Give an example of a trip you might take in your car for which the distance traveled as measured on your car’s odometer is not equal to the displacement between your initial and final positions.
Solution 6CQ Ok, to do this problem we will imagine the motion of a person along a circular path. Consider the diagram, A person starts at point “A”, travelled in the clockwise direction. Eventually after passing point “B & C”, he finally reaches point “A” again from where he had started. By completing one rotation he has covered a distance of the circumference of the circular path which is 2R, a nonzero number. But what about the displacement The end points are same, so the displacement is zero. Which means that, after moving along the distance 2R, he has not displaced at all. That’s absurd but true. This is the fundamental difference between distance and displacement.
