Force

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.

    It recognizes no morality but a sham morality meant for deceit, no honor even among thieves and of a thievish sort, no force but physical force, no intellectual power but cunning, no disgrace but failure, no crime but stupidity.
    Woodrow Wilson (1856–1924)

    I was not long since in a company where I wot not who of my fraternity brought news of a kind of pills, by true account, composed of a hundred and odd several ingredients; whereat we laughed very heartily, and made ourselves good sport; for what rock so hard were able to resist the shock or withstand the force of so thick and numerous a battery?
    Michel de Montaigne (1533–1592)
