SUMMARY
The weight of a satellite decreases as its altitude increases due to the diminishing gravitational force. At a height of 12.8 * 10^6 m above Earth's surface, the gravitational acceleration (g) is not constant at 9.81 m/s². Instead, it should be recalculated using the formula F = GMm/d², where G is the gravitational constant, M is the mass of the Earth, m is the mass of the satellite, and d is the distance from the center of the Earth to the satellite. This approach provides a more accurate weight calculation for satellites at significant altitudes.
