− | + | A { free vector } does not change its properties (magnitude and direction), if it is shifted parallel to itself so that its startpoint is translated to an arbitrary point in space. If the properties of a vector are constrained to a certain point, then it is a { constrained vector }. A vector pointing from a fixed origin to a certain point in space is called { position vector }. | |
