Chapter 1 Units, Physical Quantities and Vectors 1.1 Nature of physics Mathematics. Math is the language we use to discuss science (physics, chemistry, biology, geology, engineering, etc.) Dimensions of common physical quantitiesВ¶ Many derived quantities are measured in derived units that have their own name. Force is one example: Newton (N) is a derived unit for force, equal to \(\hbox{kg\, m/s}^2\). Another derived unit is Pascal (Pa) for pressure and stress, i.e., force per area.

PHYSICAL QUANTITIES AND THEIR SI BASE UNITS. Following is the list of Physical Quantities and their SI Base Units and Symbols.

physical quantity.вЂќ The currently available systems of physical quantities and units with their symbols have been described. Physical quantities and their units that are regulated by the SystГЁme International dвЂ™UnitГ©s (SI) have been carefully considered. In order to provide for the unification of units of physical quantities throughout the Each base quantity is considered a dimension denoted by a specific symbol written within square brackets. It stands for the qualitative nature of the physical quantity. For example, different quantities such as length. Breadth, diameter, light year which are measured in metre denote the same dimension and has the dimension of length [ L ].

Some quantities are known as several different names such as the magnetic B-field which known as the magnetic flux density, the magnetic induction or simply as the magnetic field depending on the context. Similarly, surface tension can be denoted by either Пѓ, Оі or T.

Derived Physical Quantities. When a physical quantity expresses itself in terms of two or more fundamental physical quantities. It is derived by multiplying or dividing one basic physical quantity with another basic physical quantity. Examples- density, volume, force, power, velocity, acceleration, etc. International System of Units (SI Units SI Dimensions of Physical Quantities listed by Category compiled by Stanislav SГЅkora, Extra Byte, Castano Primo, Italy 20022.
