Which term refers to the length of the path taken when a body moves from one point to another?

The term that refers to the length of the path taken when a body moves from one point to another is distance. Distance is a scalar quantity, which means it only has magnitude and does not consider the direction of the movement. It represents the total length of the actual travel route between two points, regardless of whether that route is straight, curved, or takes a circuitous path.

In contrast, displacement is a vector quantity that measures the shortest straight-line distance from the initial position to the final position, along with the direction of that line. It does not account for the actual path taken during the movement.

The term "pathway" might imply the specific route or method followed during the movement, but it does not quantify the length in the same way that distance does. Similarly, "travel" generally refers to the act of moving from one place to another rather than measuring the length of the path. Therefore, distance is the most accurate term to describe the length of the path taken during movement.
