The table gives two records from a motion sensor.
| Record | Speed | Direction |
|---|---|---|
| P | 4.0 m s−14.0\ \mathrm{m\,s^{-1}}4.0 ms−1 | North |
| Q | 4.0 m s−14.0\ \mathrm{m\,s^{-1}}4.0 ms−1 | South |
Which statement correctly compares the records?
The scalar speed is the same; the vector velocity is different.
The vector speed is the same; the scalar velocity is different.
The scalar speed is different; the vector velocity is the same.
The vector speed is different; the scalar velocity is the same.
