Displacement Math Example 1
Follow the full solution, then compare it with the other examples linked below.
Example 1
easyA person walks 5 m east and then 5 m west. What is their displacement?
Solution
- 1 Step 1: Represent east as positive x and west as negative x.
- 2 Step 2: Displacement m.
- 3 Step 3: The person is back at their starting point โ zero displacement.
Answer
Displacement = 0 m (back to start).
Displacement is the straight-line vector from the starting point to the ending point. It depends only on start and end positions, not the path taken. Total distance walked was 10 m, but displacement was 0 โ an important distinction.
About Displacement
The straight-line change in position from start to end, with both a distance and a direction.
