उत्तर
The minimum distance between the start and finish points of the motion of an object is called the displacement of the object.
Explanation:
Displacement means the shortest distance between the start and end points of the motion. Displacement is a scientific term related to speed and distance. This displacement represents how the body moves from one position to another, that is, the shortest distance between its motion’s start and end points.
