Scientific functions of scoop in Treflips.

- In this video, we will try to analyze the science behind the scoop of treflips.
You can view 3D models from here:
whythetrick.io/how-to/how-to-...
We couldn't define what the scoop is due to technical reasons and needed to rely on someone's experiences.
This time, we are making a difference and try to objectively define what scoops are in treflips using 3D technology.
Please take a moment and try to study this in detail.
I'm trying to eliminate subjectivity from my explanation as much as possible by referring to scientific and physics theories. Please use my 3D models to solve your "why."

Traditionally, skateboarding how-to videos have always been subjective and the majority of explanations are based on speakers' experiences.
To avoid relying on my personal experiences, please fully utilize the 3D models.
All skaters have different questions.
So that you can analyze skateboarding tricks in detail and solve your "whys," those 3D models are made fully interactive.
The 3D models feature these functions below:
- change camera angle
- adjust play speed
- change transparency
- display gridlines, etc.
Aside from that, I try to explain concepts of skateboarding tricks based on facts, calculations, scientific and physics theories. I may make mistakes so please leave a comment if you find anything.

This is awesome!! I really like to see a hardflip tutorial
great call. a hardflip tutorial would be sick
Please do the hardflip tutorial
Me too bro!
You're awesome, I've always tried to understand a technical side of skateboarding and you're providing it, from Brazil
thank you dude,
yeah it's always confusing and I'm really glad I could be of any help. please understand that this is just my way of doing tricks. there must be many more ways.
Thank you so much for these amazing tre flip videos. I landed my first one a couple days ago! I'd also like to add that I'm 44 for this is a huge accomplishment for me. I don't think I could have done it without the great details in your videos. Thanks again.
Great to hear that! Without your effort, this video would’ve been nothing.
I find that when I do the scoop motion, if I also add a lot of -Y to the movement of my foot it helps a lot with the Z axis rotation. The result probably looks like what people call a steezy 360 flip where my foot moves far back from the tail. I find this motion of extending my back leg is actually what causes the Z rotation but also more specifically the motion you describe at 4:49. I had a really hard time figuring out 360 flips until I realized that at this exact moment of doing the scoop, your back leg needs to be FULLY extended. What happens then is that while the board rotates your back leg has a little bit more time for your knee to bend and since it's fully extended your knee will naturally bend on its own to bring it back to the board. What most people are doing is trying to scoop while their knee is still partially bent, and what happens there is that when they scoop and jump their bent knee has a tendency to extend naturally so instead of bending inward and back to the board, they will put their foot on the ground.
Thanks for that explaination. Gonna try it.
This video is amazing!!! I'm a student in physics and engineering and have been skating for over sevral years now and i've always wanted to see someone give a scientific explanation of skateboarding tricks. The process of the board rebounding thanks to the spring energy stored in the bushing and the fact that it is the real cause of the treflip is just brilliant. Thank you for this. Much love from France!!
this channel deserves a lot more subscribers
Your videos are great. I've never seen anyone explain tricks as well as you do. You cover every little detail and the animations really help.
Seriously, you're doing something really special here. If you keep it up, I guarantee this channel will blow up.
More skaters need to see this content!
This is the best trick tip channel but it's also the hardest one to find. I can even do all the tricks that you have covered pretty easily but your trick tips still seem to help me get more control over them
New skater and subscriber here, your channel is a gem, i discovered it today. Good job man!
I’m really liking this channel. Definitely one of a kind for tutorials. Keep up the amazing work and thank you
Your videos are amazing! I’ve been struggling with my tre flips lately, and luckily you popped up on my suggested! I’m feeling more confident to go out and try it again!
Man I’ve never seen such in depth descriptions man , this shit is A1
this is my new favorite channel
i love physics and skateboarding thank you!!! thinking about the dynamics helped me learned how to do pop shoves
great video, made me want to skate so I did, would watch again 10/10
this great dude!!
you did it good!!
This is really helpful please make more of these videos
Perfect instructions!🙏
Glad it was helpful!
freaking brilliant
this is gold
Very nice explanation
Playing touch grind really helps u on getting the concept of flip tricks
So underrated 🔥
Wow, man!! That makes A LOT OF sense! Thank you!!!
Cheers from Russia.
this is so good
I love u man!
thank you!
You are very welcome. Did it help you do anything though?
This is insane
Just had a breakthrough with my shuvits after watching this... thank you.
Great!
That...is...not exactly what this was intended for though :)
Anyway, would you like to see more about shuvits? I'm prioritizing what to release next.
Tre's are a long way off for me :) your description of the foot action unlocked my scoop though.
I also found your kickflip videos interesting even though I don't do them yet. I'd be interested to see your insights on the Ollie but Shuvits would be cool too, especially frontside.
Right away sir.
Frontside shove-its would be awesome. Fs is so much harder than bs.
@@Corn0nTheCobb FS shove-its are way harder, for sure. While learning them, something that helped me, is to use your body more like a FS ollie, but halting the body spin after the scoop. This is probably not the best technique for an advanced skater, but this got me crazy consistency with this trick.
