... Given: r = 2.1 x 105 m + 6.37 x 106 m
= 6.58 x 106 m
mearth = 5.98 x 1024 kg
Equation: F = ma, now Fg = mg
(We need g at that altitude.)
Fg = Fg
mg = G m1 m2
= (6.67 x 10-11 N m2/kg2)(5.98 x 1024 kg)
(6.58 x 106 m)2
= 9.21 m/s2
Speed of gravity
In classical theories of gravitation, the speed of gravity is the speed at which changes in a gravitational field propagate. This is the speed at which a change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces. In a more physically correct sense, the ""speed of gravity"" refers to the speed of a gravitational wave, which in turn is the same speed as the speed of light (c).
