This tutorial is about basic vector math that is needed to be able to do a lot of the physics code. I leave out some details that will be explored in greater depth when we come to a particular section that requires it (such as vector projection, and vector/matrix math). I go over how to do vector addition, dot product, component product, cross product, the normalization of vector, finding the length of vectors, and how the dot product relates to the angle between vectors.
