Escape Velocity
Escape velocity, abbreviated as \(v_e\), is the minimum velocity required to leave a planet or moon or the minimum velocity to overcome the pull of gravity.

\(\large{ v_e }\) = escape velocity | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
\(\large{ m }\) = mass of the plamet or moon | \(\large{ lbm }\) | \(\large{ kg }\) |
\(\large{ r }\) = radius from the center of mass (plamet or moon) to start point | \(\large{ ft }\) | \(\large{ m }\) |
\(\large{ G }\) = universal gravitational constant | \(\large{\frac{lbf-ft^2}{lbm^2}}\) | \(\large{\frac{N - m^2}{kg^2}}\) |
