Cube is not moving at the start and no force aside from Gravitational and normal forces are being exerted on it

but the anus is a ring muscle and can't impart lateral force

standing desks are a meme

Portals can't move relative to each other

This

Afags are people who have never taken an upper level physic class. Bfags are thinking about relativity.

What happens at the end of Portal 2 that defeats the big bad guy?

Portal 2 is not canon

Retarded retcon

they actually do, considering what we're on is spinning

What is relativity, dingus?

The distance between the portals still remains the same

yes, but their relative velocity isn't zero

This is not even possible in the real world, so really anyone who has an opinion on this subject is just wasting their time.

Dilemma version.

It literally is, otherwise their distance to each other would change.
Relative velocity is measured in distance/time, and when the distance between the objects does not chance, their relative velocity is 0m/s

Within the game physics its literally A

portals can't move

the posts I see on this fucking place

huh, right you are

Measure the distance between those portals at two points in time, when the distance does not chance, their relative velocity is 0.
Don't they teach you physics in school?

Now this is the quality discussion promt I keep coming here for.

Based satirist.

It's been some 12 years and I didn't pay attention, cut me some slack. It's not easy to try and think like someone believing in one true frame of reference. It'd still end up looking fucky anyhow if A was right, even if my statement wasn't.

what is A supposed to convey? that the distance is shortened when he moonwalks towards it?

yeah, is he getting closer to the cube, or further away from it?

A-fags are the people that got asleep on Physics lectures and just memorized something about conservation of energy and momentum without understanding a single word.

Firendly reminder: Portals do not conserve enregy. Portals do not conserve momentum relative to the environment. Not even static portals do, much less moving ones.

It all depends on the movement of the orange portal. If it stops when it hits the platform holding the cube, its A. If the portal were to continue moving, the cube would "move" relative to the portal it interacted with. However, it would plop instead of roll because the cube itself has no momentum. If the platform holding the cube dropped out right as the portal passed over it, the cube would move laterally relative to the orange portals speed, and hit the ground because gravity. Relative to the blue portals, position, it looks like it moved. So not quite B, because the cube itself has no velocity, but it would certainly look like it was launched but would not actually have momentum.

Reminder that Valve themselves hav said it's A.

first post correct post

That's fucking retarded. The cube would hop a little due to the transfer of kinetic energy from the moving platform to the stationary one, but it wouldn't rocket fifteen fucking feet into the air.

>The cube would hop a little due to the transfer of kinetic energy
How much would it hop? How much kinetic energy? Maybe equal to the kinetic energy of being pushed out of the blue portal at the speed that it is being pushed out of the blue portal? Or just a little so that you can feel well?

hmmmmm......

The primary tenet of modern physics is that there are no privileged reference frames. A and B come from considering the problem from different reference frames: A is the situation where you consider the box stationary, B is where you consider the orange portal stationary. Since you get a different answer based on which reference frame you consider, the actual answer is that portals are fundamentally incompatible with modern physics (i.e., either portals can't exist, or modern physics is drastically wrong), so there's no coherent way of answering the question.

You must be fun at parties.
Back to /sci/ with you, nerd!

You must go to some pretty lame parties if people screeching "but MY reference frame is the true one!" endlessly sounds fun to you.

At least I get invited to parties, nerd

It enters the orange portal at a speed of X. This means it exits the blue portal at a speed of X. If it moves fast enough and then the platform comes to a complete stop, it will fly off.

>portals aren't real
how insightful
portals aren't hard to integrate with basic physics, it's just a spatial discontinuity
