## How are vectors used? |

Many physical quantities—especially those in association with mathematics and science—can be represented by vectors, such as force, velocity, and momentum. In specifying these quantities, one must state not only how large it is but also in what direction it acts. Even more complex is the use of multidimensional vectors for such problems as relativity, wind velocities in an atmosphere, and in determining electromagnetic fields.
