[@Cyberlord_Blaze]

I believe Jarvis is still way ahead what we currently have. Or at least most of what we have. He's incredibly intuitive and performs many functions with ease. It's also impressive how well he can be transferred to other computing systems, just like how he did in the first movie when transferring in a matter of seconds into Tony's suit. The incredible amount of data involved in his AI would need a lot of computing power and storage, plus a transfer of it I imagine would be time consuming. He would be the equivalent of an AI with a giant training model covering just about anything and an extremely complex layered neural net.

[@sirensong6172]

the more access to information the ai has, the smarter it can get. give it access to the entirety of the internet, including government confidential records and ai training, and it will be perfectly stand alone. add in the human "core" and the ai will actually have to hold back and adapt to what the human is capable of, as its primary weakness.

[@dybiosol]

18:06 Distributed thrusters is actually a thing that Tony adds in his Mk-2 suit once he comes back home (probably because of the massive injury he faced after the crash landing of the crude Mk-1 suit). If you nitpick through the first montage of him training to use his new suit, you will see the initial pre-flight caliberation sequence that Jarvis runs during the suit up. Everytime Tony enters his flight mode or uses his palm thrusters for offensive blasts, the distributed thrusters in this back also light up and fire off for counterbalance. These tiny thrusters, accompanied by tiny moveable winglets, from my observation are present near his abdomen, higher back, middle back, thighs and leg calves which help him in his flight balance and save him from momentum impacts.

guys that is why its call a MOVIE. and a great one too... just sit back and enjoy it dhaaa.

[@MonkeyDLuffy-cm4fm]

Just to clarify one thing. When Tony explained his reactor’s power it was the first one and in the movie he upgrades it and the bad guy stole the upgraded one and he had to use the old one that he made in the cave and the A.I said that one is not designed to fly. Also the tank hitting Tony it doesn’t show it was direct most likely it just grazed him and sent him off balance. Thanks for the math you doing amazing video by the way I love it.

[@SimonBenjamin]

Yep true we don’t know whether the tank shell was direct or glancing. However if you watch the scene the impact does dramatically change the way Tony is moving, so there is a big change in momentum, and his body would have to pay the price for that. And yep the power reactor gets better over the movie (and over following movies) I guess I’m saying that even the first one has plenty of power to make the things we see possible (from and energy point of view at least).

[@oddcool1]

​@@SimonBenjamin I would love a updated video on the suit. Since the tech he's using in the suit can be something like graphene or carbon nano tubes or artificial muscles that is either dampening the force that the armor pieces on he's suit experiences and counter reacts that down to the level that makes it equal to the damage he took as seen when he's home and out of the suit. And the suit has a pressurized internal area for him and he's body too. And the shell he got hit by can also just be a AA shell/shrapnel shell or a HE shell, since it's Shooting at a flying target witch would mean any sabo or anti armor rounds would be most likely not used for something like that at those ranges (1-2km by a estimation of the distance shown in the movie) and since he lands or crashes some hundred meters away from the tank it's self maybe as much as 500m but more likely around 100-200m out. The arc reactor on the other hand can be a more advanced version of the prototype large plasma/fusion reactors we are currently testing and building here in europe. And last but not least....he's weight....200kg is not that much for something that advanced....so i'd increase it to at least 400kg maybe even 500kg.

Momentum conservation makes a perfect case for the infeasibility of such a suit today, at least one that can carry a human inside of it.

I know this is four years old but seriously….I wish I had a teacher like you to help explain me abstract concepts like this.

If you I could have had someone like you teach me using comic books and movies….I have been such a better student. Good job dude and thank you for doing this. Also to kind of bring a bit of nerdiness into this: the movie does depict several additional thruster through out the suit for flight stabilization. If you review the scenes when he is developing flight in the suit you can see these several tiny thrusters in the exposed boot as he successfully lifts off. I do not know if they are enough thrusters or anything like that for what you said. But i believe we are left to assume there are several flight stabilizing thruster through out the suit. One could assume that power could be routed to those thrusters in a big way via automation in the form of the algorithms in the Jarvis AI. I dunno if I am on the right track or reaching.

