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:
“Gimme the Plaza, the jet and $150 million, too.”
—Headline, New York Post (Feb. 13, 1990)
“...here he is, fully alive, and it is hard to picture him fully dead. Death is thirty-three hours away and here we are talking about the brain size of birds and bloodhounds and hunting in the woods. You can only attend to death for so long before the life force sucks you right in again.”
—Helen Prejean (b. 1940)
