Derivable from the Vis-Viva Equation, if it is measured in kilometers per second, it is about 2.4 for the Moon and about 11.3 for the Earth. It can be found by setting the kinetic energy for an object
Derivable from the Vis-Viva Equation, if it is measured in kilometers per second, it is about 2.4 for the Moon and about 11.3 for the Earth. It can be found by setting the kinetic energy for an object equal to its gravitational potential energy, or as the square root of 2 G M over R. Elliptical orbits result for objects that do not achieve it, while those that exactly match it follow a parabolic trajectory.  Hypothesized to be infinite at the event horizons of black holes, FTP, name this term for the velocity necessary to overcome the gravitational pull of a body.
