1. The problem statement, all variables and given/known data why a more massive communications satellite doesn't orbit more slowly than a smaller one? 2. Relevant equations 3. The attempt at a solution The larger satellite will have more mass but it will also have a far greater gravitational force acting on it no matter where it is orbiting. These two will cancel each out. So they will freefall at the same rate providing it is the same distance from the planet.
