   I was rethinking this topic and had to confront this concept   
   of second order acceleration.  The "jerk" effect is this   
   kinetic.   
      
   The modern athlete needs resolving given jerk theory.  The   
   body movements in modern basketball are likely the most dominate   
   example of jerk.  So I would propose to formalize this kinetic   
   and give the name to it.  Having "game" is to be formalized.   
      
   Maybe this is obvious, might be my problem, but I needed to   
   philosophically express it.   
      
   Observing the horse accelerate might not show game.  But   
   humans can be taught to express a certain behavior right off   
   a sprinter's starting blocks.  What function of acceleration   
   might match the runner's legs given an efficiency variable?   
   The runners gait is exploding from zero to full length.   
      
   There is a choice.  What is the initial state?  What is the   
   first step gait wise?  Start small? Start larger? Start like   
   the winners?  Here the answer is to follow the winners, but   
   what if the scenario was uncommon?   
      
   Having game here would be like starting to run standing up.   
   And having the winner move to a crouch to alter the second   
   acceleration.   
      
   This concept can be used in general to look for kinetic   
   opportunity.  Examining aircraft control and performance   
   in scenario would be one example.   
      
   The most heartbreaking failure in my life was the final   
   discovery of microbursts' effect on landing aircraft.   
   The second kinetic was not used to analyze the crashes.   
   It took correlation of rain shafts to determine air   
   downshaft  existence.
