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:

“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)

“The event combined with
Beams leading up to it for the look of force adapted to the wiser
Usages of age, but it’s both there
And not there, like washing or sawdust in the sunlight,
At the back of the mind, where we live now.”
—John Ashbery (b. 1927)
