Why the fuck would anybody think it's B?

>>694589951
But if the platform is coming down quickly wouldn't it make the box move quickly through the portal?

Its fucking b. It's just the reverse of falling into a portal. When you jump off a cliff into a portal, you dont just pop out; you keep flying.

>>694590165
there's no transfer of momentum between the platform coming down and the companion cube. l2physics faggot

The correct answer is B

>>694590270
Spoiler alert: it's A

>>694590071
Three was this thread last night

really? i havn't seen this in months

When an object goes through a portal, what propels it further is its momentum. Imagine doing the same with a hollow rectangle. What essentially changes when the object goes through a portal is the gravitational pulls direction. Do the same with a rectangle and change the way the object is relatively positioned against it.

In order for the object to be shot out of the portal it needs to have some vector acceleration.

9th grade physics y'all

Portals cant be moving. They will disappear if not stationary.

>>694590761
The level where you have to cut poison gas lines with lasers by putting portals on moving platforms.

Read the image as "smash or pass." Kinda makes sense.

I thought it would be A at first, but I wasn't thinking with portals. The momentum of the portal is applied to the box, just like all the air before it. There would be a stream of air coming out of the blue portal as the orange one moves, it wouldn't just increase pressure.

Me? So you mean with intelligence and reason?

>>694591307
I have an autistic brother, still call people here autists

There's actually a brain surgeon who's autistic. Google it.

The correct answer is B

It all comes down to relativity. Say you are jumping from a cliff, and you are moving at a speed at say 100 mph towards the orange portal. From your point of view you are stationary and the portal is moving at 100mph towards you... and we all agree you would fly out of the blue portal at 100mph.

Now lets do the same experiment only this time you are stationary and the orange poral is moving at 100mph towards you. Due to relativity the two examples are the same, hence B is correct.

>>694589779
Portals don't work on moving surfaces
>except in this one instance in portal 2 because of some reason
But A, obviously

>>694591307
Friend is autist and I use it.
You have nothing to worry about if you aren't actually autistic .

>>694589951
it's B you moron
there is relative motion before the block enters the portal
It doesn't matter if the portal is moving or the block
you have to establish a frame of reference
if the observer is moving with the same velocity as the portal, then the block is moving toward the portal
when the block passes through the portal, you enter a new frame of reference, with the portal velocity constant between the two, which is zero
so the block will come out of the portal with the same velocity as it entered

so, B

>>694591627
Nope, full of crap, it's A.

>>694591854

momentum works at zero velocity too
if the portal is moving in the first frame
it is also moving in the second

A, It is only your momentum that is considered when going through the portal, not the momentum of the portal itself.

nothing is every stationary, once you understand that, you might be able to understand why the answer is B

think about a car moving by you at 25 mph
you are considered stationary and the car passes you at 25 mph

now consider that you are actually on a spinning surface of the earth, and are moving at say 100,000 mph. Then, the car is moving at 100,025 mph.

Then consider that the earth is moving around the sun even faster, and the sun is moving from the center of the universe. It gets too complicated. To simplify things we consider the observer (you) to be stationary and the car to be moving at the velocity that is the difference between your real velocity and its real velocity.

17 KB, 1295x742

The physics here is simple. The velocity of the box won't change regardless of where the blue (exit) portal is placed. So if we put the blue (exit) portal on the opposite side of the orange (entrance) portal it shouldn't change anything. The portals are now equivalent to a hole in the surface. Now imagine what would happen if you slammed a piece of wood with a hole in it over a box. The box doesn't move. Same concept. Now shut the hell up with the math and whatnot. You don't need numbers to figure this out, just basic logic.

Old AF bait still works well done OP.
Also A is the physically correct answer. The technically correct answer is you cant put portals on moving surfaces.

>>694593567
portal1
ˈpɔːt(ə)l/Submit
noun
noun: portal; plural noun: portals
a doorway, gate, or other entrance, especially a large and imposing one.

>>694593369
You assume that both portals move, but that is incorrect. When will people fucking get this.

The moment the box passes the orange portals threshold, it begins to move through orange at the same speed the lift is traveling. Assuming the entire box goes through, the momentum will have fully traveled through the orange portals threshold and will continue to go as if it were thrown at the same speed.

