Position Vector of a Point - Definition, Example, Class 11 (3D-Geometry). In this lecture you will learn definition and example of position vector. What is position vector and why is it so important in vector algebra with example. The position vector of a point in space is a vector from origin of the coordinate system to the point. Thus, to each point P in space there corresponds a unique vector. Such vectors are not movable and they are often referred to as bound vectors. The addition of two position vectors are not possible. But in contrast subtracting them gives a sensible meaning. I have explained whole concept through an example.
