Thrust
What is it?
Thrust is the force that moves objects forward. Without thrust, we would never go anywhere! Thrust is also the opposite force to drag, which tries to keep objects from moving forward.
Give me an example!
Have you ever thrown a dart or paper airplane? The force imparted on the dart or airplane by your arm is thrust that moves it forward. In aircraft and rockets, thrust is provided by the backdraft of a turning propeller or by the pressure created by superheated gasses escaping from the combustion chamber of a jet engine. After lift makes an aircraft airborne, thrust is what moves it through the air like when you throw a paper airplane. In most aircraft, the direction of thrust is controlled by flaps called rudders and ailerons.