>>694589779
Whoever made this illustration is seriously retarded.

>X is moving
>Y is moving

>now replace Y with (you)

>>694593369
both portals moving in this example, momentum is conserved

>>694593897
Also to add you have to realize that the box is in fact moving the moment it passes orange because it's being forced into orange at the same speed the lift is traveling.

YOU'RE ALL FUCKING RETARDED FOR FALLING FOR THE BAIT

Goddammit, I understand your logic dipshit, I fucking knew people would make that mistake.

>Portal is moving toward box at velocity V (yeah of course)
>Box therefore is moving toward portal (true)
>therefore portal exit other portal at speed v (false)

In this case, the entire aperture laboratory, once stationary relative to you, is now moving
relaive to you without an imbalanced force being applied on either

do you REALLY not see the problem with this?
You can say force no longer matter with protals, but in that case the addition of portals makes it impossible to really know what happens with our physics.

>>694593369
wait, are you saying the portal stops moving once the box enters it?

that's a pretty important premise that isn't illustrated in OP

with this premise in mind, the portal is going to distort the fuck out of that box, or tear it apart depending on its material

when the box is half-through the portal, it will have relative momentum on the other side, but once the portal stops moving, so will the box, so the second half will have inertia to stay still while the first half will have inertia to keep moving

Okay. Now i know that a car that seems to me moving at 25 mph is actually moving at 100,025 mph and just SEEMS to be moving at 25 mph, because i am moving at 100,000 mph myself.
I got this idea.
But what does this have to do with OPs question? A or B i mean.

When we say that everything is moving at 100k, then in OPs picture the cube is moving at 100k (seeming stationary, because everything is moving at 100k) and the portal is moving at 100,050 mph.
In this example
>>694590175
the portal is moving at 100k (seeming stationary, because everything is moving at 100k) and the person who jumps is moving at 100,050.

The technically correct answer is you can't have portals.

And you sure as shit won't ever have them if you think it's literally the same as a hole in a piece of cardboard.

>>694594253
A, yes, through gravity
B, nope
C, shoot out that portal, faster the longer i was in the portals

>>694594253
A; it accelerates until it reaches terminal velocity.

B; it will crush the rod

C; the rod will collide with the end of the portal and wont be abler to move any further.

Fucking easy.

fuck, i thought it was a this whole time but think about it, the orange portale is moving around you basically (break it down inch by in) if it falls on inch around you going 5 mph you will appear at the other one going 5 mph, but the other one isnt moving. so you will basically just shoot out of the other one. fuck i hate this problem. and before you say anything yes ive taken physics blah blah blah just humor me and think about it like that

>>694594380
The portal is moving in the first frame, but shown as stationary in the second
that means that if you (the observer) were considered stationary in the first, then you need to be moving in the second
so, if the box is stationary in the first, and so were you, it would appear stationary
in the second frame, you are moving, and the box is stationary, so it would appear to be moving to you

>>694594253
This is easy
1 the pole moves downward as long as the distance stays the same
2 if you move the portal up it will still fall but then it will be free of portals for a bit
3 it will come out of the other portal just like anything else.

>>694594626
2.5 if you move the portals closer youll crush the rod

no they cant. why wouldn`t they need to? Portal comes down quick, cube stays still.

What are you trying to say here??

>>694591535

My answer is this. It's impossible and arbitrarily pointless to think about because the laws of physics do not allow for something like this to happen

>>694594380
>just SEEMS

no it doesnt just seem. everything is relative, you imbecile. it depends what you pick as the stationary point.

The point is that saying "A is moving towards B" or "B is moving towards A" is equally true in all literally cases, including OP

>>694594077
Both portals are fixed and are exerting reaction forces on the rest of the world to balance out newtons second law

However this also dependa on how the portals deal woth forces so no idea how to know for sure.

get rid of the portals, just get an empty circle, and make it fall on the cube, will the cube move?
its A chump

Just post this to the Sixty Symbols channel.

