Dimensionless quantity — In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a pure number, and as such always has a dimension of 1.[1] Dimensionless quantities are widely used… … Wikipedia
Equation of state (cosmology) — In cosmology, the equation of state of a perfect fluid is characterized by a dimensionless number w , equal to the ratio of its pressure p to its energy density rho;: w=p/ ho . It is closely related to the thermodynamic equation of state and… … Wikipedia
Defining equation (physics) — For common nomenclature of base quantities used in this article, see Physical quantity. For 4 vector modifications used in relativity, see Four vector. Very often defining equations are in the form of a constitutive equation, since parameters of… … Wikipedia
Constitutive equation — Many defining equations are in the form of a constitutive equation, since parameters of a property or effect associated matter are characteristic to the substance in question. A large number of other defining equations not specifically… … Wikipedia
