- In this video I explain why fins on rockets, but also surf boards, arrows and airplanes are located on the back of the object, and not in front.

wow, straight to the point. That's nice
Thanks, that's my guiding principle!
This is the best, and only way to make great content man 😁@@KnowArt
Pun intended 🤣😝🤣
@@HhGfg-vq3tp our little comedian 😐
I was thinking the exact same thing. Also he should start a KSP series lol
Best loop ever created
Fr u can’t even tell unless u pause it and look at the red bar thing that tells u how much time u r into the video
If you listen closely the audio cuts so it’s still not _perfect_ but it’s good
Yep
Yes
its decent at best
Dont stop, this is good content
thanks! I won't ;)

btw yes having the fins on the back also creates higher pressure on one side but because the fins are behind the center of mass it pushes it back into place
Thanks. This short is a bit too oversimplified.
That is the point!
Interesting. In which case, how can Starship have its flaps at the top and not send the whole stack spinning around like what happened in flight 1?
I have to imagine the center of mass is way below Superheavy’s grid-fins.
was literally going to make this comment and glad to see that it was pointed out!!! great video simply missed that one key point of center of mass acts as the pivot point!!

1. It also has flaps at the bottom that are bigger.
2. The flaps are really only used to belly flop into the atmo home.
3. Flaps at the top do make it more unstable, it just doesn't matter too much. The lower stage has 33 engines that can steer.
4. Flight 1 spinning didn't have anything to do with aerodynamics and everything to the separation failure. I've never even seen a rocket flip like that and not explode.
5. The grid fins don't do much until the end of the return trip where the direction is reversed. They also steer.
this was the first loop that i didnt realize from the get-go
yess, success!
its a wonderfully clever bit of work
Flip Tha bihh
Agree
I only realised it from the get go because I keep seeing their videos, the loops are so good lmao
NASA engineer: We know
KSP player: We do
Elon musk:
@@viktorbihar5384why is musk relevant... Starship has a lower set of fins
Lol same
I learned this in Kerbal Space Program a decade ago
I’m playing ksp rn 😂
I still play KSP, I love it...
same, well not a decade ago
same lmao
Cool
God those sound effects are heavenly
sounds like a slide-whistle harmonica typa deal
Aerodynamics summarized so fast. I love it.
@@ss84jdtybwit’s still aerodynamics, pretty much everything can be broken down into ‘forces and stuff’, there’s no need to be so pretentious
@@ss84jdtybw you're a disgrace to society.
Yeah I forgot the dude... Uhh Pascal?
Edit: Nvm it's Bernoulli's
Bernoulli doesn't apply here as it is not a closed system. Also it is not the higher pressure created but the lift (with lower pressure) effective on the other side. Explanation not false but also not very elegant.
Brilliant straightforward short video.people are used to long,unnecessary video shorts that they unconsciously replayed it multiple times .
The perfect transition

Not many can pull that off under such a tremendous amount of pressure to turn around.

ironic because this isn't a loop

The aero force is created with any angle of attack, but it matters whether you are ahead or behind the center of gravity
*rocket turns all the way around*
Ah yes, my average Kerbal space program rocket
Solution: add more -fins- boosters.

loop is clean asf ngl
i love the goofy sound effects. they sound like what you would hear when a cat stretches
Satisfying loop, quick knowledge, and… rockets. I like.
Same
Is it "satisfying"tho
@@railfandepotproductions yes
@@tsukiokami1999 so you know of how much brainrot content uses that word
@@railfandepotproductions this isn't brainrot content though is it? its quick, to-the-point, educational videos and the loop tends to make people watch it multiple times cause it is genuinely the cleanest one i've ever seen
Im getting kerbal PTSD flashbacks.
Rest in peace, Jeb, Bob, Earmin, and Jeremiah.

Conclussion: the fins want to go at the bottom
This is in loop...I was watching it for 10 times 😂😂😂
Space X: let me stop u right here
Tell me which type?
Nuh uh
@@arghost9798 Starship
Oh really
I was thinking AIM-9 Sidewinder, though in both cases the stabilizing fins are at the back and the maneuvering fins are up front.
the perfect loop gave it the "crazy? i was crazy once" energy. Also, aerodynamic :D
🐀🐀🐀
the perfect loop, you dont even see the stutter at the end when it loops back to the start. Very well done
Kerbal Space Program players take note
THE ACTUAL PERFECT LOOP, IVE NEVER SEEN IT BEFORE BUT ITS PERFECT
The cut is so clean
I swear its always such a perfectly smooth transition
This design was actually adapted from the ancient arrow (from bow and arrow weapon) which has its fins also in the back.
Sure but in engineering we don't do things just because they did it like that in the past. There's a reason why the arrows had fins that way and there's a reason why rockets are like that too
The rocket at this point is a fat arrow smh
do you know why the fins are on the back of the arrow??
yeah, thats the point of the video
Aerodynamics were not invented by humans
the fins being on the front vs on the back is what's called unstable vs stable equilibrium. technically, if the rocket stayed perfectly vertical the whole time, it could fly with the fins on the front, as it can with the fins in the back. the difference is that, when the fins are in the front, any slight disturbance grows uncontrollably, while, if the fins are in the back, any slight disturbance corrects itself
it's the same as balancing a pendulum at the top vs at the bottom
That is the most perfect loop.
HELP I'VE BEEN STUCK WATCHING THIS FOR A WHOLE HOUR
The sound design is excellent
that's probably one of the BEST loops I've ever seen
Holy this was so good
This guy knows how to loop respect so I subbed
Awesome🎉
The #1 physics demonstration taking all of America by storm right into a deluge of concussions.

