  Derived quantity & equations • A derived quantity has an equation which links to other quantities. • It enables us to express a derived unit in terms of base-unit equivalent. Example: F = ma ; Newton = kg m s-2. P = F/A ; Pascal = kg m s-2/m2 = kg m-1 s-2

  Derived Quantities. The physical base quantity of a certain kind A can be represented by the multiplication of a number A and the unit quantity of the kind ^a, A = A^a 1. Given the type of base quantity, the choice of the unit is arbitrary; mass m can be in gram, kilogram, or pound. Obviously the the numerical values of the quantity varies ...

  Derived quantities are expressed as algebraic combinations of base quantities. c. A base unit is a standard for expressing the measurement of a base quantity within a particular system of units. So, a measurement of a base quantity could be expressed in terms of a base unit in any system of units using the same base quantities. For

  Physical quantities are of two types: base quantities and derived quantities. The base quantities, which are defined in entirely physical terms, form a complete set of basic building blocks for an open-ended system of “derived” quantities that may be introduced as necessary. The base and derived quantities together provide a rational basis ...

  A physical quantity can be expressed with a unique combination of 7 base quanti-ties. One can also make a physical quantity with a combination of derived quantities. But it will be eventually reduced to a combination of base quantities. For exam-ple, Kinetic Energy (E) is a type of energy represented in joule (J) and is a derived quantity ...
