First, if you look at this forum, at other tennis forums, if you listen to coaches - everybody talks about "loading" energy, more precisely - about adding energies generated in different parts of kinetic chain. This is "your" 5 stage rocket
OK. Do we see this process on the image? Where?
I think I see what you mean. The energies peak in the following sequence before following: LL, Tr, uarm, LArm, then finally H-R. Each causes a transfer to the next component, it seems. That would be the 5 stage rocket, right?
