Hi....
In the interest of comparative phylology, and for better understanding between many of us and our physicist and engineering fly casters, I thought it might be a good idea to come up with a brief lexicon of terms we use in describing casting mechanics both from a common usage and an engineering standpoint.
Starting with 4 of what appear to be terms that are used in a different way by each, I'll list simple common "definitions" from Websters Dictionary, and then ask that those of you who are engineers or physicists to come up with definitions which will be more scientific.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I.) SPEED : RAPIDITY IN MOVING, GOING, TRAVELLING, PROCEEDING OR PERFORMING.
SYNONYM: (# 13....WEBSTER) : ACCELERATE.
(Server has correctly pointed out that in the lexicon of engineers, accelerate or acceleration is NOT a synonym for speed or velocity.)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
II.) VELOCITY : 1...RAPIDITY OF MOTION OR OPERATION; SWIFTNESS; SPEED
2...(MECH.) : THE TIME RATE OF CHANGE OF POSITION OF A BODY IN A SPECIFIC DIRECTION.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
III.) ACCELERATE : 3...(MECH.) TO CHANGE THE VELOCITY OF (A BODY) OR THE RATE OF (MOTION).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
IV.) ACCELERATION: 3...(MECH) THE TIME RATE OF CHANGE OF VELOCITY WITH RESPECT TO MAGNITUDE OR DIRECTION; THE DERIVATIVE OF VELOCITY WITH RESPECT TO TIME.

Peter Minnick has just sent me a book entitled, THE PROFESSOR AND THE MADMAN by Simon Winchester. I'm studying it for the second time. It's a fascinating treatise on the development of the OED (Oxford English Dictionary). It took over 40 years and the input of literally thousands of contributors among which were several genius phylologists, lexicographers and authors to complete this work and is faintly reminiscent of the 2+ years of work that our FFF Glossary Committee has put into our deliberations on only a few flycasting definitions.
