Thrust
Thrust is a force used to propel an object by expelling gas molecules at high speeds.[2] 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.[3]
