To me this is
crystal clear !
Of course,
the draft needs to be "cleaned up" just a bit .... a couple of minor typo's
addressed, and the references added.
Important, I
think, is the fact that the STOP is addressed in terms of ceasing to accelerate
as well as providing a firm base holding the rod as it straightens. Also,
the concept that the less time taken to cease acceleration, the faster the
unloading. This despite the fact that once we have ceased to accelerate
altogether, the timing of rod unloading from that point is a
constant.
The idea that
we have continued acceleration even as we reduce acceleration until we reach
zero acceleration will, I think, create a spark of understanding to those who
might not otherwise understand. This fits with the average instructor's
concept of a "quick stop". What he is really doing, in other words, is
quickly going from a given acceleration to zero and calling it a
"stop".
I noticed
that the terms "deceleration" and "negative acceleration" were not used in
describing this.
Interesting
that the timing of the "unloading" process has no impact on the total energy
released.
So why stop
? Especially when we see that elite casters do this and achieve greater
distances ???? (This will be the crux of uninformed
disagreement)
The answers
are multiple and appear in text as:
1.)
Acceleration is reduced to zero in less time.
2.) A firm
base is supplied against which the rod can unflex.
3.) It
helps provide control the rod tip path.
4.)
Trajectory is more efficiently controlled.
It still
boils down to the fact that 1.) - 4.) can be accomplished by the student being
instructed to STOP. This student doesn't need to know that this isn't what
he's really doing or the fact that his most important accomplishment is the
reduction of acceleration to zero as rapidly as he can along with the
provision of a firm base for rod unload. In fact, teaching the average
student the physics behind the whole thing might well lead to
frustration.
YET THE
MASTER INSTRUCTOR SHOULD LEARN THIS TO HAVE AN IN DEPTH UNDERSTANDING AS
BACKGROUND FOR HIS/HER TEACHING .
I'll provide
one of the references:
