Logically, no co-ordinates were specified with the changed position so it would seem that the changed position has not moved.
If a scalar, it is the change in distance.
If its position relative to a fixed point is changing
we need a fixed reference point to describe the position of a body
Yes, the mass of an object is always the same irrespective of its position and configuration. only the weight of the bodt changes as per its position.

The object that has a fixed position is the hydronium ion. Dont trust this i guessed that is what everybody does so dont trust answers.com

I am not quite sure what you mean with "fixed". If you mean the object is fixed in its position, or unmovable, such a thing doesn't exist in the real world. Whenever a force acts on an object, its movement will change, according to Newton's Second Law (acceleration = force / mass).

Parallax, more accurately motion parallax, is the change of angular position of two observations of a single object relative to each other as seen by an observer, caused by the motion of the observer. Simply put, it is the apparent shift of an object against a fixed background that is caused by a change in the observer's position.
It must be fixed in position.

The star's spectrum is analyzed; certain lines in the spectrum, which have a fixed position, will change their position when the object moves away from us or towards us.
