Since you want to be definitional correct; why not go to what is speed/velocity and what is pace?
Since the brilliant minds like Aristotle, Galileo, Newton, Einstein, and others got involved many years ago speed/velocity has been defined as motion and pace as the rate of motion.
Also speed/velocity and pace are interdependent and it doesn’t make any difference if the causation of their motion is by man, animal, or machine.
Therefore we can look at a simple horseracing example depicting this interdependency.
A race has the following characteristics:
Final time = 1 minute, 9 seconds
Race distance = 3960 feet or three-quarters of a mile
Race timed by quarter-mile and final time
Winning Horse and tack weigh 1204 Lbs.
Questions:
What is the time of the race?
Ans. = 69 seconds
What is the speed of the race?
Ans. = Speed is Distance/Time = 57.39 Ft per second
What is the pace of the race?
Ans. = Pace by 1/4m = 23 sec
Going a step further and calculate surface resistivity (Coefficient of Kinetic Friction) or track surface variant we can see the following (calculated in metrics):
Deceleration = Rate of Travel/ Time of travel = 17.50/69 = .253623
Force to decelerate @ .253623m/ sec = 546*.253623 = 239.93 N
Maximum Stopping Force = 546*9.8 = 5350.8 N
Coefficient of Kinetic Friction = .04484 = Force to Decelerate/Maximum Stopping Force