>>694594776
the answer A shows the portal and box both stationary
B shows them having different velocities
so, B is correct

I think engineers and physicist can absolutely go fuck themselves when answering this. only people who have an understanding of game development are welcome here. the portal just behaves as a hole that's it .it's literally what the code is doing making ie a path from one 3D plain to another. I know this because I wrote the code for a functioning portal in a personal game project

>>694591860

>>694591854
made sense to me, i just see it as the block was formed at the rate the piston was pushed down, so it came out of the portal at the same speed, as the block could not pass back through the portal

Take a fucking piece of paper, make a hole in it, take another piece of paper and lay on a table with a eraser on the middle of it

Hold the paper with the hole by the sides and slam it in the eraser.

A, you retarded fucks

You assume that both portal move. That is not what is happening in the OP.

>>694595088
congrats, you are smarter than most of /b/
I would not consider this an accomplishment though

>>694592628
No. That just means, the cube would appear in the exit portal at the same speed as the portal is moving. That can be any speed at all. It's not relevant. The cube itself is not moving, and no momentum of any kind had transferred to the cube since it was not physically touched by anything, it would stay at a constant zero movement and "plop", or if the exit portal.

>>694592223
the block had to be pushed through the portal

think of it as something smilar to a sringe, the block would be pushed through the protal at the speed the piston was moving

>>694595015
but think of how you will apear out of the other hole, you come out head first then shoulders then legs then feet, you are basically being pushed through the portal. imagine you are the box and you see the portal coming down at you

has anyone here ever heard of relativity? The cube is always moving it's just standing still relative to the earth.

>>694595160
fuck me harder daddy

>>694594813
Fuck the laws of physics. We write them, we barely know them, and yet we have still subverted them in many ways (planes, spaceships, time-correcting GPS).

We've never measured a single law of physics outside our solar system. The gravitational constant is derived from a single galactic point out of the entire universe and we think it's constant?

Nothing is constant. Space, time, even light can be warped and refracted to an extent.

>>694595331
i'm sorry, but the blck was set against the flooring, it had to pass through the right portal at the same rate it entered the left

>>694595331
the stationary point in the system is the portal(s), you imbecile. So the cube is moving in that frame of reference (and that's only right frame of reference for this problem). you dont understand basic relativity (not Einstein's relativity, just basic relativity

>>694594621
Thanks for your answers.
Since you first said "Everything is moving dumbass" i would expect, that im moving in both frames, as much as the box and the portals (and standing car for example) but everything at the same pace.
In the first frame, the portal is moving faster than everything other (like the DRIVING car was just moving faster than me). In the second frame the portal, the box and me, would be moving at the same pace (so appear to be stationary).

>in the second frame, you are moving, and the box is stationary, so it would appear to be moving to you
I still do not quite get it. First you say, everything is moving, then you say, in the second frame i am moving, but the box is not.
Again sorry, but i need this for dumb people. Or...at least absolutely not good with physics

>>694595331
the portal is a hole through spacetime
so the entry portal and exit portal are the same location/velocity
in the first frame of the OP, there is obviously a difference in velocity between the box and the entry portal
if the entry and exit portal are the same, and therefore have the same velocity, then the box has a velocity relative to the portal
then, the box must have a velocity to the exit portal, so it would come out of the exit portal with a velocity equal to the difference in velocity between the box and portal in the first frame

This thread is a testament that /b/ will literally argue over fucking anything.

>>694595749
everything is moving was the reason I said you have to think about the speed relative to something
lets take the portal to be the thing we assume is stationary and all other speeds will be relative to it.

So, the portal is stationary in the first frame and is stationary in the second frame.
In the first frame, the box is moving toward the portal.
In the second frame, the box is moving away from the portal.

I think this should be settled through trial by combat. I volunteer as tribute to represent A

nope, thats just plain wrong

>>694595873
it's not quite as bad as the PEMDAS threads

>>694594992
Since in Portal those portals can't move like this but you seem to think like this:
If orange is moving, blue must be moving too.
But wouldn't that be like this >>694593369 ?
There both portals have the same velocity. but if it would happen like this, the block would have non, to fly out of the blue one

>>694596065
this should be settled via DINO FIGHT!

