Displacement (s or d) is the shortest straight-line distance from the initial position to the final position of an object, with a direction. Distance (d) is the total length of the path traversed by an object, regardless of direction.

Displacement is the shortest straight-line distance from the initial position to the final position of an object, and it includes a direction. It is a vector quantity.

Distance is the total length of the path traversed by an object, regardless of direction. It is a scalar quantity.

The main difference is that displacement considers only the start and end points and includes direction, while distance considers the entire path taken and does not include direction.
