Question

Consider the motion of an object moving along a straight path. The object starts its journey

from O which is treated as its reference point.

Let A, B and C represent the position of the object that moves through C and B reaches A.

Then it moves back along the same path and reaches C through B.

The total path length covered by the object is OA+ AC. This is the distance covered by the

object.
