Understanding the “NEW” ball flight laws

Published

on

Over the last several years, golf instruction has gone through a unique transformation. The advent of 3D motion analysis, video, and ball/club flight launch monitors have proven to golf instructors that some of the “fundamentals” we were taught by our mentors were incorrect.

With the advent of Trackman and Flightscope, advanced Doppler radar launch monitors that cost upward of $10,000, we are now able to understand what actually happens during the impact interval. This has made golf instruction much simpler as a result.

Students are now learning improved fundamental motions in their own way, while instructors are not so much focused on the complex mechanics of the swing itself. For the facilities that have a Doppler radar launch monitors, such as Promontory, our students are learning under the guise of the “in my own way,” not “ in this way” type of golf instruction.

Trackman and Flightscope provide video-based instruction coupled with the data of club and ball interaction, thus correlating exactly what is going on during the swing. Think of this new technology as providing your instructor with a MRI of your current fundamentals so you both can focus on facts, not opinions.

One of the most important things Doppler launch monitors have given us are the “new” ball flight laws. In the past, golfers were taught that the ball begins in the direction of a club’s path, and the curvature of the ball was due to the face angle at impact. Now, we know that this line of thinking is 100 percent INCORRECT.

In fact, the face angle at impact determines 75 percent or more of the ball’s starting direction, and at slower ball speeds it creeps up to almost 100 percent. This has made curving the ball much easier to understand for my students, and below are examples of this fact all backed up by the data that the my Trackman system shows for each shot.

Example 1: Hitting a Fade

Screen Shot 2013-06-13 at 11.46.25 AM

In Example 1, I am hitting the ball left to right, or fading the ball for a right-handed player.

  • The solid white line represents my target-line (directly at the flag in the distance).
  • The blue line shows the path of the club (negative numbers are out to in).
  • The red line determines the direction that my club face was pointing during impact (negative numbers mean a closed face).

You can see by the purple line that this ball began slightly left of my target (3.5 degrees left of my target-line) and faded 34.9 feet to the right of my intended target. This proves that when the path is left of the face angle (provide a centered hit on the club face), you will hit the ball left to right. Thus, if you want to move the ball left to right (for the right-handed player), you MUST have your face open to the club’s path.

NOTE: I said that the club face must be pointing to the right of the club’s path in order to hit a fade, not open to the target line.

My path was 6.6 degrees from out to in (Example 1), my face was 2.6-degrees closed and the ball moved from left to right. Yes, it moved left to right WITH A CLOSED FACE! If my club face had been open 2.6 degrees, then the ball would have curved exaggeratedly to the right. But in this case, there was only a 4 degree path to face differential — the lower that number the less the curvature. That’s why the ball only faded a small amount to the right.

Example 2: Hitting a Draw

Screen Shot 2013-06-13 at 11.46.44 AM

In Example 2, I am hitting the ball right to left, or drawing the ball for a right-handed player.

  • The solid white line represents my target-line (directly at the flag in the distance).
  • The blue line shows the path of the club (positive numbers denote from inside to the outside).
  • The red line determines the direction that my club face was pointing during impact (negative numbers mean a closed face).

You can see by the purple line that this ball began down the target line (launch direction is 0), while my face was 1-degree closed. These conditions started the ball at my target, and moved it right to left 55.4 feet.

As you can see in Example 2, when the path is right of the face angle at impact, you will hit the ball right to left (provide a centered hit). The ball flight began very close to the face angle as described above. Thus, if you want to move the ball right to left (for the right-handed player) you MUST have your face closed to the club’s path.

NOTE: I said closed to the relative path, NOT closed to the target line. That brings me to my next point about the shot in Example 2. 

You can see that my face-to-path ratio was -6.4 degrees, which means that my club face was 6.4 degrees closed relative to my path’s direction. This is why my ball started at the target and then moved left of it instead of starting right of my target and drawing back to the target.

There is a huge misconception that you must have a closed face to draw the golf ball, when in fact all you need to do is have your club face pointed left of your path. So in Example 2, if my face was more open at impact (let’s so 1 to 3 degrees), then you would have seen the ball start to the right and curve to the target — not to the left of the target as mine did in this example.

The golf swings thoughts above might seem complex due to the numbers involved, but the bottom line for you at home is to do the following:

To Hit a Fade

In order to move the ball left to right, you will need a path that is more left than the face is pointing. So if you keep the club face pointing right of the path it will curve from left to right

To Hit a Draw

Understand that in order to move the ball right to left, you must have a path that is more “in to out” than where your club face points at impact.  Another way to think of it is to have the face pointing left of your club’s path — this will allow the ball to move right to left

    This info is as John Jacobs describe for years and years. You’re just proving him right. Swing left go left, swing right go right, swing square go square. Then face angle RELATIVE TO PATH determines ball flight. And all this info has same purpose, control the ball and learn fundamentals to do so. Geesh, same old same old, but now we have new tech to see what our body did as we swung.

