Note that G varies with the square of distance. 26,000/4,000 = 6.5 6.5*6.5= 42.25 G at synchonous altitude is 2.3% of 32.2 ft/sec/sec A satellite is always falling. As it moves sideways it keeps missing the earth. Above synchonous altitude, a satellite will be moving backward compared with the earth.
