•A very common misconception is that rocket engines need an atmosphere to create
thrust/acceleration (forward movement).
•However, this is not how rocket engines
(solid or liquid) operate.
•Thrust is created using
Netwon’s 3rd law of motion: “When one body
exerts a force on a second body, the second body
simultaneously exerts a force equal in magnitude
and opposite in direction on the first body.”
•In the case of a rocket engine, it’s the
expelled, expanding, hot gases exiting from the nozzle at high velocity, that pushes against and opposite the rocket body, that
creates the acceleration forces.
