Thrust is a force used to propel an object by expelling gas molecules at high speeds.[1] These molecules are what causes the object, such as a rocket, to accelerate. The gas is expelled because an engine or turbine does work on it, sending it to the rear of the engine; this generates thrust in the opposite direction of the moving gas (see Figure 1).[2]
Visit NASA to learn more about thrust and different propulsion systems.
Figure 1. The concept of thrust works because of Newton's 3rd law—every action has an equal and opposite reaction.[3]
