Appendix E ROCKET THEORY Rocketry encompasses a wide range of topics‚ each of which takes many years of study to master. This chapter provides an initial foundation toward the study of rocket theory by addressing the physical laws governing motion/propulsion‚ rocket performance parameters‚ rocket propulsion techniques‚ reaction masses (propellants)‚ chemical rockets and advanced propulsion techniques. matter‚ which depends on both how much and how fast propellants are used (mass flow rate)

SHAMINMENISHA How Water Rockets Work A water rocket works using the same principles as other rockets. There are three main forces in action: thrust (Fapp)‚ drag (Ffr) and weight (w=mg). The water‚ which is forced out by the difference between internal and atmospheric pressure‚ is a reaction mass that provides the thrust. All rockets have a reaction mass‚ which can vary from hot gasses that are expelled when a fuel is burnt (in the Space Shuttle’s SRB’s for example) to water in a water rocket. The
