Do thrusters work?

Have you ever wondered how spacecraft achieve their speed and direction in space? The answer lies in the use of thrusters. But do thrusters really work? Let's delve into the mechanics behind them. Thrusters are devices that emit a force, usually in the form of a jet of gas or plasma, to propel a spacecraft. This force is generated by igniting a fuel source, such as liquid hydrogen and oxygen, which produces a high-speed exhaust that pushes the spacecraft in the opposite direction. However, does this process actually work to propel spacecrafts through the vast emptiness of space? Join me as we explore the physics and engineering behind thrusters and find out if they truly do work.
