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.
Thrust is the force necessary to move the aircraft forward and lift is the force acting in the upward direction required to keep the aircraft aloft. Opposing thrust is DRAG or the force produced by air resistance.The last force is the WEIGHT of the airplane, the downward acting force, and is produced by gravity.hrust is the force necessary to move the aircraft forward and lift is the force acting in the upward direction required to keep the aircraft aloft.
