Answer:
Velocity is the speed of something in a given direction, and (in general use) speed.
Explanation:
In science and physics the standard unit of measure for speed is generally meters per second or m/s. The measurement of speed can reflect two different scalar quantities. Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of a body and its direction of motion.