[@superpaytonmars8852]

One possible explanation could be drawn from the comics. One of the armor's standard features is an EM force field. This is most likely what protects Tony from impact trauma, his suit generates an energy shield that reinforces its already impressive durability, while also protecting him from massive impacts that should liquefy him through sheer force. This would also explain why Rhodey was so badly injured from the type of fall that he and Tony have both most likely survived dozens of times over, his power source was destroyed, and his EM field with it.

[@sublimechimp]

Love the explanation of conservation of momentum. I’ve seen other films overlook this fact as well. Bulletproof, even missile proof, doesn’t mean momentum proof!

[@ggt5997]

cold fusion is what its more similar to just that no major strides have been done with it in decades.

[@eduarddvorecky3731]

12:10 It depends on what kind of projectile hits him and if it's hit as you have assumed wich is basicly worst case scenario or if it's glancing hit (bounce) wich can be anywhere from deadly to survivable. From the short clip shown in movie my best guess for shell type is some kind of HEAT shell wich uses explosives in the shell to get trough armor.

I cant stop thinking about this theory lately but i need a professional to guide me, i hope i will be as smart as you and you responded to this thoughts, thank you professor.

[@SimonBenjamin]

Hi, thanks for the comment. Well what you are describing is similar to the way regular jets work (which heat up air to make it expand and push it out the back) or drone engines (which are just fans to push the air) so it would definitely be possible according to physics! The challenge is to have a light and powerful source of energy to make it all work. The recent progress in drones is partly because of better batteries, but you'd need something even better to lift a human and keep them flying for a reasonable time.

[@kevinwestrom4775]

Great video, I really loved it. In the comics at least, Tony had come up with a neat way to bypass the problems of acceleration of the suit on the human body internally of flight forces g's, and also externally from incoming objects, i.e the tank shell, or whatever else, via his Tony Stark patented "inertial dampening field" (exactly like you mentioned for the STTNG). So that IDF would minimize or cancel out incoming tank shells, suddenly massive momentum acceleration/deceleration launching into flight/landing or slamming into the ground as he did. Tony Stark as a mega-super genius did come up with the inertial dampening field, his mini-ARC reactor, his very intelligent general AI JARVIS,, and even more. I would think the one thing that he couldn't do, would be to create a near 100% efficient power reactor to generate 3 GJ/s / 3 MW of power from something that tiny, Without it creating either a huge amount of heat or radiation as well as by-products of its power generation, so cooking him inside the suit by that alone, or irradiating his body in the course of the power generation. Tony did come up with a Structural Integrity Field (SIF) to reinforce his armor from penetrating hits from incoming high-velocity rounds, armor-piercing around, etc. and thereby making his armor pretty much nigh-impregnable except by extremely powerful impact forces to over-power the suit defenses, and magic of course.

[@SimonBenjamin]

Ah that’s interesting, I’m glad that the writers thought about the problem and made it so that Tony has solved it. I think it’s really, really hard to solve though - probably a problem for hundreds of years in the future, rather than a really smart guy in the current era. For a power source that doesn’t get hot... that’s more of a huge engineering challenge than a problem with basic physics. In principle you can add a heat pump (powered by a fraction of the reactor’s output) that takes waste heat to anywhere you want it e.g. the flight boosters. Mind you, practically all today’s power systems DO use ‘thermal reservoirs’ to just dump heat, and Tony can’t do that, so a lot of the innovation in the suit would need to go into this issue.

May I Propose that the suit could have a gel layer to help absorb the impact and distribute it thru the suit? almost like what they would use in the Halo Franchise a Hydrostatic Gel Layer which is a semi-liquid substance conforming to the wearers body regulating temperature and has an ability to pressurize to help the survive hard impacts and landings not MCU Canon but none the less possible knowing tony's ways of adapting to circumstances possible future ones and past ones

[@ryankozak99]

This "gel layer" (which couldn't be more than 10cm) was more than accounted for when he said the acceleration takes place through the size of his body. The problem discussed isn't distributing the force, it is surviving the acceleration.

