Before commenting about acceleration, please watch the video linked at the bottom of the short, entitled "How Far Do You REALLY Fall in Portal 2?" Almost certainly, whatever you have to comment has already been commented 10,000 times and is also entirely incorrect. Original response: Well this certainly exploded. I really appreciate all of the positive feedback/support this video has gotten, it really means a lot to me and makes me super motivated to make more stuff. That's probably a really bad mindset to get into long term, but for now, it really feels nice and I am super thankful for everyone who has lent to that (mostly the wild TH-cam algorithm lol) That said, I've been getting a lot of comments critiquing the methods used in this video, so I wanted to clear it up further: There is no "right" answer to this question. Any different way of looking at this problem will yield a completely different answer, and the designers never intended for this level of scrutiny in relation to real life physics. That said, I think you can determine, with reasonable certainty, a rough estimate of how far you were *supposed* to fall in this section of the game, simply because of the signs located on the elevator shaft wall, which is where some seem to have missed the point. As this is a fictional game, everything bends to what we are given in game, including the laws of physics. Using air resistance/terminal velocity, acceleration, etc entirely misses the point, and instead serves to answer "how far would you fall in real life if you fell for as long as Chell does?" not how far you *actually* fall in the game. We all accept the unreality of portals in this universe, there is no reason to not accept that gravity or other physics work differently here. The little math I did in the second half of the video uses these signs as a model for the players speed, deliberately ignoring all other physics to create an answer that is truthful to the ""lore"" of the game. Also, while it is true that I ignored the small part of the fall at the end, including the "last" sign (which is hidden behind a pipe) the amount of time you fall here is ultimately negligible considering the amount of rounding I did near the end. The extra distance is 125 meters, which when added to the rest of the fall, creates a final answer of 2,093 meters (effectively the same thing). Finally, a little piece of information I discovered while making this: The sign textures go up to 5,250 meters, far above the point we see in game. Maybe the fall was supposed to be longer, but was cut down before release?
That would be farther than the center of the Earth. Gravity would be almost nothing at the bottom and they would have been falling at Mach 1500 by these calculations.
The fact that the Aperture facility is so massive that it extends at least 2 kilometers deep is just terrifying, but let's be real its probably alot more since we were already pretty deep in the facility when we start falling
So if you add the start, before she wakes up again, plus the 2 kilometers in the video, and then the extra bit at the end when she gets knocked out, damn. She fell farther than 2 kilometers by a good margin.
Not to mention Wheatley even says it extends down for "miles". 2km is only about 1.2 miles, so if he's actually right about that, it'd definitely be a lot more
You can, but is it fun tho? Remember, some people like math, so they do the complicated calculus for fun, they can do the sad quick way, but it's not fun
seeing this game re-enter the internet stratosphere (no pun intended) makes me so happy. i love the idea of those who were just outside of the demographic when the game launched getting to experience it, and throwing themselves as deep into the lore as i did
I was really young when it first came out, and I only recently played the portal and half life franchises. They were so good and the lore in both was so interesting. After completing portal 2 for the 5th time, Its definitely my favourite game.
I like how you say "if you paid attention to highschool physics" when you completely forget to account for the acceleration of a falling object (9.8 m/s²)
@@nikims_ in game you don't accelerate so there is probably some weird device in the tube that caps your velocity, cause at aperture we like to throw science at the wall to see what sticks
@@nikims_ take terminal velocity into account, for the first 12 second you would be accelerating at 9.81m/s^2 minus air resistance. After that the rest of the fall is at a constant velocity. The first 12 seconds is 5% of the fall time and to annoying people like me that is important
IIRC is only about 30m to reach terminal velocity. Given her orientation is vertical her terminal velocity (without doing the math) should be somewhere around 150kph. If there was ANY realism she's dead in any landing scenario.
All really cool with the math and stuff, but if you do “cl_showpos 1” in console you’ll notice you have a velocity of 0. And the map is just moving up and you’re stationary. So really you don’t fall.
