Unformatted text preview: at these two points on the orbit is a n = v 2 where v is the satellites speed and is the radius of curvature of the orbit at the apogee and the perigee. We know from Newtons Universal Law of Gravitation that the normal force at these two points, F n , is F n = GMm r 2 = ma n = mv 2 = 1 = GM r 2 v 2 But, specific angular momentum is h = rv , so that GM r 2 v 2 = GM h 2 = GM h 2 = 1 Combining with the result above, there follows 1 = 1 2 w 1 r A + 1 r P W...