[@user-lj4xq4hm3k]

You still run into the issue of your internal organs liquifying inside your body.

[@nutria_official]

In some of the later fiims, Tony also have these thrusters to potentially cancel the momentum

[@victordave2011]

Note: I may be right I may be wrong. I think Tony has this into consideration as well. Further in the movie, when he comes back after killing the terrorists in the village, and pepper walks in and says "are those bullet holes" We are able to see inside of the suite for a moment. There's another piece of armour which is few cm in distance to the actual suite over his spandex suite that he was wearing all the time inside the Titanium alloy suite. So when there was a great impact on the outer suite by shell and then he dropped to ground using your explained physics, the momentum was conserved by the inner armour and not Tony's human body. Cannot say the same about his head though. Let me know if I got it or that would also fail.

[@gilcarvalho7744]

@@gilcarvalho7744 Agree with you. "IMO" the internal armor is like an armor inside the armor to keep Tony safer than normal ( if not totally safe) and save him from getting splat pasted. Like that one stays suspended inside the Titanium alloy in case the outer armor actually rips apart like in Ironman 3. Not to sound too much taken about it (as it actually isn't physically real thing, yet.) but Marvel has showed each added feature clip in first three Iron man and Avengers movie.

One issue with a generator producing 3GW of power right next to (or even in!) a man's chest that you didn't mention is the amount of heat it would be generating. Even if the Arc Reactor itself has perfect 100% efficiency, simply transporting that kind of energy via simple wires, or using it in thrusters, would most definitely produce a significant amount of heat.

[@_uncle_joel_]

I guess using Tony starks nanotechnology the nanomaterials making up his suit cud be propelled with a significant enough acceleration to oppose the launcher. So long as they were propelled at a big enough distance from Tony (but small enough to reassemble on his body) the force cud propel them again back into Tony's suit. Assuming there is sufficient absorbant padding under his suit his body cud survive a blast like that as his body now needs to accelerate less to survive.

[@SimonBenjamin]

Yeah I think that the cool nanotechnology suit in the Infinity Gauntlet movies could potentially solve the problem. Because that thing is so advanced that we can’t say what it can/can’t do - maybe the nano-elements of the suit can produce a counter-force when needed as you say. That’s why I focused on the suits from the first movie since they seem limited to near-future technology

[@esk8er900]

I’m sure it’s been mentioned but we actually see most of Tony’s suits have additional thrusters in the shoulder blade and calf areas. The portrayal of these features varies between movies but it is in fact there. Also I would imagine as the genius defense contractor & weapons designer he is, he would make sure Jarvis is constantly on alert for nearly imperceptible threats to auto engage before Tony could even react or simply without His input. I mean we now have pretty decently self driving cars, albeit with room for improvement, they can parallel park, tell if somethings in their path, stop or attempt to avoid collisions, and maneuver down a highway pretty easily… so it’s probably safe to say tony incorporated micro thrusters akin to those on satellites or large sea vessels to maintain stability or do fine course corrections. Regardless great insights here, I’ve seen this vid a couple times over the years and it’s always a joy!! Thanks dude!

[@randomknight2585]

On his propulsion systems, from what I know tony stark uses muons as his propulsion method and main weapon systems in his palms, would this be possible.

[@SimonBenjamin]

hmm I don't see why not! Muons are made naturally in the upper atmosphere from high energy light striking atoms in the air, so Tony's suit could create them too as long as the suit has enough energy (which it can have plenty of, as I work out in the video). of course he would need to create much more intense muon radiation than the natural level. Muons also penetrate further into matter than (say) x-rays so it might make a dangerous weapon.

[@RabbiB0Y]

judging by the design of the big arc reactor its seems to actually be a Hadron Collider just smaller like the ones that are apparently being made today (more close to the size of the big one that Howard Stark made not smaller ones as in the one Tony made) and there might be a way to shrink it even more than we currently are although the heat would likely burn Tony to a crisp

[@digitalcurrents]

Redirect the heat into a contained quantum black hole.

