neither, no portal rules were given. Please create an Aperture support ticket.
The top of that masher is clearly protecting the cube from the rain, so I’m not sure how the rain is expected to shoot the cube out as in option B.
A.
Was going to post the correct Answers (A) but then looked at the post and though na. But if you want to know more about portals and how they would work in real life check this out. Great guy.
and his answer: https://optozorax.github.io/portal/?scene=speed_model
A, but it would have the average of the two states.
The object going into the portal has no momentum so it would be A.
No momentum in relation to what? Momentum doesn’t exist in isolation.
To the space outside of the blue portal. Moving the orange portal doesn’t drag the whole surroundings, so assuming both places are on the same planet, the momentum of the box in relations to both places is the same
As Optozorax taught us, gravity must act through the portal.
Momentum relatively to the source game engine grid.
“speedy thing go in, speedy thing come out.”
So A.
As I said, there is no “speed” in isolation. Speed is a relative property of an object and a reference frame (i.e. another object, like e.g. a planet)
Neither. The cube is not making contact with the portal at all, since the portal is on a stationary block with some speedy lines drawn on it. Speedy lines don’t nake thingy go fast - everyone witb a gel-hairstyle knows that.
EVERY GIT KNOWS FAST LINES AIN’T DA TRICK! RED IZ WOT MAKES THINGS GO FAST!!!
Next you’ll claim stink lines don’t make something stinky.
These heathens! Arguing against centuries of line faith! Draw heat wave lines around them and make them burn up!
you know only engineer/computer science nerds post on lemmy because nobody has called out that the box looks like the box from hellraiser.
no matter what you do to it, you’ll probably end up in hell.
Portals aren’t real and so work however you want them to, but people rarely consistently apply their models.
I’d say A given how they work in the games though. Only the object’s momentum is conserved. The portal doesn’t transfer momentum. There may be a slight breeze coming out of the blue end as the column of air in front of the portal-plate is pushed in, but the cube is just going to flop out.
Speedy thing did not go in
It would probably be A because of Newton’s first law of motion.
because of that law it is B ;). the cube “teleports” into the reference frame of after the portal and in this frame it is highly in motion.
it’s like you trying to jump on to a moving train, you first need to match the trains velocity (speaking relative to earth), then you are at rest in the trains frame.
this kind of thoughts is what makes special relativity so cumbersome.
The real answer is the enemies we made along the way
It’s a superposition of both states until you make a measurement
Niether. Moving surfaces break portals instantaneously.
Portal 2 has moving surfaces, with the cop-out that it’s accelerating surfaces that cause the portal to break.
spoiler
No matter that you literally put a portal on a different planet…
Portal 2 (story mode) only has laterally moving surfaces, that inherently don’t cause things to enter the portal. The moon portal is stationary in the engine.

Not providing a link to alternative platforms is my ragebait
In addition https://www.youtube.com/watch?v=DydIhwLrbMk which tries to make portals act “real” by treating them as spacetime with an unusual (but not mathematically disallowed) geometry.
Yes, they are fictional, so they behave however Valve (and fan works) want them to behave, but trying to bridge the gap between fictions and current physics models and be a fun and enlightening experience.

I’m giving so many people Fs on this assignment because you failed to read all the instructions.
The correct answer is B due to the graphical conservation of speed lines.
I think any answer is a ragebait answer because nobody here understands physics
That’s definitely a ragebait answer
I did it deliberately.
Lemmy reads more than most but people aren’t good at reading
Trick question. Fun answers are not ragebait. Serious answers (correct or incorrect) are ragebait. You get an F.
