* Linear velocity decreases. This is a fundamental principle of orbital mechanics. As the satellite moves further from the Earth (from perigee to apogee), its gravitational potential energy increases. Since the total mechanical energy of the satellite remains constant, this increase in potential energy must be compensated by a decrease in kinetic energy. As kinetic energy is proportional to the square of the velocity, the satellite's linear velocity decreases.
* The rate of change in velocity is not constant. The satellite doesn't slow down at a steady rate. The force of gravity is weaker at apogee, so the deceleration is less pronounced as the satellite approaches apogee.
In summary:
* Perigee: Highest linear velocity (closest to Earth)
* Apogee: Lowest linear velocity (farthest from Earth)
