The direction of the thrust is normally along the longitudinal axis of the rocket through the rocket center of gravity. But on some rockets, the exhaust nozzle and the thrust direction can be rotated, or gimbaled. The rocket can then be maneuvered by using the torque about the center of gravity. The magnitude of the thrust can be determined by the general thrust equation.
This great rearward force is balanced with an equal force that pushes the jet engine, and the airplane attached to it, forward. Thrust is the force that propels an airplane forward through the air. It is provided by the airplane's propulsion system in this case by a jet engine. Drag is a force acting on all airplanes.
