Dealing with Vectors Vector Components Any vector can be expressed as a sum of a number of other vectors. The vectors which are summed are called the components of the original vector. When you want ...

Vectors have units, if you leave them off you are probably a mathematician (just kidding). Also, this notation can be expanded to three dimensions by adding a z-hat or k-hat component.

Vector components Any vector can be resolved into two components at right angles to each other. These two components when added together have the same effect as the initial single vector.
