Displacement
Displacement is also known as distance. Unless otherwise specified, displacement is defined along a straight line. We might say that Minneapolis, Minnesota, is 100 km from Rochester, Minnesota, “as the crow flies,” or along a straight line. If you were to drive along U.S. Route 52, however, the displacement would turn out to be closer to 120 km because this highway does not follow a straight path from Rochester to Minneapolis.
