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:
“Who were the fools who spread the story that brute force cannot kill ideas? Nothing is easier. And once they are dead they are no more than corpses.”
—Simone Weil (1909–1943)
“He saw, he wish’d, and to the prize aspir’d.
Resolv’d to win, he meditates the way,
By force to ravish, or by fraud betray;
For when success a lover’s toil attends,
Few ask, if fraud or force attain’d his ends.”
—Alexander Pope (1688–1744)
“what affects our hearts
Is not the exactness of peculiar parts;
‘Tis not a lip, or eye, we beauty call,
But the joint force and full result of all.”
—Alexander Pope (1688–1744)
