Question

Give five differences between fundamental quantity and derived quantity.

Answer 1

The difference between fundamental quantity and derived quantity

Sr	Fundamental Quantity	Derived Quantity
1	Fundamental quantities are those that have no reliance on any other physical quantity for their measurement.	A derived quantity is the sum, the products and/or ratios of the fundamental quantities in a system of units.
2	These quantities cannot be reduced any further to their simplest form.	These figures can be reduced to their most basic form, which is made up of fundamental components.
3	In the Metric System or SI system, there are just seven fundamental units.	In the Metric System, there are a vast number of derived units.
4	Examples of fundamental quantities are time $(second,s)$, length $(meter,m)$, mass $(ki\log ram,kg)$, electric current $(ampere,A)$, etc.	Examples of derived quantity are heat $(joule,J)$, power $(watt,W)$, density $(kg/m^3)$, velocity $(m/s)$, etc.
