Answer:
Displacement and distance;Distance traveled is needed to calculate average speed (i.e., total distance over a period of time).Displacement is needed to find the final position of an object; it tells not only the distance from the starting position, but also the net direction of travel.
Speed and acceleration;Basically, an object's speed tells you how fast it's going. Its velocity tells you how fast it's going in a certain direction. You use speed measurements in your daily life, but physicists depend on velocity measurements more frequently in their work.
