Victim and attacker, Nice!
 

By way of an apology, John, I won't insult you if you don't insult me by using sarcastic terms and abusing dead people who created a really fine work.


So let me model a nice way to ask your question. Instead of :

Seems strange to me that only during the impact interval does the path of the club have 100% influence on the direction of the ball(down and to the right) and yet at separation it chooses to leave the face practically at right angles. How can Homer have it both ways? While on the face, only path influences ball even though the face is rotating while the ball is on it and the ball's centerlined has moved relative to both the angle of approach and arc of approach as depicted in 2-C-1#3 and this has no effect. Then all of a sudden, the ball decides to stop listening to the path and come off the face at practically right angles.

Some smart ball.

Why not: I'm trying to understand what happens to the ball during the impact interval. It seems like a contradiction to say ..... What factors am I missing? I'm sure Mr. Kelly had a point. I'm not sure if I can follow it this way. who can help?


We are writing about the legacy of a man who has passed on. He trained the man who owns and operates this site. I'm guessing that counts for something and ought to be respected.

It's sort of like me saying that any man who wears a mustache, or puts one in his avatar, or puts the Philly Phanatic or Shaniah Twain in their avatar, must've not been raised properly by his parents. Firstly, I don't believe it. Secondly, it's just damn rude to insult people because you don't understand what they taught their kids as passing for fashion. Something else, too, John. Taking backhanded shots at Mr. Blake is supposed to help all of us and you exactly how?

I'm sorry for leaving out Win McMurray, it will not happen again! :)

This forum is very cool :) where else do you get the chance to learn about this stuff

thanks all

I agree Tim, plus it looks like things have calmed down and everybody is coming to a consensus. Maybe everybody just has to look at impact in the manner that makes them comfortable, just like different components in the stroke.

Wise words from a wise man! :salut:

Which wise man?

I think of impact interval as a circular motion by the club. The motion of the ball is a little more complex I guess. After all, the ball is being quite deformed and doesn't get back to normal shape before it's in the air.

I'm not sure what Homer said about a perfectly straight shot. But based on his impact drawings in ch two, i would say that a straight shot with as perfect as it gets compression would require a vertical hinge. Becaus a horisontal hinge would impose the rotation rate of the hinge itself on the ball. So even though we assume that separation occurs at low poing and club face pointing towards target it will be a small draw. But we are perhaps talking so small that it isn't even measurable.

There could be a little of both here. The part of the ball that sticks to the club face could be carried down and to the right, while the part furthest away from the line of compression move up and towards the inside of the club face. This is just a excample as I know very little about how the ball behaves during impact in detail. But there's no doubt that there is som serious redistribution of mass going on in the ball during impact. Elastic deformation. Of course, how the ball deforms and how it recovers will have an impact on the ball flight.

Pehaps we should talk about elastic deformation, energy storage and elastic recovery instead. I bet the makeup of the ball can make a difference here.

Mr Homer Kelley. :salut:

wise words indeed Kev, i've learnt more in a fortnight on here about what i can do in a golf stroke & why i might choose to do it, than i learnt in 7 years elsewhere & it isn't like i wasn't looking before ! :-)

and the best bit is i'm sure i'm just scratching the surface so far

Oh - that wise man.

My thoughts exactly Tim, I've taught for 30 years+ without having the first clue, I felt like a bank robber, now I'm scratching the surface and just feel like a pick pocket! :) We'll get there...

BTW, I love it when folks type with an accent! :) :salut:

Kevin

gotcha

2 weeks to you :-)

nicely put :-)

i'm sure you aren't picking pockets & you are making up for the bank robbing by giving thoughts & opinions away on here for nowt :)
