Expert Answer:
When initial and final position of the object during motion is same its displacement is zero.
Distance and displacement are two different quantities.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Displacement is a vector quantity that refers to the object's overall change in position.
A person walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North.
Even though the person has walked a total distance of 12 meters, his displacement is 0 meters. It is because the initial position and final position are same.
