Thruster

A thruster is a type of propulsion system used in spacecraft, submarines, and some vehicles to maneuver and control movement. It works by expelling mass—usually in the form of gas or water—at high speed in one direction, which creates a reaction force that pushes the vehicle in the opposite direction, according to Newton’s third law of motion. Thrusters can be used for navigation, adjusting altitude, and stabilizing position in space or underwater, making them essential for achieving precise maneuvers in challenging environments.
