which is a valid velocity reading for an object? 45 m/s 45 m/s north 0 m/s south 0 m/s
Answer
Brief Explanations:
Velocity is a vector quantity, which means it has both magnitude and direction. Options with just a magnitude like 45 m/s and 0 m/s are speed values (scalar). Options with magnitude and direction like 45 m/s north and 0 m/s south are valid velocity readings.
Answer:
B. 45 m/s north, C. 0 m/s south, D. 0 m/s
