A representation of a selected physical system that specifies retained degrees of freedom, laws, parameters, and idealizations; a model can instantiate a theory without being either exact or a controlled approximation.

This is an authored directed relation from the source endpoint to the target endpoint.
A physical model specifies which independent variables or modes it retains.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-physics-degree_of_freedomwp-physics-physical_modelThis is an authored directed relation from the source endpoint to the target endpoint.
A physical model selects a system, degrees of freedom, parameters, boundary or initial data, and often idealizations within or motivated by a theory; not every model is a controlled approximation.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.
