Summary Detailed notes on Fields(Gravitational and Electric) and Capacitors

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 are stated. Electric Fields Included in these notes are the key definitions (e.g. Electric field strength, electric potential) as well as the equations and explanations for Coulomb's law, electric field strength for different types of field (radial, uniform), and electric potential. There is also a detailed explanation of equipotential surfaces as well as how the work done on a charged particle is related to electric field strength. Capacitors Included in these notes are the key definitions (e.g. Capacitance, relative permittivity) as well as the equations and explanations of the capacitance of a parallel plate capacitor and its permittivity when a dielectric is placed in between the capacitor plates. A thorough analysis of how a dielectric is used to increase capacitance is also given. Furthermore, the various equations for calculating the energy stored across a capacitor are stated. Finally, the theory, equations, and graphs for capacitor charging and discharging are explained.
