The speed needed to leave earth's gravity is

WebJun 13, 2010 · Although this is a loss of speed due to gravity, it is not gravity loss. The 25,000 mph initial speed is the speed required to escape the gravity of the Earth-moon system at that point, the "few thousand mph" is the speed required to escape the gravity of the Earth-moon system at that point. You are not losing energy to gravity. WebThe body must have greater energy than its gravitational binding energy. 1 2 m v 2 = G M m R. therefore, v = 2 G M R. As you can see, this velocity is independent of the mass of the body and therefore, the same for all bodies. On putting the values of G, M, R in the expression, we get. v = 11.2 Km/s.
