Classify Quantity Pdf For Free

We consider that all physical quantities should be classified by the kind of numbers and properties of measurement units into three instead of two categories, consisting of dimensional quantities, numerical enumerated quantities, and relative numerical quantities.

It is shown here that five base quantities (and the corresponding five base units) of nature are sufficient to define all derived quantities (and their units) and to describe all natural phenomena. The base quantities (and their base units) are: length (m), mass (kg), time (s), temperature (K) and electric charge (C).

Magnitude (how much) and multitude (how many), the two principal types of quantities, are further divided as mathematical and physical. In formal terms, quantities?their ratios, proportions, order and formal relationships of equality and inequality?are studied by mathematics.

Following are the seven fundamental quantities: Length (metre) Mass (kilogram) Time (second) Electric current (ampere) Thermodynamic temperature (kelvin) Amount of substance (mole) Luminous intensity (candela)

All physical quantities are classified into vectors and scalars.

Physical quantities are classified into two categories: Scalar quantities - The physical quantities which have magnitude but no direction are called scalar quantities or scalars. ... Vector quantities - The physical quantities which possess magnitude as well as direction are called vector quantities or vectors.
