Question

What are fundamental units and derived units

Answer 1

=> Fundamental quantity : quantities which are independent on other physical quantity .

Ex: length,mass,time, current, amount of substance, luminous intensity, thermodynamic temperature,

=> Derived quantity : quantities which are depend on fundamental quantities.

ex: Area, volume, density, speed, acceleration, force, velocity etc.

Fundamental units : units which are used to measure the fundamental quantities are called fundamental units.(units which are independent on other units)

ex : meter, time, kilograms, mol, candella, kelvin, ampere

Derived units: units which are derived from fundamental units are called derived units.(units which are dependent on other units i.e fundamental units).

Answer 2

$hey \: there \:$

$\bf fundamental \: units$ : units which are used to measure the fundamental quantities* are called fundamental units.(units which are independent on other units)

ex : meter, time, kilograms,mol,candella, kelvin,ampere

$\bf \: derived \: units$ : units which are derived from fundamental units are called derived units.(units which are dependent on other units i.e fundamental units).

ex:cubic meter, kilogram/cubic meter etc

$\bf \boxed {extra \: info}$

* $\bf \: fundamental \: quantities$ : quantities which are independent on other physical quantity .

ex: length,mass,time, current, amount of substance, luminous intensity, thermodynamic temperature,

$\bf \: derived \: quantities$ : quantities which are depend on fundamental quantities.

ex: Area, volume, density, speed, acceleration, force, velocity etc.
