In mathematics, a vector space is a collection of vectors that is closed under addition and scalar multiplication.
Vector addition is the process of combining two or more vectors to produce a resultant vector.
A unit vector is a vector with a magnitude of 1 and is often used to indicate direction.
Velocity is an example of a vector quantity because it has both magnitude and direction.
In physics, a vector field is a function that assigns a vector to every point in space.
