What is the SI unit of velocity?
AKilometres per hour
BCentimetres per second
CMetres per second squared
DMetres per second
Answer & Solution
Correct answer: D. Metres per second
1. Velocity is a displacement divided by a time.
2. The SI unit for velocity is metres per second, written m/s.
3. Kilometres per hour and centimetres per second are in common use but are not the SI unit.
4. Metres per second squared is the unit of acceleration, not velocity.
