Which term refers to the length of an object's change in position, without considering direction?

The term that refers to the length of an object's change in position, without considering direction, is distance. Distance is a scalar quantity, meaning it only has magnitude and does not include any directional information. When measuring how far an object has moved, distance tells us the total path length traveled, regardless of the path taken.

In contrast, displacement considers both the distance and the direction of the change in position, making it a vector quantity. Magnitude refers to the size or quantity of something and does not specifically refer to the measurement of an object's movement. A vector is a quantity that has both magnitude and direction, but the question specifically asks for a term regarding the change in position without direction, solidifying distance as the correct choice.
