Earth gravitational constant km
WebThe force on an object of mass m1 near the surface of the Earth is. F = m1g. This force is provided by gravity between the object and the Earth, according to Newton’s gravity formula, and so you can write. The radius of the Earth, re, is about 6.38 × 10 6 meters, and the mass of the Earth is 5.98 × 10 24 kilograms. http://www.vaporia.com/astro/start/standardgravitationalparameter.html
