A physical quantity can be expressed as a value which is the algebraic multiplication of a Numerical value and a Unit For example the physical quantity of mass can be quantified as 323 kg where 323 is the numerical value and kg is the Unit. Understanding Base Quantities And Derived Quantities Introduction To Physics Physics Notes The Unit Other quantities called derived quantities are defined in terms of the seven base quantities via a system of quantity equations. . See Q 12 from Exercise. Weight and mass are technically different quantities. The SI base unit is defined by the mass type. The level or type is the methodology used for taking the measurement. Weight is a force that results from the action of gravity on matter. A base unit also referred to as a fundamental unit is a unit adopted for measurement of a base ...
