Facters of deciding the launching direction

This is an ordinary story. But since I started a golf from year 2006, I believed wrong theory. It makes so many problem on me.

It's very important to hit a ball with proper impact and to fly a ball straight in a proper direction. So I write this.

Facters of deciding the launching direction are:

1. The face angle at impact: 80 ~ 90%

2. The vector of head at impact: 10 ~ 20%



At first when I learnt a golf from instructor, she handed a memo to me. It said: 1. The vecter of head at impact defines the launching direction. 2. The face angle against for the vector at impact defines the side rotation. Means hook or slice.

This is old theory.

To say radically, it's wrong in a physics.

When I say this, many people may complain me. (^^;;

Mr. ma6066 taught this to me in a comment in my blog. Thanks ma6066-san !
Can you see ? The direction of launching of ball is following a face angle, not related to the vector of head.

Please note it in your mind.

1. The face angle at impact defines the launching direction.

2. If the vector is in-side-out against for that face angle, then the ball becomes hook. If the vector is out-side-in against for that face angle, then the ball becomes slice.

Please be care full about the order.
Following theory is WRONG !!
1. The face vector at impact defines the launching direction.

2. If the face is close against for that vector, then the ball becomes hook. If the face is open against for that vector, then the ball becomes slice.
If the face angle is square against for the vector, the result is same in above two theories. The ball will be complete straight.

But if they are not square, the launching direction is different in those theories, so the way to hit not straight ball is different in those two theories.

If you rely on wrong theory, you may spend meaningless time like me. (T_T)
