What are Fundamental Quantities?
Fundamental quantities are independent of each other and cannot be expressed in terms of other physical quantities. They are the building blocks of all other physical quantities, which are called *derived quantities* and can be expressed as combinations of the fundamental quantities.
Examples of Derived Quantities:
* Area: Measured in square meters (m²) – derived from length (m) x length (m).
* Velocity: Measured in meters per second (m/s) – derived from length (m) divided by time (s).
* Density: Measured in kilograms per cubic meter (kg/m³) – derived from mass (kg) divided by volume (m³).
