I am interested in conducting some personal research on Newton's Third Law of Physics and its application to how body structure is an important part of a powerful strike. My interest is in broadening my intuitive understanding of this concept so I can better explain it to students. In other words, I can feel it and have no doubt about the importance of good structure but want to be able to explain it clearly at a more theoretical and detailed level. Most of the online resources that I have been able to locate seem to equate Newton's Third Law with either the collision of forces moving in opposite directions or the pulling back of hikite to generate forward force in the punching arm. Both of these miss the point for me, which is how a strong structure can facilitate a stronger technique by being better able to absorb the resulting force of a strike.
Can anyone recommend some good resources to review on this point? Chris Denwood covers it in his book on Naihanchi which I have read but am looking for other sources.
