A robot starts at x = −2 m, moves to x = +5 m, then ends at x = +1 m. Find each displacement, the total displacement, and the distance.
| Criterion | Points |
|---|---|
x1 Calculates the first displacement as +5 − (−2) = +7 m. | 1 |
x2 Calculates the return displacement as +1 − (+5) = −4 m. | 1 |
x3 Calculates total displacement as +3 m using signed addition or final minus initial position. | 1 |
x4 Calculates distance as |7| + |−4| = 11 m rather than the signed displacement sum. | 1 |
