Dude I was giving you an out. You could've been all "haha just kidding" and saved some face.
You shouldn't try to force someone into liking something just because you like it. That's not okay. Especially when they've politely and repeatedly expressed disinterest. If all they do is web browsing and writing then why would they even need Linux?
The people are possessed of no kinetic energy, the train cannot physically act upon the people since the portal is intangible. There's no way for the train to transfer any kinetic energy to the people, and there's no other force that could act on the people. No kinetic energy going in = no kinetic energy coming out.
I just don't agree that's how it would work. You can't gain momentum simply by passing through a portal. The portal cannot create momentum. The object passing through has no kinetic energy going in, it can't have kinetic energy coming out. It would exit the portal at the velocity of the first portal, as the entry portal passes over the object, and then the object would drop to the ground.
Yes but it wouldn't be possessed of any momentum, it only appears to be moving because the train is moving. As soon as it cleared the portal it would drop straight to the ground.
"Velocity is relative" doesn't really apply here. The question is momentum, the pedestrians have none, the portal will pass right around them. Imagine the exit portal is on the back of the train, it would be as if a large hollow tube was passing around the pedestrians, they would still be laying there stationary.
But the pedestrians have no momentum, only the portal has momentum.
Replace the portal with a normal open doorway, or that gameshow "hole in the wall", when someone passes through the hole, they aren't launched out of the other side, they're still just standing there as the door passes around them.
I dont know why you believe thats how language works, its not. Everyone in Texas pronouncing "nuclear" "nukular" instead of "noo-clee-ar" doesn't make it correct. It still comes from the root word "nucleus", not "nukulus". The majority are objectively wrong, and there are no arguments to be made to the contrary.
If you want to be wrong on purpose, go for it, just stop pretending otherwise. You're embarrassing yourself and all English speakers.
Dude fuck off back to middle school. This place is for grown-ups.
