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.

“Some sepulcher, remote, alone,
Against whose portal she hath thrown,
In childhood, many an idle stone
Some tomb from out whose sounding door
She neer shall force an echo more,
Thrilling to think, poor child of sin!
It was the dead who groaned within.”
