# 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.

## Formulas that use Escape Velocity

\(\large{ v_e = \sqrt { \frac{ 2 \; G \; m}{r} } }\) | |

\(\large{ v_e = \sqrt { 2 \; g \; r } }\) |

### Where:

\(\large{ v_e }\) = escape velocity

\(\large{ g }\) = gravitational acceleration

\(\large{ m }\) = mass of the plamet or moon

\(\large{ r }\) = radius from the center of mass (plamet or moon) to start point

\(\large{ G }\) = universal gravitational constant
