    Ragebait answers only

    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.

    A

    In this example, the object wasn’t moving. It has no momentum to continue moving. Instead, the world around it moved. So A

    It depends. It looks like the orange portal is being moved by a hydraulic cylinder (aka laminar flow), which means the relative positions and velocities of things moving through the orange portal are conserved, and A is correct.

    If instead that’s (yuck) an air fired cylinder… Then it’s going to be B.

    If the movement is handled by a threaded rod, then the box will emerge from the blue portal spinning, and (perhaps contrary to expectations) if the orange portal is moving because of gravity, then the bouyant force of the box progressing through the portal will stop it from falling further, and the box will end up just less than halfway (because of the angle) through the blue portal.

    Portals don’t stay on moving platforms.

    But if they did, it would be A as the cube itself has no momentum.

      The speed of one thing is the same speed of the other if you change the reference point. So the cube has momentum but the moving platform does not. It’s more about having a velocity in respect to the portal it’s going in or coming out of or an average of both. Like when you jump into a portal, you come out faster on the other side. Now what if that out portal was traveling at the same rate? Would you be traveling just outside the portal or double speed (in relation to the ground and static objects in the same room)?

        Yeah, but those are moving from side to side. To my recollection, you never see a portal in a wall that’s moving in a direction that’s perpendicular to the plane it’s in.

    Ragebait aside the answer is B.

    If you had a table with a cylinder, with a ping pong ball in it, and a circular weight dropped around the top of the cylinder that hits the table, the ping pong ball will bounce due to the forces of the weight hitting the table. Enough energy would be transferred through the impact, that would cause the ball to seemingly jump up in the cylinder.

    Physics are weird.

      In that situation both portals (the inside and the outside window frame) have equal, but opposite velocities and therefore cancel out any momentum from the person.

      When dealing with OP’s scenario, only one portal is moving.

    If we’re only supposed to do ragebait answers, then anyone who passed 3rd grade science would be able to tell you the answer is obviously B

    If you actually played the game, and paid attention in physics class in highschool, then you would know the answer is clearly A, and everyone who says it is B really needed the simplified explanation from GLaDOS to understand how to play the game.

      I’ve played the game, you maintain speed whether you jump or fly in using your jet pack, no idea who this GlaDOS character is or what that funky cube is though. Abyss is the best map.

    Since nobody seemingly posted link to this absolute … Idk, gold? It’s about actually simulating space(-time?) with portals: https://youtube.com/@optozorax_en I see offspec’s comment is mentioning the guy, yeah. Tldr answer is complicated. …

    Ah, ragebait answers only. Ugh, worm! Arrrr! I am so angry roar grrrr.

    This is clearly an unbirth scenario and the A and B things are unrelated. Either way, your baby is companion cube and GladOs is the father.

    Thanks for coming to my Ted X talk.
