if you fix a point in the portals surface and measure the distance between the point and the cube it wouldnt matter which one of the two, the surface or the cube were the one in movement the distance would always be the same as long as the velocity was the same, taking in consideration that the velocity is the derivate of the position in dt, the correct option would be B

it doesnt need that much to prove that the velocity would not be 0, if you consider the distance between the blue portal and the cube as being the distance between the orange portal and the cube then as time advances the distance between the two would not be constant so the velocity between the two would not be null

what happens if the portal stops moving down when it has swallowed the cube halfway. The cube which has travelled through the portal now has momentum which it imparts back to the untransported half and it gets partially shot out? Even just during the process of the cube going through can only one part of the cube really have the momentum?

[Anonymous No.]

>>46851231
>The cube which has travelled through the portal now has momentum which it imparts back to the untransported half and it gets partially shot out?
Basically yes, the front half will have momentum and the back half won't. Because a cube is a rigid object, the momentum will equalize throughout and you end up with the whole cube moving at roughly half speed.

The underlying supposition here is flawed. Portals themselves neither add nor remove momentum from an object, they just change where an object exists. The object keeps it's own momentum- from the cube's perspective it hasn't moved- everything else has moved around it.

I want to believe you so bad but the first part with the moving train example makes me have second guesses about how the portals actually work.

Like if we have the two portals moving at the same speed (10m/s) and the orange one takes in a stationary cube, would it just plop out the blue one and then keep getting pushed along by the blue portal at its speed (10 m/s)?
What do you think?

Therefore B is correct.

>>46849684
If you sit on the piece of wall holding the portal, you would see the rest of the laboratory moving towards you, including the cube throwing itself into the portal at high speed, and that energy being conserved, it would fly off the opposite portal.

In other words kinetic energy is relative to the frame of reference. Was true in Newton's times, it's even more true in Einstein's relativity.

[Anonymous No.]

The orange portal platform speed will only affect the speed with with which the cube emerges from the blue portal. The cube itself doesn't have any speed, so it will not "shoot out" of the blue portal. If it's Portal's portals then it's simply like moving doorway towards stationary object, for example chair.

[Anonymous No.]

>>46863289
>the portals actually work
its definitely not by any real physics. moving objects going through a portal keep moving, stationary objects stay stationary. thats it

[Anonymous No.]

>>46889121
Now, what would be interesting is if we keep orange portal stationary and blue portal would be attached to ceiling "facing" down. Then we slowly move cube up towards orange portal. Once half of the cube passes the portal, would the remaining be sucked up into it because more than half of it's mass is being pulled by gravity on the other side of the portal?

for this one, A is wrong
if the object is on a platform in which the object is given momentum, the object retains the velocity when exiting the portal

I don't know if it's B but it definitely can't be A. Maybe a false dichotomy

[Anonymous No.]

>>46889121
What about a stationary man standing right outside the blue portal where the cube would come out? Seems like the unless the cube phases through the man, the two would collide and impart a force on one another despite the man being stationary

[Anonymous No.]

If we go by conventional physics the answer is B but since portals are devices that violate the laws of physics as we know them it might be A (depending on how exactly they work) so there really is no point debating this

[Anonymous No.]

Its A because the cube simply appears on the other side of the blue portal.

[Anonymous No.]

Funny that b-tards actually believe that if you'd drop the portal halfway through the cube, the cube will "jump" up (or tear in half, whatever the retatds believe). Relative velocity and actual kinetic energy are not the same things. We know that portals can transfer potential energy from them but nothing about kinetic.

[Anonymous No.]

>>46892678
>>46889121 here I changed my mind, it's B. Or actually, depending on the platform speed it could be anything from A to B. My reasoning:

Imagine the platform with orange portal is much bigger. The portal is bigger too. It's so big that it can swallow the entire platform with a cube and keeps going down, swallowing the pole the platform with cube is attached to. What happens on the other side is, the entire platform with cube on it is leaving the blue portal at the speed of orange portal platform descending speed. Now if orange platform suddenly stopped while still "swallowing" the pole of the cube platform, on the other side the platform would stop emerging as well, however the cube would still maintain the momentum from the previous movement and "jump" off the platform in the same direction the platform it was on was moving towards. How far it will go, before completely succumbing yo gravity, depends on it's initial speed.

Situation showed on the picture is actually no different from the above, slightly altered scenario.

So, B-fags were right all along, and I was wrong.

Since the cube itself doesn't have any momentum, A would been the correct answer.

[Anonymous No.]

>>46848567
It's B, because the cube approaches the blue portal rapidly and has to preserve momentum. That it doesn't move in the first picture is an issue of relativity, its perspective is correct in its reference frame.

[Anonymous No.]

>>46895719
>the cube approaches the blue portal rapidly
It doesn't. It's a portal that's approaching the cube which makes A correct

>>46895710
It does have momentum when leaving the blue portal. It's leaving the blue portal at the speed of orange portal descending.

It does have momentum though. The front of the cube gets pushed forward by the back of the cube to get through the portal at a high speed. Unless something is stopping it, it has to keep going. Getting out of the portal itself is momentum. If it would have no momentum it wouldn't even leave the portal cause it doesn't have the energy.

>>46896436
If a train hits you, I assure you you will have momentum even when standing still. Imagine the cube is made out of multiple components, which it is. The front of the cube cannot just plop down and take its time, cause the components behind are pushing it and telling it to hurry the fuck up because they also have to get out, at the speed of the portal coming down.

If the portal gets down in half a second, every part of the cube has to get out in half a second. If the portal gets down in a millisecond, every part of the cube has to, one after another, get out all together in a millisecond at tremendeous speed.

Every part of the cube is thus being pushed out at the speed of the portal coming down. Also not samefagging.

>>46848567
Is there even a single moving portal that can be used in the games? I don't remember any.
I certainly remember that you can't put a portal on any moving surface, so this scenario is inherently just a mental exercise with no correct answer. It is entirely dependent on which arbitrary rule you want to apply to the portal.

[Anonymous No.]

>>46896731
Portals have no space, weight, speed, volume or any physical quality

[Anonymous No.]

>>46898947
The cube does. If the cube's height is H and the portal swallows it in a second, the cube has to leave the portal at the speed of H per second. If it would go slower, it would leave the portal all squished. This speed is the same as the descending portal's speed. The cube can't maintain structural integrity if it doesn't go as fast as the portal.

Argue against that post my friend, not me. Are you saying this:

Portals have a position? The fuck are you on about, anon.

[Anonymous No.]

>>46900139
What do you mean? Everything that goes in a portal has to get out at the other end at the same time right? So if the tiniest sliver of the cube enters the portal, it immediately has to get out the other end. So does the next sliver, so does the next. So if slivers go in fast, they have to get out fast. One atom after another have to go in out at the exact same time.

If you're on a train with 99 other people and all have to go out in a second and you're in the front, you cannot exit the door and just stand there, the other 99 will push you out. You have to go at least as fast as the physical space you all occupy in a second. You'll be catapulted out.

Now imagine you're all handcuffed together. You still have to go that speed, all together now because you're bound together.

Now you're not a person but atoms bound together in a cube. If the cube is swallowed up at one cubelength in x seconds, you have to leave at one cubelength in x seconds. You cannot stand still.

Whether the portal moves or the cube moves is relative. If you're standing next to the cube on the pedestal the portal moves towards it and the cube is stationary, if you're looking through the blue portal the cube moves.
