Abstract

A physics equation is a symbolic representation of physics knowledge through mathematical modeling. The equation is a medium that links physics with mathematics, making necessary a teaching and learning approach in which physics equations can be used to provide a way of understanding physics concepts beyond their use as a simple tool of physics problem solving. This study provides a hierarchical analysis at three levels on the meanings of physics equations. In the process, the difference between physics equations and mathematics formulae, and the difference between the physical meanings and the mathematical meanings of physics equations are analyzed. In particular, the physical meanings of the equations are analyzed and synthesized in ontological and epistemological dimensions. The framework and the results of this study may provide a foundation for more meaningful teaching and learning of physics equations.

Keywords: Physics equation, Physical meaning, Mathematical meaning, Ontological category, Epistemological category
