How are they related to fundamental quantities?​

Answer 1

Hello.

-Why are density and force derived quantities?

Density and force are derived magnitudes because they are formed from fundamental magnitudes. Then, derived magnitudes are a combination of fundamental magnitudes.

-How are they related to fundamental quantities?​

A fundamental unit is a unit adopted to measure a base quantity. A base quantity is one of a subset of conventionally chosen physical quantities, where no subset quantity can be expressed in terms of the others.

Length (meter)

Mass (kilogram)

Time (second)

Electric current (amps)

Thermodynamic temperature (kelvin)

Amount of substance (mole)

Light intensity (candela)
