# 41+ Position Vector

**41+ Position Vector**. As the point moves the vector's position will change in length or in direction or at times in both direction and length. 8/23/2005 the position vector.doc 3/7 jim stiles the univ.

In geometry, a position or position vector, also known as location vector or radius vector, is a euclidean vector that represents the position of a point p in space in relation to an arbitrary reference origin o.usually denoted x, r, or s, it corresponds to the straight line segment from o to p.in other words, it is the displacement or translation that maps the origin to p: The position vector of a particle is defined as the vector starting from the origin to the point where the particle is. You need to understand what a position vector is to be able to answer the questions involving vector geometry.

### If you find yourself puzzling about the position vector, read this section.

The position vector r extends from the origin to the particle, while the velocity vector v points in the direction of the particle's motion. If you find yourself puzzling about the position vector, read this section. So in the above line you are doing something like, pins1.position = vector3.new (vector3.new (x, y, z)) which does not make any sense. As the point moves the vector's position will change in length or in direction or at times in both direction and length.