Oh my god I have been obsessed with portal 2 for like 5 years now, I just can’t get enough of it and before you ask yes I have also played the original both are amazing its just portal 2 is 👌🏽
I wrestled for years with the question of which is better between 1 and 2, and finally I came to the conclusion that Cave Johnson isn't in Portal 1, so Portal 2 takes the cake
“If you paid attention in high school physics then you would know” that not only is gravity a thing that exists, but so is the acceleration it induces.
sure but that doesn't apply to most video games and especially the source engine, you pretty much hit terminal velocity after like half a second of falling. but thank you for expressing your knowledge on the subject
@@orbglorb-zingalorg if youd like to use the “its a videogame” excuse then you probably already know that gravity would be 11.43 m/s opposed to our 9.8, so with your ‘negligible’ time before terminal velocity the fall would still be off by over 375 meters. but thank you for expressing your knowledge on the subject.
you would actually need to figure out what chell's terminal velocity is, then calculate the time to reach said terminal velocity, calculate the distance traveled in that time and then calculate the distance traveled in the rest of the time
Well when you are falling you are accelerating only at the start then you reach certain velocity where air actually slow you down more that gravity pull you so you are going with the constant speed
Terminal velocity isn't really a serious topic here as it only applies because of friction from the air rubbing against you; something I doubt the devs put time into simulating lol. More likely they just chose a non-disorienting steady velocity to fall for - far less than terminal velocity for an upright human. At the end of the day, eh. It's a video game being a video game I can suspend my disbelief
@@Encorous While the devs didn't sinulate the air friction, they do put a final velocity, that's your terminal velocity here. (You don't accelerate infinitely.)
@@SantiagoAbud "Terminal velocity" is a specific term referring to the force of friction exerted by particles in a fluid on a free falling object that opposes the direction of motion. At a certain point, the frictional force becomes equal and opposite to the force of gravity, resulting in zero net acceleration. This scenario, however, is an example of just an arbitrary in-game velocity. From a technical standpoint, none of this involves terminal velocity. It's one of those terms that is a special case, and isn't used to simply mean "a velocity that is terminal". Like "displacement" vs "position": same premise, different application.
Free falling means accelerarion so you just found the average speed when you divided ny four. You cant use that average speed for the rest of the fall. You need to find the gravity by 125=1/2*g*t² then you can find the displacement
Gravity is a force, so the fall rate increases as a function of time. Also at a certain speed you stop accelerating, so those numbers you calculated have to be off as fall speed isnt a constant
While Juan Max is using terminal velocity wrong, game is game. From the point of view of the player, you certainly aren't accelerating while you fall. The devs probably chose a non-disorienting speed to simulate falling at and called it a day. Terminal velocity only applies when air is a factor lmao. Individual-air-molecule simulation in a video game, from what I hear, is a littttttle hard to pull off lmao But hey. At least you're prepared if you fall down a real life shaft. Always good to know your physics
@@mr.battlecats5512 If you're referring to when a human and a potato reach terminal velocity, then you'd be correct. Terminal velocity is all about the surface area of the bottom face of an object during a fall, which is represented by the object's drag coefficient. More surface area = less aerodynamic = more air resistance. But in principle, if two objects are being affected by an acceleration due to gravity, they will accelerate at the same rate. As long as neither object reaches terminal velocity, both the person and the potato will fall at relatively the same speed across the board. However, this gets messy when you factor in air resistance once again, as it's still in affect before terminal velocity. But whether or not it is effective is, once again, dependent on each object's drag coefficient - something I don't have memorized off the top of my head. There are many factors at play when it comes to a free falling object accelerating within an atmosphere. There are ways in which your observation is right, and others in which it is wrong. It guess it all depends on what motivated you to make the claim. Are you making an informed observation, or just generalizing? Stating that the two objects will not fall at the same rate could stem from the fact that you actually understand the physics concepts behind wind resistance, but this statement is also made by people who have a lack of understanding of how free fall works. I'm not judging you if you haven't studied the physics behind this, don't worry. I just don't want to validate your claim if it's based upon a misunderstanding.
@@Encorous I have a basic understanding of physics. I was mainly generalizing, but I just rewatched the scene and the god dam potato goes between falling faster and slower than you, multiple times during the cutscene, so yeah applying fysiks to it dosent make much sense.
My fysic teacher would be like: ehEm, you FoGOt the acCeleRatioN Low-key she calculated a whole question in our book that didn't need it since it was only the first chapter questions.
I actually went through this a while back using someone else's calculation for the in game terminal velocity and the length of the cutscene, and I got about a mile. Pretty close, and I'm fairly certain the calculations were based on the average size of a mattress.
If you paid attention in high school physics, you'll know that gravity causes freefall velocities to accelerate downward at roughly 9.8 metres per second per second. This is a joke. I know that the character does not accelerate.
If you know then why make this comment in the first place. Everyone knows what acceleration is. The reason nobody has brought it up is because they know it doesn't apply here. You were the only one who felt like it needed to be said for some reason.
in the fall part, you are not actually moving at all, the platform below you is transparent and the walls around you are the ones moving. although valve didn’t make the impression of acceleration with velocity, they still made it look pretty damn realistic.
Don't need to, terminal velocity takes over with that kind of height. Edit: when the game loads this falling scene, you've already passed the acceleration phase, he's only measuring the terminal velocity until the bottom.
