Question

which are the derived quantities​

Answer 1

Derived unit :-

Any unit which can be obtained by the combination of one or more fundamental units is called derived unit.

Example -

• Area - $m^2$
• Force - $kgms^{-2}$
• Velocity - $ms^{-2}$
• Volume - $m^3$

______________________

Additional Information

There are two types of units :-

• Fundamental units.
• Derived unit.

Info about Fundamental unit.

The units which can neither be derived from one another nor resolved into anything more basic are called fundamental units.

Example -

• Length - m
• Mass - kg
• Solid angle - sr

The Fundamental Quantity is independent Physical Quantity that is not possible to express in other Physical Quanitity. It is used as pillars for other quantities aka Derived Quantities. In Physics, Length, Mass, Time, Electric Current, Thermodynamic Temperature, etc are examples of Fundamental Quantities

$\sf\: Area = {m}^{2}$

$\sf \: volume \: = {m}^{3}$

$\sf \: force = \frac{kgm}{ {s}^{2} }$

$\sf \: pressure = \frac{kg}{( {m}^{2}) }$

The seven fundamental S.I units are:−

metre → for length

second → for time

kilogram → for mass

kelvin → for temperature

ampere → for electric current

candela → for luminous intensity

mole → for the amount of substance.

A derived unit is a SI unit of measurement comprised of a combination of the seven base units. Like SI unit of force is the derived unit, newton or N where N=1 × m × kg /s^2
