   Syn: Strength; vigor; might; energy; stress; vehemence;
        violence; compulsion; coaction; constraint; coercion.

   Usage: {Force}, {Strength}. Strength looks rather to power as
          an inward capability or energy. Thus we speak of the
          strength of timber, bodily strength, mental strength,
          strength of emotion, etc. Force, on the other hand,
          looks more to the outward; as, the force of
          gravitation, force of circumstances, force of habit,
          etc. We do, indeed, speak of strength of will and
          force of will; but even here the former may lean
          toward the internal tenacity of purpose, and the
          latter toward the outward expression of it in action.
          But, though the two words do in a few cases touch thus
          closely on each other, there is, on the whole, a
          marked distinction in our use of force and strength.
          ``Force is the name given, in mechanical science, to
          whatever produces, or can produce, motion.'' --Nichol.

                Thy tears are of no force to mollify This flinty
                man.                              --Heywood.

                More huge in strength than wise in works he was.
                                                  --Spenser.

                Adam and first matron Eve Had ended now their
                orisons, and found Strength added from above,
                new hope to spring Out of despair. --Milton.
