Question

What's the most often given a value of zero to describe an object position on a straight line

Answer 1

B. The reference point is the 0 of a straight line description. Left of it would be negative and right of it would be positive.

Answer 2

Answer:

Reference point

Explanation:

To explain the position of an object, we have to choose some location or point from where we start to observe the position of the object. This point is called reference point.

As we move leftwards from the reference point, the position of the object is taken as negative and if we move rightwards from the reference point, the position of the object is taken as positive.
