Note You create a new physical quantity from the seven basic SI quantities, with an integer exponent. The seven basic SI quantities are length, mass, time, current, thermodynamic temperature, amount of substance, and luminous intensity. For example, the surface consists of the length with the ...
When the interaction of the physical quantities and the unit prices of a given commodity is marked by regularities over time, whether in the recurrence of cyclical or seasonal patterns or in the persistence of secular relations, it is convenient to define the differential movement of quantity with...
The manifoldness with which the fundamental units of time, length, and mass are involved in determining the units of other physical quantities. The magnitude of something in a particular direction (especially length or width or height) A construct whereby objects or individuals can be distinguished...

2. Law of Homogeneity: According to this principle, only those physical quantities that have the same dimensional formula can be compared, equated, added, or subtracted. This is crucial in ensuring that the mathematical operations performed on these quantities are valid. 3. Example to Illustrate ...
Although there are many other types of vectors we will concentrate on vectors of two or three dimensions, called spatial or geometrical vectors, used to represent physical quantities in space. Many of the ideas in this chapter are only true for geometrical vectors of two and three dimensional. ...

Further, the notation a ∨ b is used for the maximum of two quantities a, b > 0. Finally, we mention that in the formulation of Theorem 1.3 as well as below, we assume smoothness of the involved potentials , only for convenience. In all cases, one can derive results for potentials ...
