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:
“Rich are the sea-gods:Mwho gives gifts but they?
They grope the sea for pearls, but more than pearls:
They pluck Force thence, and give it to the wise.
Every wave is wealth to Daedalus,
Wealth to the cunning artist who can work
This matchless strength. Where shall he find, O waves!
A load your Atlas shoulders cannot lift?”
—Ralph Waldo Emerson (1803–1882)
“The difference between a photograph and even the most realistic painting—say, one of Courbet’s landscapes—is that in the latter there has been selection, emphasis and some discreet distortion. The painter’s deep instinctive feeling for mass and force has rearranged everything.”
—Gerald Branan (1894–1987)
“Collective guilt is borne by what is conventionally called the scapegoat. Now the scapegoat for white society—which is based on myths of progress, civilization, liberalism, education, enlightenment, refinement—will be precisely the force that opposes the expansion and the triumph of these myths. This brutal opposing force is supplied by the Negro.”
—Frantz Fanon (1925–1961)
