It's the other way around, and I disagree, an open clubface will not produce a fade, but a slice.

Am I crazy here? Can any physics majors weigh in here???

With the laws of physics in mind, how can a clubface pointing in one direction send a ball starting in another direction?? The ball always starts in the direction the club is pointing!! I agree that it starts curving immediately if there is any sidespin (which I still contend is caused by the swingpath ), and because of that it seems like the ball doesn't start flying exactly where the club was pointing at impact, but the laws of physics contend that it did. If you were to lay it out as a physics problem, the initial direction is where the club was pointing at impact. With that initial direction in mind, you adjust the observed direction of the ballflight to include the effect of sidespin. Can someone with some physics credentials please weight in here! I feel like I am losing my mind.

Hi laxbballgolf,

I'm not a physics major, though did take a number of physics courses....I can try and explain the physics with diagrams but before I do that how about I try to convince you by painting a picture in your mind. Imagine you are right handed and your eyes are right above a ball that is being struck. When looking down, lets imagine the ball having the numbers of a clock on it, with the the 3 o'clock position being where the initial impact of the club face would be with the ball if the club is being swung down the target line. Assume the club face is square, hence the ball would travel to the 9 o'clock position. With an out-to-in swing the initial contact with the ball is approximately (relatively) at the 2 o'clock position. If the club face is facing parallel to the swing plane the only resulting vector is the ball travelling left of the target line (assume no gravity). With the same out-to-in case, if the face happens to be open, there are now 2 vectors. One sending the ball to the left (because the ball is being struck at the 2 o'clock) as a result of the swing path and one vector sending the ball to the right (because of the open face). But because the force is greater along the path than along the club face line, the resultant is the ball starting left. The open face puts a clockwise spin on the ball so that it bends to the right. I'm not sure if thats clear....hopefully it helps

Hi laxbballgolf,

I understand and I still disagree.

I think what you are describing (an open clubface at impact combined with an out to in swingpath) produces a push-slice. Here's what I think: Square face + straight swingpath = straight Square face + out to in swingpath = fade Square face + in to out swingpath = draw Open face + straight swingpath = push fade Open face + out to in swingpath = push slice Open face + in to out swingpath = push (or push draw if swingpath is extreme) Closed face + straight swingpath = pull draw Closed face + out to in swingpath = pull (or pull fade if swingpath is extreme) Closed face + in to out swingpath = pull hook The ones in italics have two opposing forces working against each other, so the ball flight depends on which force is more extreme, the clubface angle or the swing path. Sometimes they cancel each other out equally and the ball flies straight in the direction the club was pointing at impact. Bottom line: A closed clubface makes the ball draw, an open clubface makes it fade, an in to our swingpath makes it draw, and an out to in swingpath makes it fade. There are various possible combinations. And I still think the ball starts flying in the direction the clubface was pointing at impact. By push and pull I just mean in relationship to where your stance is pointing. I realize that you can open or close the clubface on purpose which means it's not really a push or pull at all.

Maybe some of the confusion is based on our definitions...

when you describe the club face are you doing so relative to the swing path or relative to the target line? I believe an in-to-out path and square face (relative to path but open relative to target line) will result in a ball travelling in a straight line but to the right of the target (for a right handed golfer).

Square face + in to out swingpath = draw

Closed face + straight swingpath = pull draw


So then based on what you have said above...how do these two ball flights differ?

I say the first starts right of the target and draws left. While the second would start straight but would quickly start turning left of the target.

Maybe I'm wrong, but I say the first starts straight at the target and draws left, while the second starts left of the target and draws further left.

Hmm...so at least we both agree they both go left

Well maybe the next time at the range test it...I know its what I have found. I like trying the exaggerations of each and then working my way back to neutral for both path and face. Hopefully I've been correct in my thinking based on what I've been hoping to do...coz if not it's gonna take alot or "relearning" hahaha

I'm talking relative to the target line, always. First, let me give you an example.

Have you ever read or heard or been told how to intentionally draw or fade the ball? Most will tell you to set up square, then open or close your stance a bit with the clubface still aiming at the target. This will launch the ball in either direction and put a spin on it so it will come back to the target.

Go out and test this yourself. You may not get it right all the time, but you should be able to see for yourself. The driver may be the easiest one. Tee up the ball, choke down on your club, set up square then close or open the club with your grip. Now you are set up, clubface facing left or right, feet and shoulders facing straight ahead. Give the ball a wack with a nice and easy swing and make sure you swing straight. You need some speed for it to get the right curve. The ball will start out straight, but with the clubface open or closed it will create sidespin and curve to either side.

It's the same with a football, or any other ball for that matter. If you want to curve a ball from outside the goal to inside it, you takeaim outside the goal and at impact twist the foot so it points at the goal, but the foot still travelling on a path going outside. With enough power, it will launch the ball outside and curve it back on the goal.

Here's a link that maybe explain it better:

Square face + in to out swingpath = draw

The correct is:

Square face + in to out swingpath = draw = will start out to the right and spin back onto the target Closed face + straight swingpath = hook = will start out straight and spin to the left Hook = closed clubface Slice = open clubface Pull = out to in swingpath (over the top) Push = in to out swingpath Combine any of these with square and you've got 9 different flight patterns.

This guy thinks you're right, maybe you are and I'm wrong.

Hi Evan,

A draw if a ball flight that curves slightly right to left (for a right handed swinger). A slight sidespin is imparted onto the ball due to the club face being slightly closed relative to it's swing path. The path the ball starts out on is dependent on the swing path.

