Answer:
Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). ... If there is a change in speed, direction or both, then the object has a changing velocity and is said to be undergoing an acceleration.
Other units: mph/fts
In SI base units: m/s
