I think it is acceleration
Let me know if it was right!
Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1). Velocity shows: magnitude, direction and speed!
Hope this helps. Have a great day.
