Why have you not repied to my example. You asked me to give you an example. I do, & then you seem to ignore it & do not respond. I guess I'm too 'confused & ingnorant'.
I think for the most part many people are starting to ignore you. I'm not saying that to be mean but you have a tendency to be set in your way as far as your knowledge of the game.
You have a brain for the game but you are lacking the ability to adapt your thinking to grasp new concepts and you look at situations from a limited perspective.
I'm not saying you aren't knowledgable about the game and I'm not saying you aren't a good player. In fact I know nothing about you as a player.
What I am saying is that you are unwilling to adapt and add in new variables to an issue when you encounter them.
I don't pretend to know about the physics of balls colliding as it isn't something I have studied but I can understand why spin does little to alter the course of an object ball.
Because they are round objects they are only making contact at one point. We also know that pool balls don't have any 'give' upon contact.
Depending on the force of the contact the contact time will change. If a ball is in contact with the object ball for longer (ie, a softer shot) there will be more opportunity for the spin to translate to the object ball.
I do agree that the softer the shot the more spin is transferred because the more contact time there is but I also think the spin translated is negligble at any speed because pool balls don't 'give' upon contact.
There are other factors that would play a part in this however such as if the balls were dirty or pitted from extended use.
If the balls are dirty or pitted I imagine there is more surface area upon which the spin can transfer.
The thing that you are having difficulty with is that pure mathematics do not always translate to the real world. There are too many factors involved and more often than not some unknown variable in the real world will change the way something behaves.
Don't take this as proof that your theories are correct however. You have to look deeper into the problem and figure out what variable is changing the outcome.
Also, work on your combativeness. It is putting off quite a few people and there are other, better, more diplomatic ways of debating and communicating your thoughts. I can tell you are angry and acting out of defense but take a step back before you do and think of a better way to phrase things sometimes.
As to your example about cutting a ball with spin- I believe that the direction a cueball is travelling as it relates to the point of contact will alter the course of the object ball. I do not think that cutting the ball with spin will alter the path of the object ball any more than cutting the same ball without any spin.
