Example 2

medium
A runner completes one full lap around a 400 m400 \text{ m} circular track. What is the runner's displacement and total distance?

Solution

  1. 1
    The runner returns to the starting point after one full lap.
  2. 2
    Distance traveled: 400 m400 \text{ m} (total path length).
  3. 3
    Displacement: 0 m0 \text{ m} (start and end positions are the same).

Answer

Distance=400 m,Displacement=0 m\text{Distance} = 400 \text{ m}, \quad \text{Displacement} = 0 \text{ m}
Displacement depends only on the initial and final positions, not on the path taken. For a closed loop, the displacement is always zero regardless of the distance traveled.

About Displacement

The change in position of an object, measured as the straight-line distance and direction from the starting point to the ending point.
