A. With B the block would have to be moving not the portal.

A

B. Conservation of momentum. It's not going to pass through the portal then instantly come to a stop.

A.
Because the cube has no momentum to carry and the orange portal is moving towards the cube, but this wouldnt give the cube momentum to shoot out like B. There is no force to push the cube. Maybe if the bottom platform was moving up the cube could shoot out.

A. The block doesn't gain momentum, it merely changes positron.

B. - If you imagine the problem as the platform as the cube moving up towards the portal, its momentum would be carried through to the other side. This is equivalent to the original problem

the cube will be crushed because orange portal will disappear

...

Thankfully there's oldass shit posted like this, and a plethora of faggot niggers to take the bait, to break up the monotony of the trap, rate my cock, niggercock and plain old regular faggot threads, wooo boy, Sup Forums is still circling the drain, hasn't flushed to complete shit sewage yet!

On a conveyer belt, yes. On that, no. The uprights would prevent wing clearance.

You know you're wrong, right? Seems to elaborate to be bait.

B. It doesnt matter which system is moving because only the relative movement counts. Imagine looking in to the blue portal. The cube comes at you with high speed and the momentum wont just suddenly disappear.

explain the difference

B because the block still has velocity relative to the orange portal. Imagine if the portal and the ball were switched, it would have the same velocity.

If the engines are running and the conveyor belt doesn't slow it down enough, I don't see a reason why it shouldn't work.

momentum is the object's velocity at the moment of entering the portal, so it doesn't really matter which one is moving
B is the obvious answer for anyone who knows anything about physics

Can someone just set up a portal map that tests this

Dude, if you have a basketball suspended in air and move a hula hoop super fast towards it the ball doesn't move when passing through but if you throw a basketball through a non moving hula hoop it shoots out the other side. Unless portals have the ability to propel something just based on how they work then it won't go flying out.

All momentum is relative to its surroundings. Just remember that you're standing, on a planet that's evolving, and revolving at 900 miles per hour. So the cube, relative to the portal, has momentum and will maintain the momentum through the portal. In layman's term's "speedy thing (relative to the portal) goes in, speedy thing (relative to the portal) comes out." However, let's assume A. is the correct answer instead. If momentum is not transferred to the cube at all, and the cube has 0 velocity exiting the portal, the first layer of atoms through the portal would have a force exerted on it by more atoms exiting the portal at a rate equal to the speed of the moving portal. So either it would turn into solution B as the box presses on itself as more exits or implode under the force.

What even are frames of reference?

But it does move relative to the hula hoop though.

I'm not saying answer B is correct but it seems like it could be.

Oh I see what you're thinking. But a place gets lift from the air moving under the wings, the engines just drive it forward. If it's not moving through the air it won't get any lift.

Yeah but it is moving through the air though.

Just a bit slower than usually when taking off.

Yes it does shoot out, relative to the coordinate system of the ring. The only difference is that the portal makes the system change from moving to not moving from your perspective. So the cube goes from not moving to moving.

But the conveyor belt is moving against the direction of travel, not with it, so the wheels are turning but it's not moving. Just like when you run on a treadmill you don't make any net movement through the air

There are moving portals in Portal 2 (the ones used to cut the poison gas pipes with lasers).

The cube isn't even relative to the portal, it's in contrast with, fucking idiots. The cube is stationary, with no potential energy. Portals are just holes, they don't propel objects through them, troll harder niggers.

Don't bother explaining to him. He's either stupid or a troll.

But the engines don't turn the wheels.

They push the plane forward by propelling air backward.

If the conveyor belt doesn't push the plane back faster than the engines push it forward it should move forward and even take of if it gets fast enough.

Hey kid, you aren't making sense. A stationary object is not relative to a moving object, it is in contrast with.

What the fuck, you guys are stupid, you're trying to sound smart but you're not smart enough to do so convincingly.

why doesnt somebody just try it and see what happens then we will know who is right

>The cube is stationary, with no potential energy

Because portals don't exist.

ain't clicking that bullshit nigga

...

Maybe he is stupid. I'm a bit stupid. Doesn't mean I shouldn't try explain. Sure this dude understands stuff I don't.

Well in that scenario it's just a plane moving forward and taking off. Basically, you've got to be cutting forward though the air fast enough for the wings to supply lift to the plane.

technically correct, but they are only moving in their plane, not perpendicular to it.
There are no portals that can move like this.

Exactly that's what I've been trying to say the whole time.

try it in the game Portal, not irl

The difference is that the energy in the cube is not kinetic, it's unmoving. It's like dropping a open window on a box, the box doesn't move. Though in this case, the output changes the slope of the landing pad it was originally on, therefore it falls just slightly, probably rotating 45 degrees and hitting the ground.

...

But the physics engine in portal might not have the correct answer.

A, because the object itself isn't moving, in Portal they say that portals do not affect speed by themselves you need to jump into it/run into it otherwise A would happen

Indoor think you understand what "relative" means.

...

It's own sides would touch, infinitely creating a blockade. It wouldn't ever be able to close.

Newton's law of motion, you faggot. Learn science.

You can hover over it as see it's monty python. If you don't know what it is you are either too young or uncultured. The point I'm trying to make is that all things are constantly moving through space and to say something has 0 potential energy when there are other things than the ground to compare it with is just ludicrous.

This makes a lot of sense.

Looks like this might be the final answer boys.

A.
It's always going to be A.

Get out of here Sup Forums, this question has already been answered a million times. Both answers are right, it depends on whether the portal can transfer energy or not (somethin like that, dont really care)

Except that the platform isn't moving up and the cube has zero momentum and you're a dumbass.

The physics engine is canon.

Relative to the upper platform, the lower platform is moving up.

Together with the whole planet.