When in flight, the sidespin results in more air passing across the left hand side of the ball, thus lowering the air pressure on that side (Bernoulli Effect). The result is a force the pushes the ball to the left.

Hope this helps. If you need further explanation, contact me at probablegolf@yahoo.ca

I agree with your #2 but I think your #1 is meant to say "right" instead of "left"

Lax,

Go to any golf course in the country and you will see the following... golfers with a grooved slice swinging left, starting the ball left, and curving it right back in the fairway. I used to be one of those guys. I started swinging left (over-the-top, out-to-in) because my club face was always open and the ball always curved right. Aiming left (or swinging left) was the only way I could compensate for it and keep it in the fairway.

My divots pointed way left of the target. And if there were trees on the left side of the fairway, my ball would clip the branches before curving back to the right.

Your club doesn't know where your feet are aligned. Aligning your feet toward the target and swinging left with an open club face is the same as pointing your feet left and swinging straight (in the direction your feet are aligned, left of the target) with an open club face. Both will start the ball left and curve it back to the right.

You are confusing cause and effect. Swinging left (out-to-in) does not cause a slice. It is something that golfers with a slice adopt in order to compensate for their slice.

Because the ball compresses on the clubface and is "carried" in the direction of the swing path.

Now, these ball flight laws (ball starts in direction of swing path, curves based on face angle relative to that swing path) only apply to clubs with lower loft and swung with enough speed. For most people, it's a 5-iron on down. You have to compress the ball. Once you get into a 6-iron or higher, the swing speed and high loft don't allow the compression to take place as much and the face angle will start to take over in determining the ball's starting line. Also, the advice only really works for angles of ten degrees or less (or so): if you open your driver 30 degrees and swing straight down the target line, the ball will start right. Not a full 30 degrees right, but it won't be straight down the target line, either. P.S. The ball always spins based on the face angle relative to the swing path. With a face square to the swing path, the ball goes straight: it may be a push, pull, or a shot at the target, but it'll go straight.

Lax,

A, yes it does because an out to in swingpath imparts spin on the ball . Just like in other sport the club face dragging from right to left puts left to right spin *facing ball* on the ball making it slice. Same thing happens in tennis, pingpong baseball. The racquet can be perfectly square but if it is moving in a direction it imparts spin curving the ball in the opposite direction.

    • In driving a car you have all sorts of random or variable parts, though. Different speeds, corners, conditions, size of turns… even different cars and sizes, different traffic and laws (lights, signs, etc.). I don't think I've seen anyone doing "block practice" to practice the same exact turn 100 times, then trying it in the real world.
    • IMHO, block practice is good. Any new motor pattern or a 'move' has to be committed to muscle memory and be reproducable at command without conscious thought as the final goal. I don't see how this is that much different than learning how to drive a car, or let's say how to handle the steering for example. One must do it enough times and then also do it in different situations to commit to all layers of brain - judgment of demand, decision making, judgment of response and finally execution. Unless each layer is familiar of each of their role in the specific motor move, it is not truly learned and you will simply fall back to the original pattern. I think the random practice is simply committing the learned pattern to different scenarios or intervals of time to replicate in the real world (actual rounds). It breeds further familiarity learned from block practice. Steer the car a hundred times to learn the move (block) and then drive the car all over town to make it real world (random) to a level of maturity. I don't see how block and random have to be in conflict with each other.  
    • Yea, I think the first thing is to define block, variable, and random practice with regards to golf.  The easiest one might be in practicing distance control for putting. Block practice would be just hitting 50 putts from 5 feet, then 50 putts from 10 ft then 50 putts from 15 ft. While random practice would having a different distance putt for every putt.  In terms of learning a new motor pattern, like let's say you want to make sure the clubhead goes outside the hands in the backswing. I am not sure how to structure random practice. Maybe block practice is just making the same 100 movements over and over again. I don't get how a random practice is structured for something like learning a new motor pattern for the golf swing.  Like, if a NFL QB needs to work on their throw. They want to get the ball higher above the shoulder. How would random practice be structured? Would they just need someone there to say, yes or no for feedback? That way the QB can go through an assortment of passing drills and throws trying to get the wright throwing motion?  For me, how do you structure the feedback and be time effective. Let's say you want to work on the club path in the backswing. You go out to the course to get some random practice. Do you need to set up the camera at each spot, check after each shot to make it random?  I know that feedback is also a HUGE part of learning. I could say, I went to the golf course and worked on my swing. If I made 40 golf swings on the course, what if none of them were good reps because I couldn't get any feedback? What if I regressed? 
    • I found it odd that both Drs. (Raymond Prior and Greg Rose) in their separate videos gave the same exact math problem (23 x 12), and both made the point of comparing block practice to solving the same exact math problem (23 x 12) over and over again. But I've made the point that when you are learning your multiplication tables… you do a bunch of similar multiplications over and over again. You do 7 x 8, then 9 x 4, then 3 x 5, then 2 x 6, and so on. So, I think when golf instructors talk about block practice, they're really not understanding what it actually is, and they're assuming that someone trying to kinda do the same thing is block practice, but when Dr. Raymond Prior said on my podcast that what I was describing was variable practice… then… well, that changes things. It changes the results of everything you've heard about how "block" practice is bad (or ineffective).
    • Day 121 12-11 Practice session this morning. Slowing the swing down. 3/4 swings, Getting to lead side better, trying to feel more in sync with swing. Hit foam balls. Good session overall.
