The difference between distance and displacement can be illustrated with numerical examples. Which of the following statements is correct?

• Distance and displacement are always equal, regardless of the path taken.

• Displacement is always greater than distance for any path taken.

• Distance is the shortest path between two points, while displacement is the total path covered.
