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:
“The sure way of judging whether our first thoughts are judicious, is to sleep on them. If they appear of the same force the next morning as they did over night, and if good nature ratifies what good sense approves, we may be pretty sure we are in the right.”
—Horace Walpole (1717–1797)
“In Arms not worse, in foresight much advanc’t,
We may with more successful hope resolve
To wage by force or guile eternal Warr
Irreconcileable, to our grand Foe,”
—John Milton (1608–1674)
“Strange how such innocence gets its own way.
I shouldn’t be surprised if in this world
It were the force that would at last prevail.”
—Robert Frost (1874–1963)
