John does an excellent job explaining the D-plane concept by using a triangular shaped piece of cardboard to represent the D-plane. It tells us what your club is doing at the all important moment of impact, as well as tracking the full flight of the ball, which then allows us to figure understand the golf balls flight.
In general, a higher spin loft will produce more spin and will tilt the spin axis into a more neutral position. Consider the three dotted ball flight patterns on the left.
On grass you can check your divots to determine your swing path see below. However, that combination-choice would not produce his desired result! If you want to fix these shots — read on Out with the old, in with the new There has been lots of debate recently in the last 7 years or so on which ball flight laws are correct.
In the above picture, the clubface is open more right of the path. It may just mean that an unintentional off-center heel strike made his ball go straighter in that particular shot, and that could be a chance-event that may not be consistently repeatable.
But your swing path line must also be severely out-to-in. Above scenario 5 we see a student impacting the ball with a face angle that is 5. The work done by physicist Alistair Cochran was certainly not in vain though. The next question must be then, what are the The factors of ball flight to an inside-straight-inside swing path?
If the trailing edge were rounded, the higher-pressure air flowing along the lower side would try to follow the rounded surface and spill upward into the lower-pressure air above the wing. What Causes Side Spin?
In conclusion, the easiest way to understand your golf balls flight, and impact parameters, is to remember that the club face will determine the start direction and the ball will curve away from the club path in relation to the start line.
If the clubface also faces the target at impact, then the ball will go straight towards the target - because both the clubhead path and clubface orientation are directed towards the target at impact. A ball that starts right and finishes further right is called a push-slice.
Direction Simplified Another definition I like to use is the following If the face is more right of open to the path, the ball will curve right. Producing the optimal angle of approach will maximise launch conditions spin rate and launch angle and optimise the distance the shot goes Curvature and direction As previously stated Energy is transferred from the club head into both forward momentum and ball rotation.
Therefore, the two figures cancel-out - thus explaining why the ball will land very close to the target by yards. My top drill for building up this awareness and skill at the same time is to Mark the golf ball with a dot of ink from a dry erase market pen Line the dot up to the back of the ball and hit You will leave a mark on the clubface as to where the ball contacted the face Wipe off — repeat Through doing this drill, you will start to develop a much better feel and will be able to identify the strike without even seeing the mark eventually.
The best method of assessing the clubface orientation is to use a magnetic lie angle tool. The ball will take-off slightly to the right-of-the-target line, and curve slightly leftwards due to the presence of a small amount of draw spin due to the fact that the clubface is slightly closed to the clubhead path at impact.
We see that this student has just hit a great shot Scenario 4 Part A. It then displays the shots 3D trajectory as well as 26 impact and ball flight parameters in real time.
Low point is at the nadir of the clubhead arc. Note that the ball will start off in a take-off direction that is directed slightly to the right of the ball-target line, but it will still hook violently to the left.
In image 2, John Graham demonstrates that the clubhead arc must be slanted to the right, to get the tangent line to the clubhead path a few inches after low point to face the target at impact red arrow.
Players never seemed to be inhibited too much by the old inaccurate information. The clubface was definitely open in relation to swing path and target line.
Set up so that your feet, hips and shoulders aim to the right of your finishing target i. This golfer should realise that his primary problem is a closed clubface at impact problem, and not a clubhead swing path problem.
I will discuss some of his video presentation examples - and in my explanations I am going to presume that the clubhead attack angle is always zero and that the ball is always hit on the sweetspot. A ball that starts right and finishes further right is called a push-slice.
That combination would produce a ball flight where the ball starts off just to the left-of the ball-target line, and fades back to the center ball-target line later in its ball flight.
Mentally picturing the D-plane in a 3-D perspective In this capture image from the Dunigan swing video, the clubhead path yellow stick is directed left of the ball-target line white stick. Diagram depicting the 3-D alignment of the D-plane for a push-draw shot - diagram created by Mandrin The ball target line is between O and E.
This ball flight ensures they split fairways from the tee and can attack tight flags which inevitably leads to low scoring. The lie angle tool rod which portrays the direction of the clubface orientation is directed along the ball-target line.
Just like launch direction is mainly influenced by the face angle, the loft produced at impact will largely dictate where the ball launches. Again, there are only ever 3 possible club face angles relative to the swing path for that particular swing: This table also brings up another important point.
If the clubface is open to an in-to-square-to-in clubhead path, then the result will be a slice.Stop Guessing about your ball flight What are the main factors in ball flight curvature and distance? Ball curvature and distance control are key to any great iron shots as we all know, but let’s truly understand how the club is influencing the golf ball.
Golf Science: Golf Ball Flight Laws. By. Jon Levy - Aug 5, Facebook. Twitter. Pinterest. WhatsApp. Linkedin. check out the GolfTEC Scramble daily and Golftec’s site illustrated what factors go into your ball flight after striking it.
This is the best, simply illustrated explanation on what is causing your ball to do what. And learning the basics of ball flight is very easy - it takes just a minute or two to grasp the simplest, most common explanations for why the golf ball does what it does." Having the most basic understanding of ball flight cause-and-effect lets every golfer do his or her own coaching.
Through research, science has determined that the ball will start its flight perpendicular to the faces angle. For a right handed golfer, an open club face (cause) produces a golf ball to start to the right (effect) of the club heads path and a closed club face (cause) produces a.
The "new" ball flight laws are based on the "fact" that the ball's flight pattern is primarily dependent on the clubface orientation at impact, and that approximately 85% of the ball's initial flight direction is determined by the clubface orientation while only 15% of the initial flight direction is.
An airliner wing may produce a pound of lift per square inch in level flight.
That doesn't seem like much, but over the entire surface of the wings these pounds-per-square-inch add up. The wings of a Boeing have a surface area of about square meters (5, square feet) and can produce as much as tons (, pounds) of lift.Download
