GENERAL KNOWLEDGE

Detailed explanation-1: -The units which can neither derived from one another nor resolved into any thing more basic are called fundamental unit. It is independent of any other unit. Any unit which can be obtained by the combination of one or more fundamental units is called derived unit .

Detailed explanation-2: -The metre, kilogram, ampere, and second are the seven fundamental and derived units in physics. It is called a derived unit when derived quantities are expressed in the same unit.

Detailed explanation-3: -The units for the derived quantities are called derived units. They are obtained by taking the product and / or ratios of fundamental units. For example, unit of speed is m/s.

Detailed explanation-4: -Fundamental units are all those units which are independent of any other unit (including themselves). Derived units are all those units which are obtained by multiplying and/or dividing one or more fundamental units with or without introducing any other numerical factor.

Detailed explanation-5: -A derived unit is a unit that results from a mathematical combination of SI base units. Calculations involving derived units follow the same principles as other unit conversion calculations.
