VECTORS

Vectors are measurements that have both magnitude and direction. Vector quantities are used frequently in both math and physics; vector usage has both basic and complex applications. Vectors are represented by straight lines with a head on one end (denoted by an arrow,) and a tail (denoted by a “flat” end) on the other. As might have been assumed, the arrow represents the direction of the vector, and the length of the line represents the distance of the vector.

[The meaning of the word "vector" itself has a definition that lends itself to desciribing many other phyics related terms (each that complys with having both a direction and a magnitude) such as velocity as opposed to speed, which connotes only magnitude and not direction.]
