WebbThe Rocket Equation. The rocket equation relates the three quantities discussed above as: mass ratio = e ^ (delta-v/exhaust velocity), where 'e' is the mathematical constant equal to ~2.72. There ... WebbThe equation and the subsequent expression of the derivative F e x t = d p d t = d d t ( m v) = d m d t v + m a, ( 1) are based on the erroneous idea that the equation F e x t = d p d t ( 2) is valid for systems that lose or gain mass (where F e x t is external force on the system and p is momentum of the system.