[@redthunder6183]

10:24 I would like to point out that that number is the total energy consumed over the distance. And that’s a fraction of what the reactor produces in a second. So basically, with these assumptions, the suit could fly 10km in under a second (starting with 0m/s)

[@DrXenolan]

I wanted to check something which went unmentioned - namely, how much heat is Tony producing with his thrusters? When Iron Man goes 10 km straight up, 20 megajoules of his power goes into thrust. However, because his thrusters are only 10% efficient, they consume 200 megajoules to do it That extra 180 megajoules goes at least partly into light and sound, but mostly heat. How much? I did the calculation for titanium, and it's enough heat energy to raise the temperature of 100 kg of titanium by about 2500 degrees Celsius (unless I'm embarrassing myself with bad math). Obviously, that heat would be almost entirely dispersed away from Tony's body; it's not like he points the thrusters towards himself! But that's still a very significant amount of heat coming out of those thrusters, enough so that whatever takes off from or lands on had better not be something he wants to keep. Also, one really can't blame the robot for repeatedly dousing him with a fire extinguisher. However, I think that the manner in which the thrusters are shown on screen indicates that they are actually much more efficient than that. When he blasts things with them, they get thrown across the room; they don't tend to scorch and burn. So, somehow, a much greater percentage of the energy generated by his suit goes into actual thrust rather than heat. The question of how efficient a thruster can be within the laws of physics, I leave to Mr. Benjamin. Thanks for the entertaining and thought-provoking video!

[@NoxAngel94]

Oooooooor his suit should be of vibranium :D

[@SimonBenjamin]

Yeah depending on the movie (or comic) you read, vibranium definitely seems to be able to violate momentum conservation. To a physicist this is may actually be a bigger deal than, say, time travel ;)

[@LegendFF09]

i like your explanation sir.

[@Essutos]

To my knowledge, what would have killed him long before the massive acceleration is the efficiency. Even if we say that efficiency of that power generator is 99,9%, given that it produces 3GJ/s it would bake him in an instant. Not to say that efficiency of units in his suit (jet engines and others) are nowhere near 99,9%

[@manilkasheran2934]

I dont't want the heat loss of 0.1% from 3GJ anywhere near my chest! lol!

[@digitalcurrents]

Suppose the arc reactor is able to create self-contained quantum black holes and waste heat is redirected to these black holes?

[@Essutos]

@@digitalcurrents but what happens to that energy? We know energy cannot be destroyed and black holes evaporates, so they will return exactly the amount of energy they consumed. In a closed system energy must be conserved

[@MrCheckster2000]

Really enjoyed your explanation of the types of forces on the suit. Ive always questioned that to myself.....lol. but job well done.

[@patrickalexis3600]

This video, is to much thinking for the average person.

[@niokeanu]

18:12 so basically we need a high precision/efficient sensor and thruster so that it can act instantaneously when any potential stimulus hits 🎯

[@gabetelevisiononline]

I think many of us already knew, surviving the kind of impacts shown in the movies, is the *unrealistic portion... But this is a great video! Congratulations *Unrealistic meaning it defies the laws of physics not that it goes beyond present technology.

[@jerryj.2346]

Sounds like a concussion. Good point about the suit. He's taken so many hits. Can't wait to watch the movie with physics in mind.

[@doricy.]

This video is gonna blow up, keep up the good work!

[@ErWin1.0]

love the way you transmit you passion to physics. I'd love to assits to your classes, sincerely.

[@sublimechimp]

Love the description of forces as being communicated too

[@legityash]

I wish i had a physics teacher like you.

[@jeevanjosh5379]

Marvel studios might have seen your video.. Iron man got back thrusters in infinity war😂

[@ashember]

Really great explanation!

