Question

A body starts from a point A and moves to the point B. If it returns to the same point, find the displacement, distance, velocity, average speed.

Answer 1

If it starts from the pointA and again return to pointA so its displacement will be zero(because displacement is the shortest distance) and its velocity will be aslo zero because velocity=displacement/time.
Distance will be total distance means distance from A to B and then again B to A. average speed will be total distance/total time.
