Satellites closer to Earth experience a stronger gravitational force than those farther away due to the force of gravity from the Earth.
When a satellite orbits the Earth, the only force acting on it is the force of gravity from the Earth. Satellites closer to Earth experience a stronger gravitational force than those farther away. For example, if two satellites A and B start at unequal distances from Earth, satellite A, being closer to Earth, feels a stronger gravitational force and accelerates more rapidly than satellite B.
