  • In an ideal world a video like this would be made indoors, with a robot arm. But, until that happens, I thought I'll give it a try. I was pretty surprised by the results honestly. I didn't think that the different discs would actually make a difference for really slow throws. But they do. My next video should be how to throw a disc properly. I just need to figure out how to teach that... hmm.

    Hey Simon, Danny Lindahl has a good (quite recent iirc) video on nose-angle, and how the added air resistance from a nose-up shot slows a driver down proportionally a lot more, than a nose-up putter would. Basically even a slight nose-up angle on a driver easily doubles the frontal area of a slim disc, where as a thicker putter with a similar nose-up angle wouldn't "grow" as much.
    I think that's why you guys saw such a big difference with drivers, while putters being more equal. And as you already deducted, spin obviously stabilises the flight, and fights against both an aggressive turn and fade. Straighter further, spin good.
    We can't of course figure out all specific factors in these specific shots from this video, so there's always thousands of small things and not one simple fix. I do however believe that nose-angle is the simplest, biggest factor in these situations.
    At least, that's what I've observed and learned over the years. Good thought-provoking video, thanks Simon. I hope more people get interested in the actual physics of what's going on. For most of us normies there is a lot of non-power related potential to be unlocked.

    • @discgolfdetails9889
      @discgolfdetails9889 3 роки тому +1

      The putter is less prone to nose angle as well with it's blunt edge. You can throw a putter a little nose up and it won't change the distance much. Also I'm not sure if Simon power gripped his putter shot compared to the other guy (sorry I forgot his name). That will effect the amount of spin on a shot, compared to a fan grip.
      Spin and nose angle are the biggest factors. For instance a FH shot is nearly always going to be lower spin then a BH shot. So it will fade sooner and drop out of the air quicker.
      Discs can also have wobble or Off Axis Torque. If one disc is wobbling even slightly more then another it will not be as aerodynamic through the air. With a putter or Mid this will also be a less of a factor since they are not as sensitive to the aerodynamics. Then of course spin is going to stabilize the disc as well even if it's slightly wobbling, so higher spin is another benefit so the disc flies more aerodynamically optimal.

  • @Tsukmu

    It probably has a lot to do with angle control and the spin. I have noticed that Garrett Gurthie almost always measures less MPH than if you say Eagle does, but seems to throw it almost as far.
    Maybe his unique form generates more spin than the others, so he can throw further with less speed. Of course he has world class distance lines, but still, seems interesting topic to make more tests.

      I dont think spin equates to distance actually, more spin means more stability which would mean less distance, I think there is a perfect threshold of enough spin for the disc to fly smooth and consistent and then too much spin to where you start losing distance because of added stability. I remember when I first started playing I thought I had lots of power because I was turning over firebirds, but it's just because they were coming out with little spin, a little wobbly and the added turbulence would turn them over. Once I started throwing smoother and with more spin, less wobble, I actually lost quite a bit of distance for a bit because I was no longer getting the turn out of those stable discs

      Part of the difference in Simon’s vs Raivus throws has to do with everything that happens at the end just prior to & during the release.
      1) higher rotation speed from the Snap/spin allows greater benefit from the bournoulli principal acting on the rotating disc which helps keep it “floating” in the air longer. (faster spin = longer forward flight, postponing the stall. More easily noticed when you try to throw an anhyzer putter shot a short distance. If you don’t put enough spin on the disc, it stalls out from moving forward well before it finishes the flight time in the air - hyzering out short.)
      2) Smooth release technique: A smoother release helps reduce wobble which adds friction during flight, slowing the disc in flight.
      3) release angle(s) - perpendicular rotation: a slight hyzer with a high speed wrist snap allows for a flip-flat flight/helix flight path.
      Horizontal rotation: nose up = quicker stall and fall and possible wobble depending on the release. Also swing motion can accentuate that with an air-bounce type motion from reach back to follow thru.
      4) Grip: all of the above relies on the benefit of a well executed/consistent grip & release.

