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:
“Do not shut up the young people against their will in a pew, and force the children to ask them questions for an hour against their will.”
—Ralph Waldo Emerson (1803–1882)
“America does not concern itself now with Impressionism. We own no involved philosophy. The psyche of the land is to be found in its movement. It is to be felt as a dramatic force of energy and vitality. We move; we do not stand still. We have not yet arrived at the stock-taking stage.”
—Martha Graham (1894–1991)
“Americans have internalized the value that mothers of young children should be mothers first and foremost, and not paid workers. The result is that a substantial amount of confusion, ambivalence, guilt, and anxiety is experienced by working mothers. Our cultural expectations of mother and realities of female participation in the labor force are directly contradictory.”
—Ruth E. Zambrana, U.S. researcher, M. Hurst, and R.L. Hite. “The Working Mother in Contemporary Perspectives: A Review of Literature,” Pediatrics (December 1979)
