This resource explores the concepts of position, distance, and displacement in a one-dimensional context, using the scenario of hikers on a trail as a relatable backdrop. It begins by introducing the idea of an origin as the reference point necessary for defining location. Position is characterized as a vector quantity that specifies both distance and direction relative to the origin. The document differentiates between distance, as a scalar quantity representing the total path traveled, and displacement, a vector quantity indicating the straight-line change in position. Various examples illustrate how to calculate each of these metrics, underlining the importance of direction in displacement values. Moreover, the document provides a clear distinction between scalar and vector properties, culminating in a final task that encourages application of the concepts learned.
