Velocity equals distance traveled divided by time of travel the speed plus the direction of travel. A device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity can thereby move due to the conservation of momentum. Velocity v is a vector quantity that measures displacement or change in position Ds over the change in time Dt represented by the equation v DsDt.

Is the final velocity. Velocity is a measure of how quickly an object moves.
