Recall that a “point” has a location but no real size or thickness. In this chapter, we have learned how a “vector” has magnitude and direction, but no position. So “points” and “vectors” have different purposes, conceptually: a “point” specifies a position, and a “vector” specifies a displacement.

This finally makes sense to me! A vector can displace an object by the value of the vector and move it to a point with a position.
