Scalar

Description

A scalar is a pysicochemical quantity that is fully described by its magnitude. A potential difference, differences of concentration or pressure are scalars, whereas a potential gradient is a vector. Similarly, the protonmotive force and metabolic oxygen flux are scalars, whereas the fundamental forces of physics and velocity are vectors.
