    Walter & Group....

     

    Hi Gordy;
     
    It seems that this huge amount of discussion regarding acceleration has been confined to all types of casts. Hmmm, I say that acceleration issue must address the various types of casts. Retrieving line with a roll cast involves a different amount and kind of acceleration, for example.
     
    Perhaps in this discussion we should examine the various casts. In all of Mel Krieger's instructional videos he vocalizes "whuuuuump"; accelerating to a stop. His method was almost biblical for a beginning casting student - "whuuuuMP! Yet different cast, while the basics were the same, would challenge one to think that the issue of acceleration is germaine to the type of cast that one is making.
     
    Your comments.

    Robert....

    My thought is that the acceleration principles all apply no matter the kind of cast .... but the timing will change as will the path of the rod tip.   Interesting to have some other opinions on this.

    From Steve Hollensed...

    Hi Gordy,

    In my comments about acceleration, I left out one word that makes a

    world of difference.

    I agree with Walter that the rate of change of a rate of change, is in

    fact, perfectly ok. But the rate change of the SAME rate change (as in

    the rate of velocity change of the rate of velocity change) doesn't make

    sense and I think that is what the term "accelerated acceleration"

    implies.

    And I certainly agree with Mac that limiting ourselves as instructors

    will hold back many students from reaching their full potential. This

    study group certainly expands and stretches my thinking. Thanks for

    providing this great forum and all of the brain food that goes along

    with it.

    Steve ....    OK ... but what happens with the launch of a space shuttle.  Obviously, there is acceleration as it ascends from the launch pad.  Does it move with constant acceleration ? .... or does this acceleration change as it goes farther into space ?  In the event that it does. what term would we use to describe this ?  .... 3rd order mathematical progression ????????
