Here are videos created by James Ridyard http://www.golfperformancelabs.com that show what the D-Plane would look like for some tour players shots.  These are not an exact representation but I think display the idea very well.

Thank You James.

    Can you please tell me why this matters? seriously, I do not see why anyone other than a physicist would need to know this. It does nothing to my understanding of the golf swing

  2. Jim says:

    or my ability to shape shots, or understand how to shape them. At some point there will be such a loss of power from a glancing blow that this stuff doesn’t matter anyway

    Jim,

    It explains what happened when the club and ball collide with each other. It explains why the ball flies the way it does and why the ball starts where it starts. It explains what needs to happen to work the ball and hit it straight. Does my explanation need further refining? True, it doesn’t tell you how to do either of these things but it will tell you what is happening whether you feel it or not.

    A glancing blow still follows the D Plane also.

    It explains why the ball does what it does based on the club face to plane relationship.

    Understanding it helps you figure what you have to do to make the ball accurately curve a certain way.