Or you could edit the map file in Hammer and really check. Valve hammer units are directly proportional to meters. The math in this video is, eh, not agreeable.
Assuming the meters in-game are accurate, and ignoring the fact that he completely disregards acceleration. He also makes some strange judgements, and skips the part of the fall in the wheatley betrayal level
If you payed attention in high school physics, you’d know that the average speed of a falling object in one interval won’t be the same as the average speed throughout the entire fall
Fun fact: The Pit is actually divided into 11 separate segments that all woosh past you as you stay in one place. They're tall columns that blend seamlessly into one another with "area portals", while Potatos and the elevator car are animated to look like they're falling while being completely stationary.
Makes me wonder how those long-fall boots of hers work. I know they have a spring mechanism that's supposed to hit the ground first before her to absorbe the impact, but that sounds way to simple for her to just walk away from a 2km fall like if she was hopping off the bed of a truck.

You didn't account for terminal velocity
Now if you paid attention in your physics class you'd know that there's this thing called acceleration which you didn't account for at all
in the fall part, you are not actually moving at all, the platform below you is transparent and the walls around you are the ones moving. although valve didn’t make the impression of acceleration with velocity, they still made it look pretty damn realistic.
Don't need to, terminal velocity takes over with that kind of height.
Edit: when the game loads this falling scene, you've already passed the acceleration phase, he's only measuring the terminal velocity until the bottom.
@@vermin5367 that's the point...he didn't account for terminal velocity
"high school physics"
Shout-out to everyone who learned it in 8th grade
The speed you’re falling doesn’t change you’re constantly going at terminal velocity.
This guy hasn't heard of acceleration and terminal velocity.
Or you could edit the map file in Hammer and really check. Valve hammer units are directly proportional to meters. The math in this video is, eh, not agreeable.
But are they proportional to the meters that are labeled?
Assuming the meters in-game are accurate, and ignoring the fact that he completely disregards acceleration. He also makes some strange judgements, and skips the part of the fall in the wheatley betrayal level
Without the long fall boots you'd be a splatter on the ground
If you payed attention in high school physics, you’d know that the average speed of a falling object in one interval won’t be the same as the average speed throughout the entire fall
By this match chell isnt going the terminal velocity of a human
You kinda assumed you’ve reached terminal velocity already
Fun fact: The Pit is actually divided into 11 separate segments that all woosh past you as you stay in one place. They're tall columns that blend seamlessly into one another with "area portals", while Potatos and the elevator car are animated to look like they're falling while being completely stationary.
Well now
Never knew that math could actually help me in real life with something like this.
Assuming you’ve reached terminal velocity.
Now i had a reason to pay attention in math
bro really used mathematics instead of the decompiled map to get the answer easily (1 hammer unit is 1 inch)
I wish I would concentrate in class like he did
The better Question is How Glados Survive a fall from that high
I just fucking noticed that the lenght of the video equals the time you fall in this.
Holy shit.
You didn't take into consideration the acceleration from gravity until you reach terminal velocity
Actually, he teaches you to do tasks and hides behind portal 2
If you paid attention in high school physics you’d remember that falling involves accelerating to terminal velocity during the first 14ish seconds
Man destroyed his balls at the end after running out of breath because of calculatoing
This is the budget game theory
That ending is so good
Not quite done. The speed of the fall keeps increasing due to gravity.
This is if you consider that the player is already in terminal velocity
this guy payed attention in algebra
Bro at the start I thought he was wanna sing lol
My brain is a potato when you said all the math lol
imagine someone skipped so many physics lessons so he doesn't even know about acceleration of gravity
dang long fall boots must be pretty good to be able to fall 2 kilometers and be just fine
bro had a water bucket on them💀
Now for the actual question, how big is the whole laboratory.
Bro you forgot to take into account acceleration due to gravity.
Imagine you did all that math while falling.
Really missed the chance to say "Cave Johnson. We're done here."
This is assuming you are already traveling at terminal velocity.
I think they forgot to pay attention during the acceleration lesson in Physics.
Makes me wonder how those long-fall boots of hers work. I know they have a spring mechanism that's supposed to hit the ground first before her to absorbe the impact, but that sounds way to simple for her to just walk away from a 2km fall like if she was hopping off the bed of a truck.
The facility as a whole must be the equivalent of an underground mega-metropolis. All just for "testing"...
Assuming she is already falling at terminal velocity at the beginning
Fun fact, this fall speed corresponds to the acceleration you get in one second of free fall
theyre called long fall boots for a reason
And that's why ALL THE LOOOOOREEE makes sense
They waited until high school to describe velocity to you?
