A physical quantity is something that can be measured. Scalar quantities only have size (or magnitude). Vector quantities have size and direction. Speed is a scalar quantity - direction is not ...

Notice how the quantities above have both a size and a direction associated with them. The direction of a vector can be given in a written description, or drawn as an arrow. The length of an arrow ...

Students learn to distinguish between scalar and vector quantities. Introduction to Vectors: Students learn to distinguish between scalar and vector quantities and how to state the magnitude and ...

From a metaphysical point of view, it is important clearly to see the ontological difference between what is studied in mathematics and mathematical physics, respectively. In this respect, the paper ...
