Physics behind backside 50-50: Why is it hard to lock in SCIENTIFICALLY??

You can view 3D models from here:

This is the first time I make a 3d model that features a flat ledge. Honestly, it took me quite a long time to make one and the script of this video is quite messy.

Anyway, we attempt to break down common problems that we experience while trying backside 50-50 grind in skateboarding using 3d models and physics theories.

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.

Do one of these for tailslides. The physics as to how and why tailslides can be so difficult to do at first is truly amazing.

Back 5050s took me a long time to get, but for some reason they are much easier than frontside to me now….what helped me get it at the end is when I realized the trajectory you travel is similar to how a car merges into traffic onto a highway, like curving into a straight line moving forward. The spot you’re landing on is actually front of you, nose-side, rather than thinking about jumping onto the ledge located behind you.

Man the concept of this channel is something I always wondered about. So cool to see someone, scientifically break a trick down in most effective way. Keep up the great work dude🤯🤙

I feel like the biggest part imo is the backside shifty that has to happen. It's so drastically different from a frontside 5050 in the sense that for a fs 5050, you can stand parallel & close to ledge. With bs, your heels hang off and you have to be further away from lesge so as not to hit them, & jumping backwards is so much harder too. So a good speed & a good backside shift are key, atleast for me

[melm]

so cool, still trying to get more height on my ollies and i think your explanation of the thighs lifting the body and the calves doing the pop a little bit after will really help :)

Happy Friday.
Huge thanks to everyone's support.

This feel true to this and some other tricks where the approach to the obstacle/trick is awkward/uncomfortable by definition, so you don't execute your pop/ollie to the best of your ability/confidence because of it.
For instance, you may probably be able to ollie over/onto the ledge just fine, but because you are trying to approach it to backside 50-50 (more awkward approach than frontside, for instance), then you ollie not as good/high as you can because of that feeling.
I think this video besides pointing out specific corrective actions, it also gives us that general insight/awareness when it comes to the awkward/uncomfortable side of grinds/slides.

On most of your problems you're leaving your back shoulder behind. Alot of backside ledge tricks are in the shoulders.

I was wondering why you uploaded so early today, but it's probably night time in Tokyo now and it's actually 8:3ú and the sun just rose here. Anyway, I'm happy to see you uploading consistently. Your videos really help me understand. For example, I couldn't drive a stick shift car, but once I understood what happened in the car when I'd have to shift, I was able to drive. Same with skating.

Bs 5050s r like my arch enemy. I am super interested in trying this delayed pop concept. I'm gonna try it out today

Those r the sickest parks btw🤩😍!!!!

Update: HOLY SH#$T THIS WORKED 100%!!! I SUCKED AT BACKSIDE 5050 AND THIS JUST CHANGED THE COURSE OF MY LIFE. THANK U SO MUCH!!!!

[tasmoua]

Great video. It's the angle your coming at it thats making it difficult. Come almost parallel to the ledge so you can keep your shoulders squared to help you stay locked on the ledge longer. Once you get it down you'll find backside to be easier than frontside.

[slapuhho]

I'm so glad I found ur channel love it it helps out alot and I've been skating 15 years

[joelhellstrom]

This is an awesome channel! Mixing theoretical and practial physics 😅

[KieranClarkSkates]

This is an amazing video mate, with a completely unique view. Can’t wait to see what trick you explain next.

[TheGoldSide]

BEAST!! love the 3D model keep up the grind you just earned yourself another sub.

[donswanick]

though for me personally the issue with back 50s was the slight backside rotation. ollieing onto a parallel sidewalk backside helped me a lot. also trying them on a pole that's laying on the ground. great way to get used to locking into any ledge/rail trick/combo.

[homealone]

I remember my friend taught me these when I was little and I never forgot them . You want to go at a angle like a inward B's 180 on the coping

[pollenskins]

So helpful bro. This really looks like it will help me to do tricks while rolling. The physics and showing how the muscles are utilized are very key concepts, ones that I haven't seen utilized before 👍

[williambo]

this trick is one of the chillest once you locked them in its a great warm up trick and also easy on the body

[claytonbich]

wow this is an amazing video and I actually learned something! thanks!
