Gravitational fields Included in these notes are the key definitions (e.g. Gravitational potential, escape velocity) as well as the equations and explanations for Newton's Law of Gravitation, gravitational field strength(g) for different types of field(radial and uniform), and gravitational potential. There is also a detailed explanation of equipotential surfaces and escape velocity. The different types of uniform satellites (Geostationary, Geosynchronous) are also compared and their uses a...
