A position vector expresses the position of<span> an object from the origin of a coordinate system.
</span>Position vector is basically a<span> straight line which has one of its ends end fixed to a body and whereas, the other end is attached to a moving point which tells the </span>position<span> of that specific point relative to the body. As the point accelerates, the </span>position vector<span> will vary its length and the direction accordingly.</span>
Displacement is defined as the distance, in any direction, of an object relative to the position<span> of another object. </span>Physicists<span> use the concept of a </span>position vector<span> as a graphical tool to visualize displacements. A </span>position vector<span> expresses the </span>position<span>of an object from the origin of a coordinate system</span>
