about motion of an object

Expert Answer:

The reference point is t = 0. Since we plot time on x axis, all we meant by 'starts it's motion from negative side' is whatever past motion i.e. before t = 0, the object had, all of it on negative side of x, the time axis, and it comes/starts from that side.
