AC HPAT Physics Exam Solved 100% Correct!! DIstance · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direc...
