displacement trajectory

Displacement trajectory refers to the straight-line path from an object's starting point to its ending position, regardless of the actual route taken. It focuses on where the object ends up relative to where it began, emphasizing the shortest possible distance and direction between these two points. Unlike the actual route traveled, which might be winding or indirect, the displacement trajectory is a direct, “as-the-crow-flies” line that represents the overall change in position. It helps in understanding movement in terms of overall change in location, without considering the specific path taken.
