Have a look at this article about the Cycloid motion of a point on a wheel: https://en.wikipedia.org/wiki/Cycloid...

But the wheel surfaces are not parallel at the entry and the exit. As the ball moves toward the point of release, the Z force provides a...

Of course you should say "moving relative to the ground". If the cart on which the wheel is attached is moving at speed v then the...

I'd prefer to say it includes an electric field, but "has voltage" will do, yes. Do note @weirdoguy's comment in #9, though. Although...

Not a lot of people know this but a lot of these scenes were filmed on Earth to save production costs.

If ##g## is small but nonzero, then so is ##p=\rho g h##.

That is also an isobaric compression, requiring more work. Do you mean like an isothermal expansion? Where both work is released and...
