value of a quantity
value
- Number and reference together expressing magnitude of a `quantity`.
- The number can be complex.
- A quantity value can be presented in more than one way.
- In the case of vector or tensor quantities, each component has a quantity value.
- For example, force acting on a given particle, e.g. in Cartesian components
:math:`(F_x; F_y; F_z) = (−31,5; 43,2; 17,0) N`, where
:math:`(−31,5; 43,2; 17,0)` is a numerical-value vector and :math:`N` (newton)
is the unit, or :math:`(F_x; F_y; F_z) = (−31,5 N; 43,2 N; 17,0 N)`
where each component is a quantity.
