Potential Theory is a branch of theoretical physics that deals with phenomena having to do with attraction or the distribution of physical effects through space. It has additionally grown to be a lucrative branch of Mathematics as well, but the context of the information available on this page is confined to a physical interpretation involving the discussion of mutual Newtonian Attraction, i.e., gravitational attraction. Many other interesting applications of potential theory can be made in the areas of electromagnetism, heat propagation and nuclear physics.

The content found on this page largely deals with the classical theory involved. Potential theory is applied in studies of the gravitational attractions of the Earth and other terrestrial planetary bodies. Physical geodesy, a subdiscipline of geophysics, relies heavily on concepts arising in potential theory. The gravitational attraction of stars, galaxies and other large-scale celestial bodies is more properly treated in a study of astrophysics, which is not included on this web site.