  • @denoument84
    @denoument84 3 роки тому +93

    Spin resists change in disc orientation relative to the trajectory. The angle the disc is thrown 5-10 degrees above horizon is the key for optimal distance. I'm sure each disc has a specific optimal angle. Angle of attack changes the air resistance presented to the disc.
    Also each disc presents a different frontal area when traveling up than when traveling back to earth. For the high speed portion the disc has a tiny silhouette presented to the air stream but as it starts to fall to earth it presents a bigger silhouette to the air acting like a parachute I guess.
    Try filming perpendicular to the disc trajectory to see the affect the trajectory has on each disc.

      @MaxLBogue 3 роки тому +14

      The more concentrated the weight is towards the outer edge of the disc, the more it will act like a flywheel with high rotational inertia, resisting forces that try to push it off of its initial plane. Putters and midranges are, thus, more resistant to their pitch and roll changing due to turn and fade, the precessional forces due to the upward forces at the nose of the disc and towards the tail. The effect of these forces is felt on the left and right sides of the disc rather than the back and front due to the spin of the disc and how the acceleration adds velocity to the spinning system.
      Wider-rimmed discs will have greater fade due, generally, to the redirectional shape of the nose of the disc as well as their lower rotational inertia. However, having lower resistance to changing the plane of the disc also means that drivers precess more due to the downward airflow at the tail of the disc, or turn, and their ability to maintain faster airspeed for longer contributes to this airflow and a longer turning line. Overall, discs with wider rims will tend to fly with less neutrality, turning more at the highest speeds and fading more at the lower ones. This is evident in the fact that putters and midranges finish, at low speeds, much straighter than drivers. This can also be seen in the video around 11:15 where he throws the P2 quite flat, and it shows a very straight path with little flip and fade, whereas the DD3 clearly flips up from hyzer at a lower release speed and fades hard.
      The difference in distance really is due to the difference in cross-sectional area. Putters displace the most air, which means they can glide at the slowest speeds, but it also means they lose much more energy to drag at higher speeds. This is also why popped up versions of discs are more glidey: they displace slightly more air than flat-top discs, which allows them to generate more downward lifting force after that air flows off the tail of the disc, but also increases their drag at all speeds. That greater drag slows the disc down faster, and slow-moving drivers fade, so this is why poppy discs generally feel more overstable.

    • @snikwahjets
      @snikwahjets 3 роки тому +7

      @@MaxLBogue HI max I liked most of what you said. But for wide rim disc the neutrality depends on rim shape not just rim length.
      Extreme overstable discs like the Tilt have a flatter tops with a high parting line. This results in the lift being forward of center which wants to "Tilt" the disc nose up. But the disc is spinning so the disc Tilts to the left (BH)
      Understable discs have a low parting line and are often domey.
      This results in the lift backward of center which wants to "Tilt" the disc nose down but the disc it spinning so the disc Tilts to the right (BH)
      Neutral discs have a center of lift at the center of gravity so there is no tilt.
      However as discs slow down the angle of attack changes which move the center on lift forward.
      Which is why they fly more overstable with a noodle arm or at the end of flight and fade.
      Discs like the Nova and most slow discs have more consistent netrality over a range of angle of attacks so you don't see much fade and the end of flight.
      Decreasing spin near the end of flight also adds to the increased fade.

    • @MaxLBogue
      @MaxLBogue 3 роки тому +9

      @@snikwahjets Yes, rim shape is important. Overstable discs with high parting lines will push far more air down at the front, causing an upward force on the nose and early fade at high speeds due to the precession of that force 90 degrees towards the direction of spin. Similarly, understable discs with low parting lines will cause more air to flow downwards at the tail of the disc due to the no-slip condition, causing a greater lifting force on the tail which precesses towards the direction of spin causing turn. Neutral discs have a balance of these two forces, and slower discs can be more neutral as I mentioned due to their greater gyroscopic stability. Spin decrease is negligible; the biggest reason for fade at the end of the flight is that the disc has begun to move downwards, pushing the bottom of the leading rim onto the air with an equal and opposite force pushing back up, with the precession of said upwards force causing fade. Overstable discs are designed to take advantage of this effect throughout the whole flight with their rims that direct most of the air downwards, but you'll notice discs of all stability levels will have rims directing airflow in different ways to balance out their lifting forces. Again, putters and midranges have less fade even when dropping at the end of their flight partially due to the decreased lifting area of the front of the rim on such discs, but mostly due to their increased gyroscopic stability. Catch discs like the Discraft Ultrastar take this to an extreme, given that they have an unbeveled edge; there is barely any lifting surface on the front rim to cause fade, so they are normally very true to their angle on the descent.