    “My path was 6.6 degrees from out to in (Example 1), my face was 2.6-degrees closed and the ball moved from left to right. Yes, it moved left to right WITH A CLOSED FACE!” – Closed relative to the target line or closed relative to the swing path? – I know this article is old, but really hope you reply.

      I’m just another poster, but I am sure he means closed relative to the target line. The face is 4 degrees open to the swing path, but 2.6 degrees closed to the target line.

    Way too much confusion on target line and path. I was taught over 20 years ago that club face has to be closed relative to path for the ball to move right to left (right handed golfer) the clubface must be open relative to path for the ball to move right to left (right handed player). This really isn’t new information just that new technology makes it easier to see. As long as your club face is square to your path you will hit the ball straight, but it could be straight left or straight right.

    so much confusion comes from people not having the same definition of a draw and fade. some say a draw or fade starts on the target line and then (for a rh player) will draw to the right of the line or fade to the left of it. others say the ball should start right of the target line and draw back to the line or start left of the target line and fade back onto it. the second example i think should be considered a pull fade or push draw, this is what sean foley teaches. a lot of it comes down to what you are more comfortable using as your target line.

    I am glad that articles like this continue to be written as there are still a great deal of people who still either have not been exposed to the correct information or have not quite grasped it fully yet. It is so important for this information to be understood.

    Clubface starts the ball, path curves the ball.

    Guys, does anyone know an official link (e.g. PGA) where above is stated ? I realised most teachers cite the older books where it says the path determines the direction and the face the curve. It’s very hard to come by unless you have something official..

    The ball generally starts down your path and finishes where the face is pointed. Your path should be parallel with your stance/line of your toes. Align your toes with where you want the ball to start and adjust the face to where you want the ball to finish. Take your normal swing. Simple (in general).

      that’s actually incorrect. The ball starts, depending on iron or driver, 80% or more in the direction that the face angle is pointing at impact, not the path. The ball curves away from the path relative to the face.

      That’s how I used to think. I think I’ll have to go prove this out on the range again.

    To hit a draw you must have the club open to the target and closed to the path. A draw must start right of the target and finish on it, this is not possible without the club face being open to the intended target

    Great Stuff. Very informative article leaving out all the subjective crap, Johnny Miller and other idiots on TV need to read stuff like this. Not saying he was not a good golfer, but some of the stuff that spews from his mouth regarding the swing is Madness.

    I think a big issue in this teaching divide is the semantics– that is, the definition of “draw” and “fade.” Most on this site get that both shots are designed to fall onto the desired target (positive end result) as a result of curvature from either side.

    However… I can cite many written and verbal examples of teachers/players, usually older, who will describe a draw as beginning at target and bending left and a fade being the direct opposite (so essentially a pull hook or block fade). They’re usually the guys who will tell me: “jeez, if you hit it where you were aiming (the line of my stance) you’d be into those houses way over yonder…”

    Almost forgot…. the easiest and quickest way to explain the ball flight: the ball starts generally at the direction the face is pointing at impact, and curves away from the path.

    Quote: “There is a huge misconception that you must have a closed face to draw the golf ball, when in fact all you need to do is have your club face pointed left of your path.”

    I think the problem here is that people either confuse or mix up ‘path’ and ‘target line’, as in the face open/closed to the path, or face open/closed to the target line. The ball only knows the path, it has no idea of where the target is.

    So with that, club face left of the path would be closed in reference to the path, and I think people confuse that with the idea that they need the face closed to the target line.

    All of which likely explains why slicers think they need to aim farther left, and in turn end up slicing the ball even harder. The mind has a hard time wrapping itself around this crazy game of opposites where if you want to keep the ball from going right, you must set up to the right.

    As a recent Golf Academy of America graduate I am opening my own club fitting, repair and teaching facility. With retail goods as well. My question is, “What is the best teaching software/simulator on the market for the least amount of money?” I will be putting in a full size simulator but I want to get spot on readings to help my students with.
    Thanks for your help, Bill

      Your two best systems are Flightscope and Trackman. Flightscope is cheaper.

    Could you post a picture of how the club face should look like at impact?

Shawn Clement: Dealing with injuries in your golf swing, lead side.

Published

Happy Father’s Day weekend and U.S. Open weekend at none other than Pebble Beach weekend! Whoa, cannot wait to see the golf action today!

In this video, we talk about how to deal with hip, knee and ankle injuries to your lead side as this one is PIVOTAL (pardon the pun) to the success of any kinetic chain in a human. This kinetic chain is a golf swing. Now, what most of you don’t get is that you were born with action; like a dolphin was born to swim. Just watch 2-year-olds swinging a club! You wish you had that swing and guess what, it is in there. But you keep hiding it trying to hit the ball and being careful to manipulate the club into positions that are absolutely, positively sure to snuff out this action.
