>speedometer

The answer is B because it's not portals moving around it's the universe moving around the portals

>A

The block has no momentum, it just instantaneously appears in a new frame of reference and is now subject to gravity from a new direction.

>it will read 0
That depends on the frame of reference.

If you don't understand that there is no privileged frame of reference, you are not smart enough to have an opinion here.

correct
B fags assume that because you see the cube "moving" out of the blue portal it must have momentum

if you were the cube, as soon as the orange portal passes over you you're sucked up and sent flying out of blue.... This is what bfags actually think will happen

A-tards don't know how to use the following words:
-Force
-Motion
-Movement
-Momentum
-Velocity
-Still
-Perspective

>it just instantaneously appears
Not how portals work in the game. It comes through the portal as if the portal is a doorway. People use the doorway analogy to argue for A as well, but it's also easy to justify B when you imagine the cube emerging from the blue side of that "doorway". It needs to be moving with respect to the blue portal in order to come out of it. That's unavoidable. Now if you say A happens then you need to justify why the motion stops.

>but it's not REAL motion, because of how space is warping!
Nice headcanon but don't expect everyone to take it as established fact.

This one time my sister didn't listen to me and decided to use a hula hoop. I was pissed off and scared and told her to be careful but kids are gonna be kids. The hoop dropped around her and she got flung about 2 blocks away, shattering her pelvis and legs. She now has to shit in a bag and I clean up after her everday. It's B, because I know the danger of a ring going around you without touching you - well, my sister does anyways

This is the classic midwit opinion
The cube does NOT move out of B, space moves around the cube
From the cubes frame of reference there is no movement, that's all that matters, it won't suddenly fly out of blue

>drop a hula hoop on top of a cube
>the cube should be sent flying
this is what Bfags actually believe

I'll repost this because it leads to interesting discussion

B A S E D

There is nothing in the games that suggests portals can do anything but connect two points in space. You are going to need to back up your statement rather than just describe an outcome. Otherwise, I can just say the cube DOES move out of B and it will carry just as much weight.

>Afag
>"speedometer"
checks out

You are the cube, nothing touches you, no force is applied
When I drop a hoola hoop over myself, from the hoops perspective I am moving, in objective reality no force has been applied to me

>but portals aren't hoops and only one end is moving
Prove how that would magically add momentum to an object, other wise you're making a massive assumption with no evidence

see midwit

This isnt even hard and Im pretty sure you can do this in game.

The initial state of this problem is that the cube is moving at a high velocity with respect to the orange portal.

Take note of the people who disagree with this statement. Those people don't understand the statement, because they don't understand anything about physics. They are idiots and are not qualified to have an opinion about this problem. I don't really take an interest in A vs B in these threads anymore, because you don't even have to delve all the way into this thought experiment in order to find idiots. All you have to do is post an objectively true statement and watch people try to disagree with it. It's hilarious.

movement is relatable

i mean see maybe i'm the retard, anyway bfags are still low iq

the portal doesn't add any momentum, the cube's already moving in the entrance's reference frame

Doesn't the ending of Portal 2 with how the characters and objects interacted with the portal placed on the moon kinda disprove B?

The issue is that the cube never gains any velocity, which it would have to in B
Bfags STILL haven't explained how the cube suddenly starts flying

in the cubes reference frame it doesn't move, so b is impossible
what mystical phenomenon causes the cube so go from stationary to flying through the air?

they can't prove that because they don't give momentum to objects otherwise in game you couldn't stand halfway in one and remain motionless

no, they disprove A
if the portals worked as they think they do whatever comes out would go sideways extremely fast since the moon is moving around the earth at very high speed, and whatever comes through wouldn't inherit that speed

B because it's my fetish

This doesn't do anything to explain how you came to the conclusion that a portal can do something other than just connect two points in space. Even if I just give up and accept that this post were to disprove B, it still does nothing to say why A would be able to happen.

If people don't respond to
>BUT WHERE DID THE VELOCITY COME FROM?
>BUT WHERE DID THE VELOCITY COME FROM?
>BUT WHERE DID THE VELOCITY COME FROM?
>BUT WHERE DID THE VELOCITY COME FROM?
>BUT WHERE DID THE VELOCITY COME FROM?
then it's probably because they're WAY past accepting that portals simply don't conserve energy or momentum. Momentum conservation is broken when portals change the direction of a moving object, and energy conservation is broken when you use two portals (one above the other) to gain gravitational potential energy with no loss in kinetic energy. The only way that we can say portals don't violate conservation of energy is to assume that they are powered by some unseen energy source, in which case that energy source could also be the excuse for an object's momentum being changed.

Do you actually not know how a vacuum works

It's A. B fags are so up their own ass about their """education""", they forgot about common sense. The portal NEVER comes into contact with the cube, but the cube magically overcomes the forces of gravity to get flung.
