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:
“Most new things are not good, and die an early death; but those which push themselves forward and by slow degrees force themselves on the attention of mankind are the unconscious productions of human wisdom, and must have honest consideration, and must not be made the subject of unreasoning prejudice.”
—Thomas Brackett Reed (1839–1902)
“Man always made, and still makes, grotesque blunders in selecting and measuring forces, taken at random from the heap, but he never made a mistake in the value he set on the whole, which he symbolized as unity and worshipped as God. To this day, his attitude towards it has never changed, though science can no longer give to force a name.”
—Henry Brooks Adams (1838–1918)
“The force we use on ourselves, to prevent ourselves from loving, is often more cruel than the severest treatment at the hands of one loved.”
—François, Duc De La Rochefoucauld (1613–1680)
