When you walk 2 miles east and then turn around and walk 2 miles west, the values for distance and displacement are as follows:
-
Distance: This is a scalar quantity that measures the total length of the path traveled. In this case, you walked 2 miles east plus 2 miles west, so the total distance you traveled is \(2 + 2 = 4 \) miles.
-
Displacement: This is a vector quantity that measures the change in position from the starting point to the final position. Since you started at a point, walked 2 miles east, and then walked back 2 miles west, your final position is the same as your starting position. Therefore, your displacement is \(0\) miles.
In summary:
- Distance = 4 miles
- Displacement = 0 miles
