Lab on the Relationships of Time, Distance, and Acceleration at Constant Velocity Initial velocity is the speed and direction in which the object is moving at the beginning of a time interval and final velocity is the speed and direction the object is moving at the end of a time period. Average velocity is the average speed and direction of the object. An example of this is a car starting at rest, facing west has a velocity of 0m/s and after 10s it has reached a speed of 20m/s in a westward direction.
