Vector
geometric object that has magnitude (or length) and direction / From Wikipedia, the free encyclopedia
This article is about a mathematical concept. For other uses, see Vector (biology).
A vector is a mathematical object that has a size, called the magnitude, and a direction. It is often represented by boldface letters (such as ,
,
), or as a line segment from one point to another (as in
).[1][2]

For example, a vector would be used to show the distance and direction something moved in. When asking for directions, if one says "Walk one kilometer towards the North", that would be a vector, but if they say "Walk one kilometer", without showing a direction, then that would be a scalar.
We usually draw vectors as arrows. The length of the arrow is proportional to the vector's magnitude. The direction in which the arrow points to is the vector's direction.[3]