    4:28 The midrange going shorter than the putter isn't surprising; I'm more surprised that you didn't get more results like that. I think it speaks to your consistency and precision that that only happened once. All of these are thrown at slightly different speeds, heights, and hyzer angles, so you're going to get a fairly wide data range. Also, you have a sample size of 1 with each combination of disc and arm speed which is going to add a TON of variance. You can cut your standard deviation down by about a third by just throwing 2 of each combination and averaging them, or about 50% by throwing 4 (standard deviation decreases proportional to the square root of sample size when you're averaging the results) which would give you more reliable results.
    To explain the different distance changes at different velocities, it's probably relevant that air friction is jointly proportional to the area of the face and the square of the velocity, which means that at low speeds the effect of being more aerodynamic (i.e. having a smaller area facing the wind) is relatively weak, while at higher speeds it's more pronounced. That's why you get more distance increase with a driver at higher speeds and less change with a putter, or at least it's part of the reason. I remember that shot on 18 at Waco where you crushed a putter onto the green from like 450. It still blows me away that that's even possible for a human, let alone something you'd do in a tournament.
    8:20 Nose angle, spin, and flutter probably explain at least part of the difference, but there are so many variables that it's going to be impossible to say which ones are important without a ton of testing and/or theory (and probably a wind tunnel). Also, what is the radar actually measuring? "Arm speed" is pretty vague. Which part of the arm? What portion of the throw (beginning or end)? Does the angle you measure from matter? What if the thrower is rounding? There are all kinds of things that could give you measurement errors or misleading data.
    12:15 Spin definitely matters but it's complicated. It will give you more gyroscopic stability if you spin the disc faster, but it will also alter how much it flips or hyzers, and probably affects the flight in other ways, too.
    Anyway, thanks for this nerdy/cool video, it was really interesting. Honestly the most interesting part is how accurate you are at hitting arm speeds. I've seen your old video with you throwing into a net (I think it might have been in your "favorite videos" compilation too) and that was so accurate it seemed fake, or would seem fake for someone who doesn't know who you are. If you actually want to figure out how speed affects distance you're probably best off doing some physics; you're trying to isolate a single variable with a very messy real-world situation with dozens or hundreds of variables, when what you really want is to know some theory. I bet Discmania has at least one good aero engineer who can help you out.

Thats why sometimes it said 35 before reading a higher number - it was reading his arm st the end of the throw and then catching the disc in flight. These radar guns are designed for reading baseball throws so they can read a disc speed no problem.

      Great comment, though I go back and forth on whether Discmania / Innova / Discraft actually employ engineers to design their discs from an aerodynamics perspective.
      Certainly they have disc designers, and certainly an engineer to design the molds, and certainly they will have a manufacturing engineer (or two) go manage the production, but in reality these are probably pretty lean companies. If they were paying $140k a year to someone who was capable of actually evaluating disc flight from first principles, we'd probably have heard about it by now.
      I think disc design remains much more art than science, and that's probably because the industry can't afford to pay for much science.

    I think you're exactly right Simon, spin or rotations has a lot to do with the distance of a disc. There are plenty of other factors as well I think, i.e. disc speed, nose angle (like you mentioned), disc stability, and disc profile. There's the concept of drag which is an opposing force on the leading edge of the disc as it flies (the air pushes against the disc as it flies). I would say that is the main reason for the difference in distance between putters, mids and drivers. Putters have a much flatter side profile or bevel, which provides more surface area which allows the air to slow the disc at a faster rate. I would be curious to see if arm speed is actually a factor or if it is the disc speed itself. I've been thinking about whether I should do some in depth testing of my own on this stuff and this video has lit a fire under me!

