To clarify the concepts of distance and displacement in the context of Kelly's pool game:
Distance refers to the total path traveled by the ball, regardless of direction, while displacement refers to the straight line from the initial position to the final position, taking direction into account.
In this case:
- Distance traveled by the 9 ball: 7 meters (the total distance the ball moved).
- Displacement of the 9 ball: 1 meter to the left (the straight-line distance and direction from its starting point).
Given this understanding, a correct statement regarding distance and displacement could be:
"The distance traveled by the 9 ball was 7 meters, while its displacement was 1 meter to the left of its initial position."
This statement accurately reflects the difference between distance and displacement in the scenario described.
