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:
“We stood talking for some time together of Bishop Berkeley’s ingenious sophistry to prove the non-existence of matter, and that every thing in the universe is merely ideal. I observed, that though we are satisfied his doctrine is not true, it is impossible to refute it. I shall never forget the alacrity with which Johnson answered, striking his foot with mighty force against a large stone, till he rebounded from it, “I refute it thus.””
—Samuel Johnson (1709–1784)
“Making social comment is an artificial place for an artist to start from. If an artist is touched by some social condition, what the artist creates will reflect that, but you can’t force it.”
—Bella Lewitzky (b. 1916)
“The body, what is it, Father, but a sign
To love the force that grows us, to give back
What in Thy palm is senselessness and mud?”
—Karl Shapiro (b. 1913)
