One of the most important topics taught at the start of introductory physics is the idea of vectors. Students really need proficiency with them if they are to use force and momentum. Just about every ...

If \(\overrightarrow {PQ} = \left( {\begin{array}{*{20}{c}} a\\ b\\ c \end{array}} \right)\) then the magnitude of \(\overrightarrow {PQ}\) is written as \(\left ...

pre-reqs: trig Think of the following two things. Temperature and wind speed. These are two different things that you could measure, but there is one big difference. Wind speed has two parts to it - ...

A vector can be represented by a line segment labelled with an arrow. A vector between two points A and B is described as: \(\overrightarrow{AB}\), \(\mathbf{a}\) or \(\underline{a}\). The vector can ...
