In addition to finding a vector’s components, it is also useful in solving problems to find a vector in the same direction as the given vector, but of magnitude 1. We call a vector with a magnitude of 1 a unit vector. We can then preserve the direction of the original vector while ...

This chapter describes, from the perspective of mathematics education research, approaches to the concept of the vector and the problems that students typically experience in dealing with vectors. It also discusses, from the perspective of physics education research, the role of arrows (as vectors) ...

Let’s examine vector algebra using a graphical method to be aware of basic terms and to develop a qualitative understanding. In practice, however, when it comes to solving physics problems, we use analytical methods, which we’ll see in the next section. Analytical methods are more simple co...
