Physical Quantities

 Physical Quantities: A physical quantity is a physical property of material or system that can be quantified by measurement. A physical quantity can be expressed as a value, which is algebraic multiplication of a numerical value and a unit.    

Physical quantities are classified into two categories:

Fundamental quantities
Derived physical quantities.

Fundamental Physical Quantities: Physical quantities which cannot be explained by other physical quantities are called fundamental physical quantities.

There are seven fundamental physical quantities listed in the table:

Derived Physical Quantities: Physical quantities which are explained on the basis of fundamental physical quantities are called Derived physical quantities.
