Answer:
Explanation:
These magnitudes depend on some origin point as reference because they are vector magnitudes. This means that they depend on direction, magnitude and sense. For example instantaneous velocity depend from where you are measuring, and position of some object also could change depending of the point of reference.
If you are in the top of some building, you can say that you are at 8 m from the street (reference). But also, you can say that you are at 0 m from the roof (changing reference point).
