Suresh you always go back to physics. I'm sure even your messiah "neo" aka john yandel does not use exact scientific language to express all tennis to his students. When neo says to his junior player try to extend the fh out a little bit more for more pace and hit it on the rise. Does he quantify the instruction by adding the extention is on a curve and the arc of the curve is ... etc. ... ? No. He just says extend a bit more into the shot. Your hung up on words and descriptions that do not need a exact computer modeled simulation. Its tennis. Your lack of tennis knowledge is so huge as shown by other posters here. And your ignorance and persistent posting of lame brained observations wear people out.