    • @docv73
      @docv73 3 роки тому

      I don't think you can answer that. The faster a disc flies, any disc, the more understable it becomes. That's why pros can throw a Destroyer on a hyzer and get it to flip up to flat, or even turn, and very few ams can. Throw a stable disc on a flat release angle at 50 and it flies straight and fades at the end. Throw the same disc at 60 and it turns first, then fades, and flies farther. Throw a stable disc flat at 50 and it flies straight and fades, throw an understable disc flat at 50 and it turns. Throw it at 60 and it turns over and never comes back. All of that generically speaking, of course.
      To compare them you'd have to throw different release angles that would optimize their flight POTENTIAL to see which would fly farther. Throw an understable disc at just enough hyzer to get some distance, then stand up to flat, then turn, then fade back out, and that disc is in the air a long time. Throw the same disc flat and it turns immediately then fades out and isn't in the air a long. Throw it on an anhyzer and it turns over. The first one flies farther. It's not practical to compare stable too understable unless you factor in release angle.

Obviously nose angle is a huge factor. I'm wondering if in this video the speed gun measures the actual arm speed or the disc release speed? Disc release speed is way faster than arm speed if the whip happens. Interesting stuff! Also, faster spin creates more lift on the left side of the disc if it's RHBH throw, so the disc goes straighter longer for sure.

      Its not that they were throwing faster because of the slow run up, it is that their timing was much better leading to better results. That is why pros can add up to 20 mph on a 360 throw. Their timing is that much better that they can actually increase the speed of their run ups and gain speed/distance.

    • @majordude83
      @majordude83 3 роки тому +1

      In that video they also had a speed gun, and the distance and speed were totally correlated. They were generating more arm speed with slower run ups, as well as more distance (and probably also way more accuracy).
      The saying should be something like "slow is smooth, and smooth is fast, and fast is far". "Smooth" basically meaning "well-timed" + "loose" (not overstrained).
      Every musician talks about how "if you wanna play fast, you first have to learn to play slow". You learn the correct technique (which almost always involves loose wrists, shoulders, etc) at very slow tempos (as slow as you need to do it correctly), then speed up gradually. If you try to overs-tension your muscles to squeeze out faster notes, you will hit a wall quickly and likely also learn a bunch of terrible habits that you eventually have to un-learn if you wanna get better.
      Disc golf is the same. If you're trying to change your technique, you have to start slowly. That said, if you wanna learn do huge fast run-ups or 360s, you also have to practice those, but they are very unlikely to help you throw farther if you don't already have solid technique with standstills and slow run-ups.

    Speed is absolutely a factor. You have top-tier rotation, no off-axis torque, and angle / nose control as well.

I did it backwards, but if I were teaching somebody else, I would've wanted to learn that first. It really does go back to just trying to smoothly flat release a putter in a field for me, so much has been built off of that fundamental practice.

    7:15 The two guys' drives at 60mph:
    Rivas' reachback had the disc almost at the height of his left ear.
    Rivas' disc at release point had the outside edge of his disc (the left edge) about an inch above horizontal. (Anhyzer angle).
    Rivas' disc at release point had the front edge about a 1/4 inch above horizontal (nose up relative to ground).
    Rivas' initial elevation angle was negative (below horizontal plane) and seemed to aim to a point on the ground about 30 feet in front of him but quickly bounced up.
    Rivas' disc flight crossed from anhyzer to flat at about 120' downrange. (the only instant this throw was flat; because it was an anhyzer at release).
    Rivas' flight climbed the visual line of trees in the background.
    Simon's reachback was at about the height of his left bicep.
    Simon's disc at release point had the outside edge of his disc (the left edge) about 3/4" below horizontal (Hyzer angle).
    Simon's disc at release point had the front edge about a 1/4 inch above horizontal (nose up compared to ground but NOT nose up compared to flight).
    Simon's initial elevation angle was about 1 foot up for every 15 feet forward ( I think this elevation angle is GREATER than the nose-above-ground angle; so his disc is moving through the air nose-down and causes high-speed turn).
    Simon's disc flight crossed from hyzer to flat at about 85 feet and then from anhyzer to flat at about 250 feet.
    Simon's disc spent more time in the air in a flat state because he crossed the flat threshold twice (thanks to high-speed turn).
    Simon's throw, because the release had a negative angle of attack, never climbs above the visual treeline in the background.
    My conclusion: Even though spin, disc type, and nose angle compared to ground could have been important, the MAIN difference is that Rivas had a positive angle of attack (air hits the bottom of the disc) while Simon had a negative angle of attack (air almost hits the front edge of the disc dead on, but with a tiny bias towards hitting the TOP side more). The resulting effect is that Simon's angle of attack has very little drag, with the added plus of turning the disc to opposite side of where it will eventually fade once air mostly hits the bottom of the disc. Conversely, Rivas's air bounce creates massive drag, and his flight never really has a bias of air hitting more on the topside. (no high-speed turn).

