The basic idea of continuum mechanics is that the evolution of a physical system is completely determined by conservation laws, i. e. basic properties such as mass, momentum, and energy are conserved during the considered process at all times. Any physical system can be completely determined by this conservation properties. In contrast, other quantities such as pressure or entropy do not obey conservation laws. The only additional information concerns the consistence of the material (e. g. fluids, solids, porous medium) in form of constitutive laws.
