* '''Rocket Propulsion''' — The "Acceleration" of a vehicle by the "Ejection" of "High-Speed Mass" (Exhaust) in the "Opposite Direction."
* '''Newton's Third Law''' — "For every action, there is an equal and opposite reaction." (The core principle of rocketry).
* '''Propellant''' — The "Fuel" (Energy source) and "Oxidizer" (Oxygen source) that are "Burned" to create thrust.
* '''Liquid-Propellant Rocket''' — Uses "Liquid Fuel" (like 'Hydrogen' or 'Kerosene') and "Liquid Oxygen" (LOX) kept in separate tanks (e.g. 'SpaceX Falcon 9').
* '''Solid-Propellant Rocket''' — Uses a "Hard, Rubber-like Mixture" of fuel and oxidizer (e.g. 'Space Shuttle SRBs'). They cannot be "Turned Off" once ignited.
* '''Specific Impulse''' (Isp) — The "Efficiency" of a rocket engine: how much "Thrust" it gets from a "Unit of Fuel." (Measured in 'Seconds').
* '''Combustion Chamber''' — The "High-Pressure Room" where fuel and oxidizer "Explode" together.
* '''Nozzle''' (De Laval Nozzle) — The "Bell-shaped Exit": it "Accelerates" the hot gases to "Supersonic Speeds" (see Article 606).
* '''Ion Thruster''' — An "Electric Propulsion" system that "Accelerates" "Ions" (charged particles) at "Extreme Speeds," used for "Deep Space" missions.
* '''Payload''' — The "Cargo" (Satellites, Humans, Telescopes) that the rocket is "Carrying" to its destination.
