Select and explain Select the correct statement and explain the difference between the two quantities in this journey.
Predict from the governing principle before looking for a matching option. Then reject alternatives by checking direction, units, limiting behaviour or the physical meaning of each statement.
- 1
Selects option B: distance = 400 m and displacement = 0 m.
- 2
Explains that distance is the total path length, so it is 400 m.
- 3
Explains that displacement depends only on the change in position, which is zero because the runner returns to the start.
