 Scalar - Wikipedia, the free encyclopedia (861 words) In physics, a scalar is a physical quantity which assumes a single value which is independent of the coordinate system being used to describe the physical system. A vector is a physical entity which has a magnitude which is a scalar, but in addition, in contrast with a scalar, has a direction. The components of a vector as such are not scalars, since they change with a change of coordinate system; a scalar field may however for one choice of the coordinate system be equal to a particular component.
