Love the videos dude. Can't tell you how much they help those of us who over-analyze the game and need to know EVERYTHING about it. You really make it simple Kudos
You guys are really awesome. Always looking forward to new videos. Breaking it down so simply and precisley really helps me understand the physics behind the disc design. It's one thing to have a powerful arm (which I don't), but understanding what a disc is designed to do and why is essental for maximizing skill potential. My game drastically improved after finding and watching your videos, thanks and keep em coming!
I've been playing this game since about 1988*... My dad introduced me to the game and honestly, I can't wait to teach my daughter!! These videos are excellent for all players.. Even you pros!! Pay close attention to what's being said in the videos, and as a veteran player of this amazing sport,, I assure you; your game will improve!!!! Thanks for the video guys!! It makes it very easy to explain to my kiddo!! Please keep up the good work and please keep making these excellent videos!!
Subscribed. I've been frustrated at my inability to drive over 250 with a decent tailwind-- at 5200 feet elevation during the heat of day. Now I know which disc to break out in those conditions. Thanks!
This is by far the best disc golf channel. Amazingly polished voiceover and graphics. As Shane said, my game has improved and I've even used some stuff for my beginner ultimate team.
Thanks for the great vid... I'm not that new to the game, but the different variables still give me trouble and I stay confused when shopping for discs. This will be a huge help.
this is a great video and I like that you covered the Tern. I heard it was a good disc for extra glide and bought one at 166g. starting to wish I had gotten a lighter one as I could have taken advantage of the extra glide if it was lighter. great disc overall, floats better than most that I throw!
Good video. One thing I would like explained is what physical properties account for the flight ratings, such as glide. I appreciate the operational explanations, but really want some analysis of what aspects of the disc geometry account for differences in speed, glide, turn and fade. Also, what is the relationship between each property? It seems, for example, that more stable usually means more turn and less fade, but can turn and fade be decoupled somehow?
Wish you guys talk about how lift is created, I still hear a lot of pros talk about how the "air gets underneath the disc and makes is go farther". Perhaps airplane wings and how the create lift would be an easy to understand example.
+@BlakiDisco Click the link in the video's description -- we've set-up a page with links providing additional detail on each of the aerodynamic concepts discussed in the video. Hope that helps!
Everyone says that as a figure of speech but it is slightly inaccurate. What actually happens is when you throw the disc in a manner that lets the wind push it up, essentially "getting under" it by angling the disc so the bottom of the flightplate is slightly exposed to the wind direction. The misconception is that the bottom of the flightplate generates the lift but it is actually the top generating almost all lift while the disc is in flight and not stalling out. Only at the end of the flight when the disc slows down and starts to fade does the bottom generate lift (and a not insignificant amount of drag). Depending on how sharp the disc fades the top of the flightplate may be more or less detached from the airflow and in some extreme discs act as a parachute.
+Cody Bell I think that depends on how far you throw and how far the hole/target is away from you. Also, it depends on the wind conditions. I know I like to throw low glide downhill in windy conditions, both down wind and up wind if the target is downhill. This way I have more predictability in the disc behavior. If I'm throwing uphill I choose to throw discs that have more glide, in tail and headwinds. I throw my lighter discs, unless there is a headwind that creates a risk of unpredictable disc behavior, in which case I will throw less glide because the headwind is strong enough to lift a low glide disc without the risk of it being too much.
Great video. One thing I disagree with, is that the weight of the disc is pulling it down. The weight of the disc has nothing to do with the force of gravity pulling it down. A 20 gram disc and a 175 gram disc will hit the ground at the same exact time if dropped simultaneously. I think lighter discs act more under-stable because the are thrown with a higher velocity and therefor, get more high-speed turn. Also, a 130 gram disc will not have a flight line shifted up vs a 160 gram disc if they are thrown at the same trajectory. I don't think any disc would actually fly "up" if thrown parallel to the ground, unless there is a headwind.
+bouchercm8 Very common thought! Let's use airplanes as an alternate example. Imagine an airplane flying at 200mph. Now make that same airplane out of solid lead and see if it is still generating enough Lift to stay airborne. For the same reason the lead airplane would fall from the sky, heavy discs need more Lift to stay in flight. As you pointed out, the acceleration of gravity is constant for all matter at 9.8m/s^2 regardless of their mass, so any two items in a vacuum will fall at the exact same speed. The total Gravitational Force that Lift must counter, however, does increase with mass.
To be a bit technical, the speed at which somethings fall with is the same for all objects (being the gravity constant). The lift is a force acting on the disc, pulling it up. While you have a force pulling on it to get down (mass*gravity constant). Now if the lift is higher then the force pulling down on the disc, the disc will go up (even if it is going parallel to the ground). To visualize how lift is created, look at this airplane wing. The concept being the same for an disc. upload.wikimedia.org/wikipedia/commons/2/2d/Equal_transit-time_NASA_wrong1.gif
great vid as alway. i am confused though. isnt hot air able to bind more water (which would increse the density of the air?). So should humidity be a factor?
+Lennart Döring Great question! Yes, humidity can be a factor, but what I think you'll find to be REALLY surprising is that humid air actually provides less lift than dry air. Here's a link if you want to read more: www4.hcmut.edu.vn/~huynhqlinh/olympicvl/tailieu/physlink_askexpert/ae652.cfm.htm
+Tony Pantera I would think of these more on a graduated scale. If you play year-round, for example, when the seasons change you may find that you need to increase/decrease Glide to compensate.
So based on your videos, a head wind disc should be more stable with less glide and a tail wind disc should have more glide with less stability. Is that right?
Yes, that's right! We are actually putting together a video that ties together the concepts from several of our different videos (just like you've done here already)
Quick question, do you ever account for the Coriolis effect when your preparing to take a shot? Seems like it would play a big part in a game such as disc golf but I've never heard it mentioned in any videos.
Isn't headwind pushing discs down in most cases? It is maybe due to stability but the video is somewhat misleading in that sense, especially for beginners.
We have a complete video dedicated to Headwinds and Tailwinds that I think will help answer your question. If you still have concerns, email me any time -- we're always happy to help!
Airplanes take off into a headwind because it creates greater air-speed and more lift. My Dad was a pilot and was an airplane mechanic as well (and talked about airfoils of wings frequently). A headwind will lift a disc unless you are throwing it downhill and the wind strikes the top of the disc more than the bottom. A headwind, increasing a disc's air speed, will cause a disc to turn over more, as if it was thrown harder/faster than you normally throw, so a little heiser release may be in order.
Great video, but I think the people watching these could benefit from a more laymen's terms approach. I understand it's all physics, but making it a tad easier to understand might be beneficial.
I had the opposite experience. I had a lot of people try to explain speed, understable, overstable, flippy, etc. to me and they say things like, "an understable disc will go right." But that is way too simplistic. Just like you can't simply say, "glide means it will stay in the air longer," because that is not technically true. When it comes to these very technical terms and the physical parameters of the discs, a technical approach makes much more sense to me.
