Ответ:
The correct answer is thrust.
Explanation:
The force that moves the rocket up in the air, and via space is termed as the thrust. It is produced by the rocket's propulsion system through the use of third law of motion given by Newton. The thrust in the rocket is a result of the pressures functioning in the nozzle and the combustion chamber.
The passing of the hot exhaust takes place via a nozzle that increases the flow. The thrust generated by the rocket relies upon the rate of mass flow via the engine, the pressure of the nozzle exit, and the exit velocity of the exhaust.
