
  • (a.) Existing in possibility, not in actuality.
  • (n.) Anything that may be possible; a possibility; potentially.
  • (n.) In the theory of gravitation, or of other forces acting in space, a function of the rectangular coordinates which determine the position of a point, such that its differential coefficients with respect to the coordinates are equal to the components of the force at the point considered; -- also called potential function, or force function. It is called also Newtonian potential when the force is directed to a fixed center and is inversely as the square of the distance from the center.
  • (n.) The energy of an electrical charge measured by its power to do work; hence, the degree of electrification as referred to some standard, as that of the earth; electro-motive force.

Example Sentences:

  • (1) Intrathecal injection of zopiclone potentiated morphine antinociception, while the intracerebroventricular injection of zopiclone failed to enhance morphine antinociception and the intracerebroventricular injection of flumazepil to antagonize the intraperitoneal-zopiclone-induced increase in morphine antinociception.
  • (2) Fibulin is a potential mediator of interactions between adhesion receptors and the cytoskeleton.
