where:
Δ v = Change in velocity (m/s)
ve = Exhaust velocity (m/s)
m0 = Initial mass of the rocket (kg)
mf = Final mass of the rocket (kg)
- The rocket is ideal.
- The exhaust velocity remains constant.
- The change in mass is only due to propellant being expelled.
- There is only a single burn without staging or multile engine firings.
