We all agree it's B, right?

the original scenario already doesn't happen in the game. it's all a hypothetical problem. though I wouldn't expect an atard to understand so I'll explain:
the gif shows that velocity depends on perspective. in the third shot, the cube goes from being at an apparent standstill to moving, just by passing through portals.

It does a very tiny hop that's closer to A

where does the energy for B come from?

from the platform with the orange portal

when does the orange portal platform touch the cube?

Soz babe, but it's been proven A.

It doesn't. I can see where you're going with this though. Portals can alter an object's velocity. They do in game when they change the direction of your velocity. They do this all without touching the player.

didn't read. the cube in that gif is magically floating through the air and through the portal - an impossibility in the real game unless-
1) the man throws throws the cube at a thousand miles per hour. or
2) it's riding through an excursion funnel, in which the object would be moving at a fixed rate.

it's sliding along a frictionless plane, inside a theoretical train car that maintains a perfect vacuum, being thrown by robots. literal physics 101 setup shit.

The real answer is that things with no momentum can’t enter portals

The momentum of the portals don't transfer to the momentum of the cube.
What are you asking to be explained? Look at the gif again, the top person literally throws the cube, which doesn't change speed at all when viewed locally. The cube is not stationary and holds the same speed throughout the entire gif.

you are so SO close to understanding.
>which doesn't change speed at all when viewed locally
what if your "local" was the platform with the orange portal?

the cube has momentum relative to the orange portal

momentum is relative to frame of reference retard.

B fags think that moving a window around something would cause it to go flying

/thread.
and every fucking repost of this thread ever

right. this gif shows two frames of reference. one going at the speed of the train and one going at the speed of the ground. they are both true.
it shows that a cube can appear to be not moving relative to your frame of reference (guy on ground), and appear to gain speed when it goes through portals.

Ohnonono
How will bfags ever recover

when does a portal alter your velocity?
speedy object goes in portal, speedy object comes out portal.

The cube would still fall as we are measuring the "locality" of the cube. Portals (if we're using the definitions of the game) only connect two points. A similar thought would be like trying to swat the cube with a large plank with a hole big enough for the cube. It doesn't matter how hard you swing the plank, the cubes speed and momentum won't be affected.

velocity is speed and direction
a portal alters your direction, therefore it alters your velocity.
and before you say "there's a difference!", there isn't

>bfags already relying on relativity arguments
we won Abros.

There is literally no difference between these two.

once again, a hoop analogy retard. see the cube has momentum relative to the orange portal. It is *literally* the same as if the cube platform were zooming towards the orange portal.

No its not. T. Gaben himself

ok, cool, they change your direction.
where does the speed come from?

the cube already had speed relative to the orange portal.
ALL velocity is relative. There is no such thing as absolute velocity, or an object being absolutely not moving.

afags explain this
and don't you dare fucking say air pressure

Attached: 1636237224470.webm (1280x550, 2.88M)

Yep it's air pressure. You can even see the wind

it only alters the vector of your velocity but yeah it's correct to say.

>box doesn't move
>box moves
>no difference

so by that logic if i were to make a mechanism that sends a doorframe at me at 500 miles per hours and then stops the doorframe the moment its at the same position at me, i will suddenly start flying. because i am moving relative to the doorframe before it stops.

The box doesn't move in either

I'm VACOOOOOOOOOMING

I don't understand how you all keep coming back to the fucking hula hoop analogy. see There's a difference when just one side of a (hoop, hole, door, portal) is moving vs. when both sides are moving.

>can see the box moving
>The box doesn't move

I'm convinced all Afags are just trolling at this point. There's no way people can be this retarded

Sure, but first explain how a human being unprotected out in the vacuum of space is able to survive 31 seconds without their lungs bursting or being barbecued by radiation.

No there isn't.
How does increasing the space you teleport through change anything other than the distance you were teleported

the box isnt moving. its being displaced.

There is no answer as portals, as defined in the games, are ill-defined with respect to our understanding of physics. Portals respect neither conservation of momentum nor frames of reference (an object can have non-zero velocity with respect to itself with moving portals.)

This is the power of a bfags mind

look at the gif closely. on the left side, where both sides of the portal are moving together, the cube doesn't move. This is like moving a doorframe over yourself.
On the right side, where only one side of the portal is moving, the cube appears to move out of the stationary side. That's the difference.

I swear you afags find new words to describe movement in every thread

Yeah but because we aren't monkeys we can understand that the cube isn't actually moving the portal is

There are no "two sides" to a portal.

op btfo

That's the main mechanic of the game retard

See that's the fun thing about the relativity of velocity. If something looks like it's moving, it is! from your perspective at least.
Seriously take a high school physics class. You might enjoy it.

/thread

riddle me this retard: how does relativity add energy to the cube?

No. If you the observer moved to make it look like the cube was moving that doesn't make the cube actually move. Obviously.

Ok i'm gonna blow your mind: kinetic energy is relative.
An object's kinetic energy is defined as the energy it takes to change it from "moving" to "at rest". "moving" and "at rest" are both relative.
The cube had velocity, therefore momentum, therefore kinetic energy relative to the orange portal.

There's no such thing as absolute velocity. If I start moving, the object is also moving relative to me.
Galilean invariance.
