$\small \blue {\sf{Answer }}$✨❤

$\small \underline {\sf{Fundamental \ quantities: }}$

The physical quantities which can be treated as independent of other physical quantities and are not usually defined in terms of other physical quantities, are called fundamental quantities.

To give a consistent and unambiguous description to all physical quantities, we need a minimum of 7 fundamental or base quantities.

They are mass, length, time, electric current, temperature, luminous intensity and amount of substance.

$\small \underline {\sf{ Derived \ quantities:}}$

The physical quantities whose defining operations are based on other physical quantities, are called derived quantities.

All physical quantities other than the seven base quantities are derived quantities.

For example, velocity, acceleration, force, momentum etc.
