Force
From Newton, force can be defined as an exertion or pressure which can cause an object to move. The concept of force is used to describe an influence which causes a free body (object) to accelerate. It can be a push or a pull, which causes an object to change direction, have new velocity, or to deform temporarily or permanently. Generally speaking, force causes an object's state of motion to change.

Famous quotes containing the word force:
“The Force is with you, young Skywalker, but you are not a Jedi yet.”
—Leigh Brackett (1915–1978)
“In the new science of the twenty-first century, not physical force but spiritual force will lead the way. Mental and spiritual gifts will be more in demand than gifts of a physical nature. Extrasensory perception will take precedence over sensory perception. And in this sphere woman will again predominate.”
—Elizabeth Gould Davis (b. 1910)
“Love, the strongest and deepest element in all life, the harbinger of hope, of joy, of ecstasy; love, the defier of all laws, of all conventions; love, the freest, the most powerful moulder of human destiny; how can such an all-compelling force be synonymous with that poor little State and Church-begotten weed, marriage?”
—Emma Goldman (1869–1940)