    @rowan1043 3 роки тому +7

    Two things that affect the distance from a throw: 1) initial release velocity, and 2) the initial revolutions per minute (or per second) that have been exerted on said disc.
    Obviously this is assuming the same disc is used, winds are the same, level ground, etc.
    The angle of release obviously affects the measured distance as well, but a particular angle of release for maximum distance to a specific disc will remain the same as long as it adjusts proportionally to the increase in understability throughout the discs usage.
    The things are all determined by the individuals form and the levers they possess and how mechanically efficient they are able to transfer the kinetic energy from their body to the disc itself.
    In my opinion, this is why some players experience larger distances in the beginning of their career when throwing forehand vs. backhand. It is easier to be more mechanically efficient in a forehand than a backhand, and in a forehand one generally produces greater spin (higher rpm's) on a disc contrary to the backhand throw.
    However when throwing backhand a player utilizes much more muscle mass in the throw, and when the muscle mass is utilized efficiently (mechanically) greater distance will be achieved when throwing backhand. This increase in distance is a result in proper utilization of muscle mass/body limbs and is a result of proper disc golf throwing form.
    Spin on a disc gives the disc more rotational inertia (orthogonal or perpendicular to the revolution of a disc) and greater rotational inertia is required for a disc that is more overstable.
    More or less, and increase in spin on the disc results in an increase in inertia which results in the disc "dumping" later in the flight.
    The question everyone should ask to throw farther is this: "How can I be more mechanically efficient to transfer more of my body's energy into the disc?"
    Simon does this exceptionally well (he has a little more experience throwing than most) and is more mechanically efficient.
    Better form = increase in mechanical efficiency = better transfer of energy to the disc.
    To be clear, better form = better timing and everything that form comprises.
    Please feel free to question my comment here, it is beneficial to be skeptical and create scenarios in which the information may be inaccurate (though I don't believe it is) it will help us all to better understand the physics of disc flight.

      Firstly, if you could please tell me the title of the video, I would love to give it a watch, I love his videos and have seen most of them.
      Additionally, short answer is that it is likely Danny and I would agree on this topic, and my comment was not a thorough enough of an explanation.
      Essentially how I view this (and am fairly confident on this however I could be mistaken) is disc golf form acts more or less like a coefficient to the players transfer of energy to the disc. I am unsure how familiar you might be with the idea of a mathematical coefficient (or physics, etc.).
      Let's take Simon Lizotte for instance: He is able to throw far on backhand because he has great form and a lot of practice throwing.
      I on the other hand lack an immense amount of his experience throwing and therefore cannot throw very far (i.e. my form still sucks but I like to think it is improving) and for reference, I am about 6'5" and have a very similar body type to Thomas Gilbert, or maybe Ricky Wysocki.
      The only difference between Simon Lizotte (not necessarily true but for simplicity's sake) is how mechanically efficient we are in transferring energy to the disc we happen to be throwing.
      If I generate 100 units of throwing energy and so does Simon, then it must be that Simon can destroy my distance because I do not have as good of form as he does and thus cannot throw as far.
      Let's say that Simon is about 80% mechanically efficient and I am about 45% - 50% mechanically efficient (on backhand).
      This means that (because we both produce 100 units of throwing energy) and Simon has 80% efficiency while I have 47.5% efficiency, we get this: 100 x 0.475 = 47.5 distance units and Simon will have 100 x 0.8 = 80 distance units.
      The key is that second number (0.475 and 0.8), THAT is the coefficient which is disc golf form (again on backhand in this example).
      HOWEVER, as stated previously, beginners or average Joes SEEM to be more mechanically efficient initially when throwing a forehand, and thus their distance might be greater when throwing than when throwing backhand.
      This is because it is easier to be more efficient on forehand than backhand (generally speaking), but this slowly goes away with experience and players will likely be able to throw farther after some time when throwing backhand.
      Basically, from what you said, I am sure Danny is right, but the secret is how efficient everyone is when throwing.
      A backhand will generate more spin, but ONLY if the person is EFFICIENT, and much more often than not, people cannot throw efficiently which is why they are left wanting to throw farther (and begin to work on throwing form).
      Hopefully that makes some level of sense to at least someone, but that is what I believe to be true. Ask away any other questions or contrary thoughts!

