What is 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.

Famous quotes containing the word force:

    So doth, so is Religion; and this blind-
    ness too much light breeds; but unmoved thou
    Of force must one, and forc’d but one allow;
    And the right; ask thy father which is she,
    let him ask his; though truth and falsehood be
    Near twins, yet truth a little elder is;
    John Donne (1572–1631)

    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)

    Mine ear is much enamoured of thy note;
    So is mine eye enthrall├Ęd to thy shape;
    And thy fair virtue’s force perforce doth move me
    On the first view to say, to swear, I love thee.
    William Shakespeare (1564–1616)
