The jet force is a rocket-like force due to Newton's third law which states that for every action there is an equal and opposite reaction. The backward moving exhaust of a burning fuel pushes a rocket or jet forward. It means that throwing a brick off the back of a child's wagon also would push the wagon forward.
Famous quotes containing the words jet and/or force:
“I cannot beat off
Invincible modes of the sea, hearing:
Be a man my son by God.
He turned again
To the purring jet yellowing the murder story,
Deaf to the pathos circling in the air.”
—Allen Tate (1899–1979)
“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)