      During a standard backhand you naturally rotate your grip ~180° during the release. And it happens quickly just by holding on to the the disc
      Forehand requires more effort and flexibilty to cock the wrist back 90° plus good timing to get the snap.

  • @seabas22
    @seabas22 3 роки тому +1

    I wouldn't be surprised if Simon had less spin, I think spin has very little to do with the difference in flight. Erin Hemmings test results with accelerometer showed that his throws had lower spin ratio than his friend who doesn't throw that far. Paraphrasing Avery Jenkins - "There's a difference between trying to spin a disc, and throwing a disc far."
    The flight difference was mainly due to trajectory and nose angle, and form goes along with the territory. Nose up air bounce creates massive drag slowing the disc down much quicker and going nose up reduces the glide phase on the way down as it stalls and fades out instead of penetrating forward longer. In order to throw the nose up air bounce you have to throw the disc with a downward trajectory. Simon is throwing with a slightly upward trajectory and the nose down to keep penetrating forward and gliding out on the way down instead of stalling and fading out. Note how Simon's arm and shoulder follows thru upward and the other guy arm and shoulder goes downward coming over top the front leg.

  • @yrrahyrrah
    @yrrahyrrah 3 роки тому

    Spin for sure adds distance due to gyroscopic stabilization. It will counter the flip at high speeds and also the fade at low speeds. A later fading disc will obviously fly straight further. This effect can be seen when comparing backhand and forehand throws for most players, as it’s harder to get as much spin with a forehand throw. The disc flips more and fades earlier.

  • @justinpk422

    This is a fantastic start to the scientific method. We need this to be taken up like 4 notches in order to get some accurate analyses. Throw the same discs indoors at different temperatures and humidity levels. Throw 10 of the same discs all brand new, all the same speed, then again at another speed…etc. repeat with various disc types, and with different throwers. Repeat with different release angles…etc. repeat with different grips…etc. also, record using multiple radars and cameras, at multiple viewing angles and with multiple high speed cameras to cover the throw and the disc, this would allow us to measure the disc RPMs at the beginning, middle and end of flight. I feel like you could get someone like the hack smith, or myth busters to do this. Start a go fund me, I’ll donate some cash to get this experiment done to completion, heck I’ll donate some time and help organize and coordinate the whole thing, just to help get this done in the off season!

  • @flipflat4814
    @flipflat4814 3 роки тому +1

    Higher spin rates will allow the disc not to fade out as soon as it would with a lower spin rate at the same speed, causing a full flight more time aloft which equals more distance.
    Also the angle of attack plays a huge role also, nose up causing more drag and less overall distance.

    • @CMole1
      @CMole1 3 роки тому +1

      Exactly! Higher spin rate -> longer time before fade so disc speed translates to forward travel. Not to mention the fact that once the disc starts turning, it is no longer at the optimal angles relative to forward direction (resulting in more aerodynamic drag).
      Physics! Fluid dynamics interacting with solid bodies, to be precise.

    Wow! I really enjoyed this video🤩 Super interesting & very impressive. I definitely noticed on the distance driver comparison that you threw it flat with not much flight variation, while the other guy threw his nose up, air bounced it on an anny & got a shorter “s” flight. Nose angle & acceleration seem to be big factors in distance. Acceleration from the pocket to release is probably the key factor in spin so that also makes sense. Form is interesting too. I just started to implement an “x-step” after playing for 14yrs😬 I have always done a one step drive off the tee & a standstill anywhere in the field. After throwing like that for just 3 rounds, I added consistently 60ft to my drive off the tee! Keep these informative & experimental videos coming🥏⛓💥

