Fundamental physical quantities are those that are independent of other physical quantities and cannot be defined in terms of other quantities. These include quantities such as length, mass, time, electric current, temperature, amount of substance, and luminous intensity.

Derived physical quantities, on the other hand, are quantities that are defined in terms of fundamental physical quantities. These quantities are derived from combinations of fundamental quantities through mathematical relationships. Examples of derived physical quantities include velocity (defined as distance divided by time), acceleration (defined as change in velocity divided by time), and force (defined as mass multiplied by acceleration).
