the equations of uniform acceleration for the X and Y motion, and is taken as the acceleration due to gravity at the distance g R from the center of the Earth, the orbital velocity, for a circular vorb orbit can be determined from the time to fall the distance t sy (9a) The orbital velocity can also be calculated by equating the gravitational force to the centripetal force (9b) where the mass of the Earth is = 5.981024 kg. Therefore, the ME greater the radius of the circular orbit, the smaller the orbital R velocity . The period for the circular orbit is T