    @andreasericsson6989 Рік тому

    Difference in distance drives with same armspeed is almost certainly down to release (hyzer/anhyzer) or nose angle (nose up, nose down). Given sufficient spin to avoid the disc wobbling at least. Spin can help carry the disc a liiittle bit further after it has started falling, but not a whole lot. Spin also increases almost linearly with releaes velocity, so it's unlikely that the spin rates are wildly different if you're throwing the discs equally fast.
    Nose up will be similar to deploying flaps on an airplane wing, essentially trading forward speed for lift, but if the disc starts wanting to travel upwards, the shear force of gravity will increase. And it's "shear force", not "sheer force". Shear force is what makes it harder to push things uphill even though gravity remains constant. At a 30% upwards shot, you get exactly half of gravity directly counteracting the velocity of the disc, so it will decelerate by 4.9m/s (or 16ft/s). Quite substantial, and wholly the reason why it's so damn hard to throw far uphill. A nose up shot will also cause the disc to hyzer out earlier, because the center of pressure will be much farther forward on the disc. This also happens when throwing uphill btw, so discs appear more overstable when throwing upwards.
    Nose down will produce a more understable flight because more air flows over the top of the disc (read up on Bernouli's principle and the Coandâ effect to figure out why this matters for flippiness), but also less drag, because the bevel of the disc will not be striking directly into the wind. Nose down shots will always go further than nose up shots, assuming same release velocity and hyzer/anhyzer angle.
    For maximum distance, the nose angle must be close to flat or nose down. Anything else will increase drag and reduce distance on the type of bevelled-edge discs we're using today. More beginner-friendly discs tend to have less sharply angled bevels, so will be less affected by being thrown nose-up. Spin, so long as it's sufficient, is *almost* irrelevant for distance. There's some evidence that a "swirling vortex" effect can affect the glide of discs, but insofar as I understand it, that effect isn't heavily influenced by spinrate and the effect of it is barely a rounding error compared to the glide produced by airflow over the disc.

  • @matthewventurini9177
    @matthewventurini9177 3 роки тому

    I will try my best to explain what I think is going on. And I will try to keep it short....ish.
    1. Distance driver throws:
    -I do think you were right Simon assuming the spin is why the discs flew differently
    -I also think that the measurements of you and your counterpart matter tremendously as well. If you have a longer forearm, while he has a shorter forearm, and they are traveling at the same arm speed the longer forearm will transfer more torque (snap) into the disc. Still related to spin but for different reasons other than just form.
    2. Difference in Putter and Midrange
    -Overall shape of the disc. Speed or rim width, a putter has more of a flat edge going through the air, thus requiring much more power to overcome the wind resistance. That's why there was a "hard limit" on the putter thrown at a high speed. While the midrange has a more aerodynamic shape to it and can take advantage of the extra speed put into it, and thus go further.
    -Glide(lift) was never mentioned in your video and I think it always a very overlooked category in disc selection. The reason the putter and Midrange we're so close in flight at low speeds is glide. Putters have a high glide "traditionally" so when thrown at a low speed they can take advantage of all the air underneath them. Now I mention this because it is noticed when you start to increase the speed of the putter. There is very little benefit to distance, because you have started to reach the fine line of wind resistance due to speed (shape) counteracting the glide (lift) to keep the disc aloft. The midrange has less glide (lift), but when thrown fast the wind resistance force is smaller in comparison to the putter and can stay aloft for a longer period of time.
    *There are more factors in each category, but for the sake of length I have left them out. This is what I believe are the biggest points in the senarios.*

  • @jamamassa
    @jamamassa 3 роки тому

    Great video! Adding graphs will help visualize your experimental numbers. As for flight affecting factors. Exit velocity with direction. Nose angle is important to help understand lift and drag. angular velocity (spin) adds angular momentum and gyroscopic stability which can help understand how the disc will gyroscopically precess about an axis. Not exactly sure which axis, it may be related to gravitational axis, lift vector on the disc and the discs rotational axis. off axis torque may cause slight wobbles with these higher speed drives which may cause the disc to lift less efficiently as it moves through the air.

  • @crittercrusher97

    Try a slow mo shot of the angle thrown and the speed of each shot and compare the distances. I think nose angle and hyzer angle will show you some good info. Also is there any devises you can tape to a disc to measure angular velocity or spin rate. May need to look into that.