[@jacksonburger2081]

Bit late, bud to be fair, their universe has actual gods, magic stones, a big, green man who didn't die, and a girl who can travel the multiverse without even knowing how. I think it's fair to say they might have different g forces than us🤷🏼‍♂️ But it's a GREAT video for a similar device created in our universe.

[@vincembbe]

love every bit of this! fantastic

[@passingby7967]

This is the first video I'm watching in your channel, and this video really excites me since I'm looking forward to taking physics class next year in high school! Thank you for making this video so interesting and helpful.

[@vishwabasnayake782]

I think I have to watch this video 5 more times. Great explanation with a light of speed😊

[@ebiven1563]

What if the shell just glanced off him and wasn't a direct hit, or what if the shell exploded on impact

[@ryankozak99]

Comments Correction: Many commenters argue the impact could be absorbed by ballistic gel, vibranium, or some other material to uniformly distribute the force across Tony's body. But this is confusing uniformly distributing loads with the conservation of momentum. At 14:02-15:00, Simon says he generously allows for the hands of god by saying Tony is accelerated over a distance of 1 meter. Tony's body wouldn't have to be broken by the suit - it would liquify itself internally (imagine a centrifuge separating the contents of liquids). Eg: If you were neutrally buoyant in an infinitely strong pool and it was dropped from a height of 1km, you would be perfectly enveloped by the water on impact (and would remain surrounded by water), but you would still be toast. For example, your lungs would be forced up relative to your denser parts being forced down within your body.

[@mtraven23]

really like your approach to analyzing the physics.

[@deep7nshu]

11:33 I guessed it right, the transfer of momentum from the attacker to Tony must fly him away 😂

[@strongerandstrongereveryda4899]

Wow... your explanation was super clear ... I understood everything that you explained and it was interesting.

[@ZezoFleck]

Physics doesn't quite sound like physics, unless it's with a British accent

[@Marisa_arts]

This video is really amazing and useful for a lot of my work for fiction writing :3

[@sakhitiwari5104]

GREAT VIDEO ! I always thought about the momentum thing , finally satisfied with your mathematics too.! thanks !!!

[@Saluchik]

For the shell example, you are assuming that he stops the shell, but, you can see in the video, that it makes him "spin" and therefore the motion deflects some of the impact?

[@jadinhtvt6870]

Please make more videos you're channel is really good

[@SimonBenjamin]

Thanks! I’d like to... anything in particular you’d like to see?

[@KUKRETI07]

ok so here is your second question answer.... look first admit that tony suit is made up of super light and strongest material secondly, if a 5kg missile go through his suit then it pushes THE SUIT from one to another direction because of momentum.. and his suit will absorb all momentum.... so inside today will only travel with it because of the toughness of the suit...

[@smrutiranjanmohapatra5487]

Sir your way of explanation is beautiful enjoyed this video very much I wish if you are my physics professor it would be amazing 🤗

[@pradyumnabilagi7661]

Wow I love this video exactly my thoughts, a gravity like force that acts on every molecule on his body to completely avoid internal forces. That is soo cool

[@AdamFBuchanan]

@14:25 The super hero/ villain pose of triumph and excitement with fists clenched. haha. awesome. "14 zeros... ( The pooower!!! muhahaha!)"

Excellent work, let's build an iron man suit, iron man is my inspiration..

[@rollandyoakum7844]

I really liked this. I'd love to see your hinted at "Physics of Hulk" video, but couldn't find it.

[@robertkesselring]

My understanding of the momentum issue was that the forces are distributed uniformly through his body by diamagnetic repulsion, similar to the levitating frog demo, but scaled up.

[@demon_srt1992]

Awsome physics ...but there is no lyks.... can't understand why....but his explanation is very very fantastic

[@Henry_the_hen]

Bro this video is awesome you did a great job explaining it

[@AndrewKS86]

Glad someone finally mentioned momentum conservation

[@mad_titanthanos]

While i couldn't comprehend some concepts you're a great teacher

[@WelcomeFellow]

Amazing Video, i like your enthusiastic approach it was very enjoyable!
