I understand that Jim, as you see below quote from my last post. The energy supplied is unknown
Yes the amount is unknown..
I think unlikely to be delivered in a single burst or bang.
Well this is the whole idea of fajing and short power, you are trying to release or transfer all the energy to the connected mass in the shortest time.
Do you train short power? Like hitting your partner with your fist or hand only a few inches away? Ever see Bruce in that old interview demo the punch.? Note the travel in the punch, the travel or distance of the punch was very short and not the point, it was the velocity and connectedness in the short travel distance of the strike.
Let me repeat: The velocity and connectedness <before and during impact> is what this is all about!
This relates to short power, you only have that short space to make the transfer, unlike with say a reverse punch that has a long length of expansion and therefore time to transfer energy.
I think it will still be accelerating when it meets the target
Well it will not be accelerating AFTER it meets the target, but it could be accelerating up until it meets the target.. But the cycle should be near complete at this point and at least the way we teach the WCK striking the muscles need to shut off meaning that pushing the strike after impact is not correct or desirable.
I know we disagree on this point as I`m not convinced that all enegy can be drained from the body in releasing a strike as then it would be at it`s end point
The idea here is that energy transferred after contact is not useful since by definition it cannot be transferred to the accelerating mass for impact since impact has already happened. The idea of a strike vs. a push.. or a strike and then a push.
and must recoil (better than lock at end point). On contact yes, it seems more likely as there is nothing to left to accelerate...it essentially places all the energy into the person struck and he/she has to deal with it.
In the air the strikes <punching air or missing> we train the muscles to shut off before full extension of the arm or elbow joint. The bicep is not used at all and the ligaments stop the punch at the end of travel.
I`m thinking my arm is the train and the faster the train goes should create more damage after impact, but the "train" is linked to the body which is the engine of the train and if that engine is moving forward as well as fueling the train for constant acceleration
This is all true but I do not see what your point is..
The idea is that any energy left after the connected mass strike makes the impact is not going to increase the impact force, nor will a "push" at the end of the strike do much in the way of increasing damage since it is very much a last minute push.
So yes full extension and power transfer may not be complete on impact but the energy push trailer isn't what's doing the damage as there is no accelerating connected mass to transfer this energy to after impact.
