Fg (attractive force) = m.g.(R/r)2 (gravity equals)
Fc (centrifugal force) = m.r.w2 (Trying to pull satellite away equals)
Variables ???????? �.
m = mass of satellite
R = radius of earth ; R=6,370 km
r = distance of satellite to the center of the earth
g = acceleration of gravity ; g =9.81 m/s2
w = angular velocity ; w=2pf ; f is the frequency of rotation;
