Thrust
Thrust explained in an easy to understand way:
Imagine trying to push a heavy shopping cart with a stuck wheel through the aisles of a grocery store. Just as you exert force to overcome the resistance and move the cart forward, an aircraft or rocket engine produces thrust to propel itself through the air. In both cases, the effort applied to move an object from one place to another is akin to the thrust, where your pushing force is like the engine's power, the cart is like the aircraft, and the friction from the wheel is similar to air resistance.
Practice Version
Thrust: The pushing force exerted by the engine of an aircraft or rocket. Thrust is the force that moves a vehicle forward through air or space.
