Tsiolkovsky Rocket Equation

The Tsiolkovsky rocket equation, also called the classical or ideal rocket equation, is a mathematical equation describing the motion of vehicles that follow the basic principle of a rocket: a device that accelerates itself by expelling part of its mass at high velocity and moves as a consequence of the conservation of momentum. It is named for and usually credited to Konstantin Tsiolkovsky, who derived and published it in 1903, though William Moore had outlined it as early as 1810, and Robert Goddard and Hermann Oberth independently obtained the same result in 1912 and 1920 respectively.
