Inside geosync, only if there’s atmosphere to slow it down.
look the moon causes a little bulge on the earth, since the earth turns faster than the moon rotates, the little bulge is always a little ahead of the moon and pulls the moon to speed up giving the moon more energy.
at geosync, the satellite and the bulge it creates stay in line with each other.
at less than geosync, the satellite goes faster than the earth is turning and the satellite is ahead of the bulge. the bulge pulls on the satellite slowing it down until it crashes.
