Wouldn't it be friction? The electromagnetic fields would be responsible for accelerating the magnets under the train. But the friction between the magnets and the train is responsible for accelerating the train. The friction between your feet and the train is responsible for accelerating you.

Thank you all.

We're hitting the silicon barrier so we might jump to a new type of computing, right? So would my knowledge all go to waste if we move to optical computing for example?

So would you be technically correct in saying that you are weightless when you are in orbit with Earth despite that your weight causes you to stay in orbit?

I'm intrigued to get one but I'm concerned if there will be any social consequences.

I think it's a matter of mutual respect and tolerance. If someone passed away that you looked up to or are related to, would you like it if people celebrated? Also, criticizing someone when they're dead feels similar to talking behind someone's back and/or being cowardly.

You are accelerating at constant acceleration without anything physically touching you. Do you feel anything? What would an accelerometer read if the same force is applied to the accelerometer without anything physically touching the accelerometer? What would an accelerometer read if the no...

So relative to the frame of reference of the ship, the astronauts appear to be weightless, but they are not actually weightless. However, do the astronauts not feel the pull of the force? If you're in an zero-acceleration frame of reference, you cannot tell what velocity you are traveling at...

He should've changed: to: I thought it would be fairly obvious given that he said: i.e. he was referring to the ugly abomination in the attachments. Solving a simpler problem: $$a=\frac { dv }{ dt } \\ \int { adt } =\int { dv } \\ v(t)=at+{ v }_{ 0 }\quad (1)\\ \int { v(t) } dt=\int {...

I concur. This has tech-support-nightmare written all over it. Also, Avant uses IE/FF/Chrome engines so it wouldn't fix anything.

If they're orbiting Earth, then they're in uniform circular motion. And if they're in uniform circular motion, then they experience a centripetal force (and thus centripetal acceleration) towards the center of Earth. Therefore, they are constantly accelerating (direction changes, magnitude does...
