propulsion theory

Propulsion theory explains how vehicles like ships, airplanes, and spacecraft generate thrust to move through their environment. It involves converting energy into a force that pushes or pulls the vehicle forward. For example, engines burn fuel to produce hot gases expelled rapidly, creating a reactive force that propels the vehicle in the opposite direction (like a rocket). In ships and airplanes, different methods such as propellers or jet engines accelerate air or water to generate thrust. Overall, propulsion theory studies these processes to optimize efficiency, power, and control for transportation and exploration.
