Meaning of ROCKET in English
Type of jet-propulsion device that uses either solid or liquid propellants to provide the fuel and oxidizer needed for combustion.
The hot gases provided by combustion are ejected in a jet through a nozzle at the rear of the rocket. The term is also commonly applied to any of various vehicles, including fireworks, skyrockets, guided missile s, and launch vehicle s for spacecraft , that are driven by such a propulsive device. Typically, thrust (force causing forward motion) is produced by reaction to a rearward expulsion of hot gases at extremely high speed (see Newton's laws of motion ).
