Question

In a car race on a circular track, where the start and finish line are the same, what quantity is neglible?

Answer 1

total displacement

To return to the first image, these cars travel a distance of 500 miles over the course of the race. However, they are traveling in a circle, and the start and finish line are the same. Therefore, when the car finishes the race, it is in essentially the same position it was when it started. The car's total displacement is only a few feet.
