Scalar and vector quantities are ubiquitous in physics. However, most physics texts at the undergraduate level provide only a brief description of their nature. This creates confusion for many: all magnitudes are scalars and any physical quantity with magnitude and direction is defined as vector. ...

In introductory textbooks in physics, a vector is normally defined as something which possesses both magnitude and direction in space. It is also normally printed in heavy type, for example the velocity u of a body is written as * $$u = {iu^x + }{ju^y + }{ku^z}$$ where i, j...

length used only to specify a given direction. Unit vectors have no other physical significance. In Physics 2110 and 2120 we will use the symbols i, j, and k (if there is a third dimension, i.e a “z” direction), although in many texts the symbols x^, y^, and z ^ are often ...
In this work, we present preliminary results of ongoing research in the development of an augmented reality system to facilitate learning of Euclidean vectors properties in physics. The system aids the user to understand physical concepts, such as magnitude and direction, along with operations like ...
but there are in physical science many other important ideas which call for a more direct notation. To avoid any narrow hypothesis I denominated my first paper “Principles of the Algebra of Physics”; but in the notice which NATURE honoured it with it was printed as “Principles of the Alge...

Understanding the nature and application of vectors and tensors is critically important to students of physics and engineering. Adopting the same approach used in his highly popular A Student's Guide to Maxwell's Equations, Fleisch explains vectors and tensors in plain language. Written for ...
