Define Derived Quantity with Example

Answer : Derived quantities are mainly physical quantities. The actual quantities are length, current, mass, time, intensity, luminous, etc. It must be derived mathematically from the fundamental quantities. For example, force is a type of derived quantity. For this reason, the dimension and the force must be expressed in terms of basic quantities such as length (L), Mass (M), and time (T).

Many quantities cannot be directly measured, and few can be calculated in physical science. Volume and area are examples of the physical amount derived. It is mainly used for doing calculations of the occupied substances.