Gotta have that vector😎
@@NapoleonBonaparte3 Gotta have dat control authority.
For those interested in the specific terminology, you have to have the center of gravity in front of the aerodynamic center (where the wings are).
This is why darts and arrows have their fins on the back and part of the reason why aircraft have a tail.
Probably one of the cleanest loops I’ve ever seen
No shenanigans, just straight to the point👍
the sound designer is going WILD with those
love them
It's really cool when you ask "why is this built like that?" And the answer is "because it wants to be."
Finally this is a perfect loop
ive been watching for 123454 hours and im going to watch this until it ends i swear
I figured this out as a kid - without the pressure argument, but the concept of a stable vs. unstable equillibrium is pretty straightforward.
And, I bet you always pronounce the sound "th". 😒
Finally straight to the point
Bro the loop is so clean that I didn’t even know it looped until I watched it five times
This is just the best channel right to the point got some laughs and educational
this feels like an entry in the Hitchhiker's Guide to the Galaxy
Man the sfx’s are crazy, the quality of the content is so great, keep it up 🔥
These sound effects make me happy
wow the loop is perfect and so straight of a point
Even without knowledge in physics, fins in the front is hilarious
Now the grid fins on the falcon9 makes so much sense! Keep it up with those awesome contents!
This guy has made the cleanest loop ever
Informative. Best two hour demo ever.
I’ve been having this issue in ksp for months you just fixed every problem I’ve had
I love how this made me understand center of pressure and center of gravity but the textbooks didn’t.
Learned this the hard way in Kerbal Space Program, not really knowing why it happened. Thanks for the knowledge!
this mans transitions are insane
Okay that is one seamless and super clean loop!
If this dude doesn’t get a diamond play button of these vids alone I’m gonna be pissed
I say it again, one of the best channel
This is really cool stuff; you have to have the center of pressure and center of gravity in different places to prevent this, which is why we put payloads at the top of rockets to make them... top-heavy 😂 and fins on the bottom for the reason shown above.
It’s not just about the placement of the fins themselves, but how they move the center of pressure around depending on the placement. The closer to the center of mass it is, the easier it is to turn the rocket, but putting it in front of the center of mass forces it to turn. Rockets don’t need to turn very quickly, so their center of pressure is far behind the center of mass.
Amazing explanation on why throwing darts by holding the tip will always turn right side up
This content is amazing, straight to the point.
Ok this is the first short loop thats actually good.
Do the pendulum rocket fallacy next! I love that one!
“Creating higher pressure”
*AGGRESSIVE CALL OF DUTY ZOMBIE NOISES*
That was the cleanest cut i have ever seen 🤯
man this is hypnotically seamless
Thats a great example of positive feedback.
Genuinely never would’ve asked this question but it is very well produced content so I can’t even be mad
The Rocket and Sound Had me dying 😂
ITS SO CLEAN OMG THIS LOOP IS SO GOOD
We be making explosive altery with these one 🗣️🗣️🗣️
Why did I get 20 rocket shorts in a row? This cannot possibly be a coincidence
why the weird sounds lowkey satisfying?
Now we need an explanation to the fighter jets trying that method for higher pressures. 😂
One of the best loops I’ve seen on a video.
Im eating ham… just slices of ham, while watching this. I have ascended past the normal human, and this will be the peak of my life
I’ve never seen such clean loops
These these loops are crazy
Been watching for 9 hours no end in sight
My guy, that's some fine work right here. Props to you
Brillant loop, not only visually but rethorically, too!😁
That was the best and most quick explanation ever. Love it
Bro this is the best loop video I’ve ever seen
Thanks for helping me with my ksp career mode play through
soon as i saw the channel, i looked for the loop. took me a while tho
Front fins (canards) are actually really good controll surfaces. However, they are inherently unstable and usually require micro-adjustments to keep the fins at the correct angle of attack.
HOW ARE YOU LOOPING THIS GOOD!?
Talk about the failures of pendulum rockets if you haven't already! Probably some of the most eye-opening physics experiments
cleanest loop i've ever seen
