My crazy uncle who doesn't know how your built wants to explain how you work.
"Marriage of Gravity" is one of those terms that was made up in the moment to simplify a more complex idea. Unfortunately, it took hold. One should take the time to enhance his or her understanding on how to generate additional accelaration.
You should want all your students to understand these basic principles at a higher level than "caveman beat stone with stone make fire".
Let's be clear. I'm not getting personal or trying to get on anybody for doing what they do. I'm strictly speaking on the labeling of this particular idea. And the idea that "what is Force" vs. "what the forces in the universe that determine the very construction of it are".
Perhaps Differentiated Vector Quantity due to utilizing the greatest available accelerant generator. F=m(a+x). mass being constant. a being 9.81 m/s2. x being the difference in vector status.
Maybe too wordy. Maybe not smart enough. But, when you start to think in those terms it's more than just dropping your weight, it's using your mass in direction and application. Especially important when you're fighting above your weight.
As for the other three, without them you just wouldn't exist enough to practice Kenpo.
