    Definition: Force vs Power
    From: Dave Weilacher
    Date: 2003 Apr 24, 05:46 -0400

    Recently, we were discussing effect of wind and current.  Actually, I believe we still are.
    It was suggested that Force = mass X velocity.  Also, that Power = velocity 
    squared.  (or is it mass X velocity X velocity?)
    First, is this stated properly by me.
    Second,  can these notions be expressed in a way that my uneducated brain can grasp?
    Well, an unfair question. How could you possibly know what my brain will 
    grasp?  It is even a mystery to me.
    A clue might be that I had no trouble visuallizing George H. dragging his 4 ft 
    board through the water behind his submarine.  Perhaps this example could be 
    expanded  to relate the difference between force and power.