This is a question that I'm pouring over in my mind-- it seems like your hypothesis is sound-- that it's the, "pushing through the board not, "out"" that creates that motion of the the flip-- but there's another consideration; it seems like a big part of why, "pros do Tres and not Varials so much" is actually to do with the intermediate axis theorem-- given a perfect, "scoop" that the board is, "360 flipping" because of this effect and the effect of the foot is actually just a, "guide" in the same sense that the front foot is just, "guiding" the board through its, "natural rotation" in space given normal circumstances. -- just food for thought. Your videos are first rate! Cheers.
It's the part of me that actually, "does" 360 flips that, "feels" like your hypothesis is right-- It's really hard to get a decent 360 flip without the scoop. I think there may be examples of 360 flips that are popped more like ollies and kickflips but almost every single trick tip pro-am alike recommends, "the scoop." It seems like it must be a combination of both.
One idea I'm playing around with is the idea that a skateboard with, "heavy trucks" is actually not, "rotationally symmetrical" like an iPhone is; instead of conceiving of a board having 3 with 1 unstable axis of rotation that the skateboard is (pick your poison) more like a Deck (3 moments of inertia) + 2 trucks acting as coalescent momentors of inertia; TL;DR I think this why both Impossibles and 360 Flips are, "unstable" tricks-- aside from what happens during a kickflip that without, "tweaking" the board's rotation with your feet and/or hips that the skateboard doesn't have any natural stable rotational axis. This simultaneously would prove that every conceivable trick (in the Rodney Mullen sense) is physically feasible (since every trick is a, "hack") and that, "the trick" (ie. kicking into the nose for kickflips, scooping the board for 360 flips, scooping, "through" the board without ollie'ing for Impossibles) for all flip tricks is, "how you flip the trick with your body" and not necessarily, "hacking the board to assume ideal conditions for semi-stable axial rotation." Which is kind of like saying, "real flip tricks aren't pressure flips-- they're, "skill-control" flips when you really know what's going on.
The other, "pick one's poison" is to consider that each truck, "contains" (I'm not a physicist!) its, "own" 3 points of inertia which leaves 9 idealized moments of inertia. My assumption is that under these conditions that ideal rotation is the classical sense is exceptional and that given the interactions of all these bodies of mass that in a similar manner to the 3-body problem-- that the interaction-summing-and-cancelling out of rotational points of inertia (in the Calculus-limits sense) through iteration produces chaotic behavior unless stabilized intentionally from some counteracting mass and this is what anticipates the inability for the skateboard to achieve axial rotational stability. It doesn't spin like an IPhone-- it spins like a satellite with long antennas; if the antennas aren't placed correctly it causes the satellite to flip over. The skateboarders feet and hips are the, "dynamic linearizing" force potentials which, "linearize" what would otherwise be semi-periodic behavior.
We need zero G experiments with skateboards. Notice I use the word, "need!"
Awesome stuff - but I keep wondering about a skater such as Daewon Song. He skates without and bushings in his trucks (meaning they flop around the kingpin freely) - does that mean that he would have to apply the kickflip rotation with his front foot?
thanks for the comment.
his front trucks doesn't have bushings but it seems his rear truck does.
ruclips.net/video/pt--3DX-md0/видео.html
do any other tricks involve bending the hanger to build energy in the trucks?
I like the "Conslusion" LOL Actually this channel is really interesting and it seems to be right on
Thanks a lot!
Ive seen the comments here about bushing tightness, and thanks for the answers. I'm also wondering if riser pads would make a difference? It would seem that it increases the depth of travel that you can bend that hangar, so perhaps more rebounding force to initiate the flip rotation? Thanks for video, ive never seen anyone explain this theory which makes complete sense!
Riser pads huh. Thanks for the idea. Will see what I can do!
so the kickflip rotation is caused by the bushings snapping back to a neutral position while in the air? never thought of it that way
I believe it is considering my front foot does not even touch my board.
A few things to note though.
- There may be people who actually use their front foot to flick. Mine’s just one way of doing it, not the only way.
- Different boards would behave in different manners.
@@whythetrick do you think it might help to tighten the trucks so that it creates more pressure on the toe side?
I don’t think so.
I ride bones bushings and they are fairly soft.
U can even make it simpler once u get comfortable
Thank you for the comment.
Is it too complicated?
Question: according to your theories, it should be harder to tre if i had hard trucks
sorry if this video has given you a wrong impression but bushings do not have to be soft, UNLESS yours are as hard as stones. what's important instead is that your bushings have enough bounciness. their hardness may vary depending on your preference.
in my case they are relatively loose. i ride bones hardcore bush medium.
I just realize, this park is in Sangenjaya?
Yiiizz
Could u make a video on how to get air on banks
That’s a good one. If I share some key concepts here,
- Timing is key. Wait until the tail reaches the edge of the bank.
- You may crouch down as low as you want but make sure that your body is extended by the time the tail hits the ground.
@@whythetrick thanks sooooo much ! I couldn’t get the figure out the timing for a long time . I always extend up before I get to the bank
2:25
Like it? Anything wrong?
So what about people like myself who use their front foot to flip the board rather relying all on the scoop?
That, I’m afraid, depends on symptoms they have.
@@whythetrick or Jamie foy who does his tre flips in the middle of the tail!?
Actually maybe I should ask could you try a breakdown of someone like Jamie foy who doesn't do his tre flips conventionally (putting back foot in the middle to create more pop)
just dont stop
didnt explain what the z axis is very well.
ah, that's true. please refer to it as "the vertical axis."