  • @Spud1984

    I really belive that the revolutions of the disc and trajecory/nose angle are the key differences here. "Perfect form" is what it takes. Every part of the chain reaction plays a big part in getting the next link where it needs to be to get the next link where IT needs to be etc...

  • @DiscgliderPete
    @DiscgliderPete 3 роки тому +1

    Nose angle matters so much, spin rate matters also, but if the nose angle is up, the amount of drag goes out the roof. Drag slows the discs down super fast, It also slows the spin. Spin rate will be higher, the faster the throwers arm/ hand speed, The two work in tandem, or one is connected to the function of the other. My throws at 60mph tend to have a spin rate of 1025rmp’s.
    Backhands throws spin faster than forehands, which is why forehands shots act more stable and fly shorter.….higher spin rate equals more flip. However understanding a disc flipping has a lot to do with gyroscopic procession. With Rhbh, more spin=the disc processes toward the clockwise direction or flips….as the disc slows-spin slows the disc returns/processes toward stability/counter-clockwise.
    One noticeable difference seen between drivers and putters is this, If nose angle is correct, the driver will tend to retain its spin longer than a putter due to the driver having a sharp edge and thus less drag, whereas a putter has a blunt nose, and thus naturally has more drag. Drag is a distance throwers enemy, but is a control shooters friend.

    If the raw speed is the same, it all comes down to nose angle, hyzer/anhyzer angle, rotational speed, direction of throw and the angle of the throw itself (high or low). And of course if off axis torque is applied at the release. The form itself doesnt necessarily have to do anything with it, but the form is delivering the results from the actual contributing factors

    Hey Simon I know this has been 2 years ago so you probably already found your answer. The answer to your question is Torque vs Muscle. Your hips are creating more Spin Torque while your release is nose down with A smooth follow through. More spin= more distance with matching traveling speed. Raivis is using less hip torque & more of his upper body strength muscling the disc not creating as much spin on the disc as you are creating still reaching the release speed, also he is releasing the disc earlier than you are. His flow is not as smooth as yours he's more tensed up. his nose angle is Released slightly up with a little air bounce release killing his distance. he start high on his back reach comes down then up killing his distance on his putter release was A better Reach back point than his previous throw. Theres also the other factors at play hip weighr shifting rear foot ground pushoff while spining hips creating more torque with sling shot release & so on you get the point. Better Form = More Distance. Move like A ballet dancer & not A line backer. Breathing like yoga, Relaxing with flexibility is the key to all Sports & Musical instruments. So if anyone needs to learn something practice & Stretch for muscle relaxation & Flexibility. Think rubber band, it flexes smoothly & returns to its original relaxed state position.

  • @anthonymerriam2046
    @anthonymerriam2046 3 роки тому

    The disc is a wing so it has initial velocity as well as lift, gravity, and drag forces. Additionally, the disc is spinning so it has angular momentum/gyroscopic stability and gyroscopic precession (turn/fade) due to the moment produced by the center of gravity and center of lift pressure being eccentric. The shape of the wing relative to it’s trajectory is dependent on the angle of attack and will impact lift and drag. The changes to lift forces in turn impacts precession. The greatest distance maximizes time aloft and speed. As the disc rolls/precesses the lift vector is no longer parallel to gravity and the disc will fall faster. The greater the spin rate of the disc the greater the angular momentum and the greater the resistance to changing the plane of rotation keeping the disc more parallel to its original trajectory and roll angle through its flight and thus gaining more distance.

    @dickiebrewer1232 2 роки тому

    Simple matter of wind resistance and the approach to terminal velocity for each shape. At some point, each disc will no go any "farther" (not further) no matter how fast you throw it. Faster spinning discs have a higher "precession", which is the ability to stay in the same plane of rotation. If the disc spins slower, it changes angles (hyzers) and points at the ground, which means it doesn't go as far. It's why getting max D involves a little flip during the flight. It's average flat angle resides longer. If you throw 2 "identical" discs the same speed and same spin rate, the one that flips will go farther. Further, if you throw 2 disc the same speed and angle, the one that spins faster will go farther. And finally, if you throw 2 discs at the same angle and spin rate, the one you throw faster will go farther. Pretty simple physics.
