Force
In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. It is measured with the SI unit of newtons and represented by the symbol F. In other words, a force is that which can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. Force can also be described by intuitive concepts such as a push or pull. A force has both magnitude and direction, making it a vector quantity.

Famous quotes containing the word force:
“Men have two ways of righting their wrongs, by force and by the ballot. Both are denied to women, one by nature, the other by man.”
—Ida A. Harper 1851–1931, U.S. women’s magazine contributor. Fireman’s Magazine, repr. In The Woman’s Magazine, pp. 423-5 (May 1887)

“Love, the strongest and deepest element in all life, the harbinger of hope, of joy, of ecstasy; love, the defier of all laws, of all conventions; love, the freest, the most powerful moulder of human destiny; how can such an all-compelling force be synonymous with that poor little State and Church-begotten weed, marriage?”
—Emma Goldman (1869–1940)
