What is most often given a value of zero to describe an object’s position on a straight line? displacement reference point distance ending location

Reference point.

Explanation: Usually, when we are describing the motion of an object, the position of the object at time zero (also called the initial position ) is where we need to put the zero in our position axis. This point is called the "reference point", this means that if the position at a time T is X, we know that the difference between the actual position and the initial position (in this case X - 0) is equal to the total displacement of the object. This is why it is called a reference point.
