Velocity is a measure of both the speed and direction that an object is traveling. Technically it is the time rate of change of displacement. Average velocity is calculated by dividing displacement by time. Velocity is measured in meters/second (SI units) or feet/second (English units).
Do not forget that when using velocity, the direction of motion is as important as the speed of the object. Three different skating scenarios are provided below to illustrate the concept of velocity.
