Key to the equation is the fact that the force ... fuel and throwing the exhaust out the back of the rocket. You generate ten times as much thrust when you throw 10kg of exhaust out the back ...

Tsiolkovsky devised a complex equation that revealed the necessary thrust force needed for any given rocket maneuver, and the "specific impulse" — how much thrust is generated per unit of fuel ...

has the highest thrust-to-weight ratio of any rocket engine ever made. Significantly, the Merlin engines—like roughly 80 percent of the components for Falcon and Dragon, including even the ...

In order to keep that top mass stationary (for the whole rocket pendulum thing) the thrust force must also change both in magnitude and in direction of the thrust. So, this is not a normal rocket ...
