Momentum is mass moving with a ziekenhuis certain velocity, and impulse is thrust applied for a given time. Secondly the exhaust particles are commonly moving near the speed of light, so relativistic effects changes the particle's rest mass.

Front side calculates Thrust, thrust Power, propellant Mass Flow, specific Impulse, and Exhaust Velocity. When a stage drops off, the rest of the rocket is still traveling near the speed that the whole assembly reached at burn-out time. What exactly does specific impulse mean?
