Part of the IT standards and organizations glossary: Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed) is the meter per second (m/s).Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.art of the IT standards and organizations glossary: Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time.
