Acceleration is a vector because it has a magnitude and a direction (Accelerating at a rate of 5 Miles Per Hour North). Speed is a scalar because it only has a magnitude (35 Miles Per Hour) . Velocity is the derivative of the acceleration and is also a vector (35 miles per hour North). Adam Â· 5 years ago. Thumbs up.
Best Answer: acceleration is expressed as a unit of distance per unit of time per unit of time. standard units are meters and seconds. For example gravity produces an acceleration of 9.8m/s/s which says the speed increases 9.8m/s every second. m/s divided by s is same as m/s^2. So standard acceleration units (that you will get working with kg and N) is m/s^2
