Position refers to the location of an object relative to a reference point, the path length is the total distance traveled along a path, and displacement is the straight-line distance between the initial and final positions, regardless of the actual path taken.
Δx = xf − x0, where Δ x is displacement, x f is the final position, and x 0 is the initial position. We use the uppercase Greek letter delta (Δ) to mean “change in” whatever quantity follows it; thus, Δ x means change in position (final position less initial position).
A position is a vector because it has both a magnitude and a direction: it is some distance from a zero point (the point we call the origin) in a particular direction. With one-dimensional motion, we can define a straight line along which the object moves. Let’s call this the x-axis, and
Initial position refers to the starting point of an object in motion before any forces act upon it. This concept is crucial when analyzing free fall, as it helps to establish where the object begins its journey and allows for the calculation of various kinematic equations that describe its motion under the influence of gravity.

Measurement from your initial position to your final position is distance traveled, and the measurement of the total length of your path from the starting position to the final position is displacement.

What is a change in position called?
Definition. The initial position refers to the starting location or point in space of an object or system before any motion or change in position occurs. It is a fundamental concept in the study of kinematics, which is the branch of physics that describes the motion of objects without considering the forces that cause the motion.
