Displacement:
Displacement is also termed as distance. Unless or else identified, displacement is defined along a straight line. We may say that Minneapolis, Minnesota, is 100 km from Rochester, Minnesota, "since the crow flies," or all along a straight line. When you were to drive along U.S. Route 52, though, the displacement would turn out to be nearer to 120 km as this highway does not follow a straight path from Rochester to Minneapolis.
