Thrust

Thrust is the force that propels an object forward, typically generated by engines or engines-like devices such as jet engines or rockets. It works by pushing air, water, or gases backward with high speed, creating an equal and opposite reaction that pushes the vehicle ahead according to Newton's third law. This force overcomes resistance like gravity and drag, allowing aircraft, rockets, or missiles to accelerate and maintain their course. In simple terms, thrust is the "push" needed to move and sustain motion in various transportation and aerospace systems.
