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:
“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?”

“As a final instance of the force of limitations in the development of concentration, I must mention that beautiful creature, Helen Keller, whom I have known for these many years. I am filled with wonder of her knowledge, acquired because shut out from all distraction. If I could have been deaf, dumb, and blind I also might have arrived at something.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“A petty bureaucrat always watches his superior’s countenance, just as a boatman trims his sails according to the force of the wind.”