"You seem to understand how portals effect forward momentum. Or to be more precise. How it does not" (Not perfect quote but I remember her saying something like that)

That's what Glados said in the first portal game.

So shove your flying box up your asshole and pick A

>>694596275
no, this guys picture is wrong because the door stops
why would it stop?
how do you stop a fucking moving portal?
I imagine this is why you can't put a portal on a moving surface, the surface would move through the portal and the portal would stay still

Em..hello
Just want to say, u can't keep portal on moving structures, mean probably if both portals were in static positions to each other it would be possible since the game allows portals despite of fact that earth is spinning and shit, but i won't allow moving wall have a portal.

>>694592223
This picture is wrong because in case of portals, ground will move too.

Portals are fixed in space and cannot move. The answer is neither as the cube would get smashed by a portal less piston.

>>694589779
I cant believe this thread is still alive for so long when the answer is so obvious. Holy shit.

The block will shoot out of the blue portal with the same velocity and angle that the orange portal "hits" it with

>>694596018
How can we assume "the portal" is stationary, while in OPs pic there are two sides of the portal- one moving, the other stationary (or one faster moving, and the other one at the same speed, anything else is, to be exact)

>>694594488
But it is.

>>694589779
A yyyyy lmao

>>694596746
Who cares what you would allow?
You`re not even my real dad!

>>694596879
the portal is one object, accessed by two frames of reference.
this goes back to when I said everything is moving
in any frame of reference, you define how the frame of reference is moving. In this case I'm saying our frame of reference for both the entry and exit are equal to the velocity of the portal, so it appears that the portal is stationary.

>>694591178
fuck me that's true

>>694594144
Of course it is illustrated you fucking twat waffle. The portal is clearly smaller than the platform it is being rammed against. Also It'll just plop out. Having most of the cube hanging out at an angle will pull the rest through.

>>694596443
>why would it stop?
Hypothetical question. But it DOES stop in OPs pic

>>694596443
Because the portal stops which is the door way the object isn't moving. Its fine if your retarded i expected to run into some in this thread. There is no energy that's being put on the block for it to fly out of the hole. So it will remain position and just slide down the ramp.

>>694597113
how fast is the portal moving in the first frame?
how heavy is the box?
what is the rate of gravity in this location?

hell, what if gravity is actually upside-down, and the box is being held by magnets in the first frame?

too many variables
solution is undefined

>>694589779
Neither. It acts like there is no portal there. The portal can't be on a moving wall.

>>694597191
wouldn't the portal just cut through any surface like a hole saw?
it's a fucking portal, not a hula hoop

>>694597331
If the portal is "attached" it the top platform it stops moving when the top and bottom smash together. It'd have to either come off or be bigger.

What about the transfer of the portals momentum on the cube? It's not just a hole, the portal itself exists.

>>694589779
could only be B. because you can't place portals on moving surfaces, so the lower piston have to move and catapult the cube through the portal

the entire concept of a portal is ridiculous since it violates general relativity

>>694597696
how do you attach a portal to a moving surface?
that doesn't make any sense
the portal is moving and the surface is moving, they just happen to be next to each other
the portal is going to beast right through any surface
it's a fucking portal

>>694598038
velocity, not force, but correct illustration!

>>694598079
whether any surface is moving or not is just a matter of perspective.

So are the people saying B just trolling or do people really not understand how simple the answer to this is?

>>694598172
yeah, have you?
inertia doesn't even come into play here, if you consider everything to be at a constant velocity

Sure, gravity will apply and inertia will affect that, but as far as the initial velocity before and after the portal is traversed, inertia and gravity don't make a ton of difference

>>694598263
then why use the design of the game you fuckface

you dont know what inertia is. i think youre mistaking inertia for friction of some sort, which is just sad.

I'm not talking about the game at all, haven't considered it in the entire thread

I've barely even played it
I just like physics

>>694598377
It's two colored holes and a box. If they want you to assume all portal rules then the picture would say so.

>>694592223
it's not "just" a doorway

the whole space around you would move

>>694598613
velocity doesn't change unless acted on by an outside force
I was saying that you don't need to examine the forces in this small window of time we are looking at
inertia doesn't matter until you start examining the forces
