A cable car is tested on a straight sloping track. A technician chooses up the slope as the positive direction.
| Record | Recorded quantity |
|---|---|
| A | mass |
| B | velocity of 8.0 m/s up the slope |
| C | velocity of 8.0 m/s down the slope |
| D | energy transferred |
Explain how each record should be classified as a scalar quantity or a vector quantity. Your answer should include which velocity would be written with a negative sign and why records B and C are different velocities.
