SUMMARY
The gravitational potential energy (U_g) of a rocket 500 km above Earth's surface can be calculated using the formula U_g = -G * (m1 * m2) / r. In this case, the mass of the rocket (m1) is 500 kg, and the mass of the Earth (m2) is approximately 5.972 × 10^24 kg. The distance (r) from the center of the Earth to the rocket is the sum of Earth's radius (approximately 6,371 km) and the altitude (500 km), totaling 6,871 km. This formula allows for precise calculations of gravitational potential energy at significant altitudes.
