If you try to plot the formula as function of Ve with fixed V, you'll see that higher Ve yields higher efficiency. Thrust. In rocket problems, the most common questions are finding the change of velocity due to burning some amount of fuel. Multi-stage Rockets, another of Tsiolkovsy's ideas, separate the propulsion into more than one stage, each stage with its independent rocket motor, propellant tanks and pumps or pressurisation systems. Rocket propulsion is of vital importance for space travel and for launching satellites into orbits around the earth.
