Want this question answered?
we need a fixed reference point to describe the position of a body
To completely describe the motion of an object you will need to know (1) the object's position in space and time, (2) the objects velocity, including the direction of travel, and (3) the object's acceleration, including the direction of acceleration. However, the Heisenburg Uncertainty principle states that the more accurately you measure object's position, the less information you will have about its velocity, and vica versa. The more accurately you measure an object's velocity, the less information you will have about its position.

When it changes position or something to do with the speed.
a reference point i just had that test a while ago!

It is important to discuss two locations to describe the position of an object. The two locations helps us to best discuss the object.
