A physical quantity can be either a scalar or a vector; thus, a field can also be a scalar field or a vector field. A scalar field is specified by a single number at each point. Some well-known ...
The direction of a vector can be given in a written description, or drawn as an arrow. The length of an arrow represents the magnitude of the quantity. Displacement is the overall distance from a ...
