What term is defined as mathematical equations based on rules of physics?
I think the term you want is “model” or “mathematical model”? “A mathematical model uses mathematical language to describe a system. Mathematical models are used not only in the natural sciences and engineering disciplines but also in the social sciences; physicists, engineers, computer scientists, and economists use mathematical models most extensively.” http://en.wikipedia.org/wiki/Mathematica… “Mathematical models are of great importance in physics. Physical theories are almost invariably expressed using mathematical models. The laws of physics are represented with simple equations such as Newton’s laws, Maxwell’s Equations and the Schrödinger Equation. These laws are used as a basis for making mathematical models of real situations.” http://en.wikipedia.org/wiki/Mathematica… See also:
