Force
From Newton, force can be defined as an exertion or pressure which can cause an object to move. The concept of force is used to describe an influence which causes a free body (object) to accelerate. It can be a push or a pull, which causes an object to change direction, have new velocity, or to deform temporarily or permanently. Generally speaking, force causes an object's state of motion to change.

Famous quotes containing the word force:
“In the capsule biography by which most of the people knew one another, I was understood to be an Air Force pilot whose family was wealthy and lived in the East, and I even added the detail that I had a broken marriage and drank to get over it.... I sometimes believed what I said and tried to take the cure in the very real sun of Desert D’Or with its cactus, its mountain, and the bright green foliage of its love and its money.”
—Norman Mailer (b. 1923)
“If we wish to know the force of human genius, we should read Shakespeare. If we wish to see the insignificance of human learning, we may study his commentators.”
—William Hazlitt (1778–1830)
“This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy. And also the only real tragedy in life is being used by personally minded men for purposes which you recognize to be base.”
—George Bernard Shaw (1856–1950)
