Distance vs Displacement As an object moves, its location undergoes change. There are two quantities that are used to describe the changing location. One quantity - distance accumulates the amount of total change of location over the course of a motion. Distance is the amount of ground that is covered. The second quantity - displacement - only concerns itself with the initial and final position of the object. Displacement is the overall change in position of the object from start to finish and does not concern itself with the accumulation of distance traveled during the path from start to finish. True or False: An object can be moving for 10 seconds and still have zero displacement. A. True B. False
