such that scalars can be added, subtracted, or multiplied, in the same way, as numbers. However, the operation of the scalar quantities with the same measurement unit can be possible. The multiplication of two scalar quantities is known as thedot product. ...

Describe what is meant by scalar and vector quantities, giving examples, Distance as an example of a scalar quantity and displacement as an example of a vector quantity, Describe how a vector quantity can be represented by an arrow, examples and step b
Is density scalar or vector? Density is ascalar quantity, having only magnitude and giving no information about direction. We can also reason that, because density is equal to mass divided by volume and both mass and volume are scalar quantities, density must also be a scalar quantity. ...
In physics, a differential is an infinitesimal change in or amount of some quantity. For example, d p is a small change in linear momentum, and d m is a small amount of mass. Ratios of differentials become derivatives, while Riemann sums of differentials become integrals. Given some vector...

Thus the dichotomous arrangement of quantities as scalar or vector been supplemented by the tensor-triplet as a tertium quid, vectors are habitually grouped as free or localised, pseudo-scalars have been set off from pure scalars. Something has been done, too, through influence of ascertained ...
Michael Dickson, in Philosophy of Physics, 2007 7.1.1 Vector Spaces A vector space, V, is a set that is closed under addition and ‘multiplication by a scalar’ from a field, K. These operations must satisfy, for any u, v, w∈ V and k, k′∈ K: (commutativity) v + w = w +...
