Concept explainers
The variation of gravitational acceleration g with altitude y is given by:
where R = 6371 km is the radius of the Earth, and g0 = 9.81 m/s2 is the gravitational acceleration at sea level. The change in the gravitational potential energy, ?U, of an object that is raised from the Earth is given by:
Determine the change in the potential energy of a satellite with a mass of 500 kg that is raised from the surface of the Earth to a height of 800 km.
