Physics to A level, engineering for the love of it.

The equation gives the eventual speed of a rocket in space (no gravity, no aerodynamics) for a given initial speed, structure mass, fuel mass and exhaust velocity. It is a form of the http://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation. As such, I use it as punctuation when I use the expression "it's not rocket science"

Im doing physics a level too! :)
