... there is no such thing as "spinning backwards". The centrifuge spinning the opposite direction would still produce the same forces.

Yes, but the passengers are seated and facing a certain direction. A car accelerating in drive produces the same force as a car accelerating in reverse, but the driver will experience it very differently. It's a sensation of push vs pull.

That doesn't work with centrifugal force. Spinning clockwise or counterclockwise, people will feel the same thing. Linear forces are different, because you have a negative and positive direction.

Thank you, yes. I'm sorry, I think I've been confusing spin with rotation (the direction the capsule itself is turned.) I don't want to put any more bad science out there so I'll say no more unless I can find a concrete link instead of dated memory.

If it helps to visualize it, I believe that the capsules can only tilt about 20 - 30 degrees in any direction.

The passengers aren't facing "forward" along the perimeter of the circle, they're sitting with their backs along the outside of the circle looking in. The spin is right/left from the riders' perspective, not front/back.

I want this!
No worries, I've done enough for both of us.

And if the capsule was rotated around so you were facing out, not in? (Edit: While ETC does now produce a gyroscopic capsule with full movement, I don't believe the Epcot version has the full range of movement.)

I'm coming close to vomiting just reading about spinning and negative Gs,,,ugh(changes threads)

Someone who knows better please correct me if I'm wrong, but I'm pretty sure there is no mechanism in place for that axis of rotation. Even if you re-affixed the capsules to face outward, about half of the ride makes use of the centrifuge to simulate forward motion, which would be lost if the capsules didn't face the center.
It never made me nauseous until one time I rode it slightly headachey. Felt queasy for an hour afterwards. But then, after that, no more problems.

Ok... Imagine the nose of the above airplane pointing towards the center of the circle... With the riders in a capsule sitting in the tail, facing center.
the below is all from memory, so I may have exact numbers off.
IIRC, the capsules only have motion in pitch and roll, no yaw. Planetary motion is the motion of the arms holding the capsules around the center axis.
I believe the capsules had about 15 degrees forward pitch and something like 30 degrees backward pitch. I want to say roll was a smaller range, but don't remember the details.
As noted, the simulated zero G would be created Pitching forward and slowing planetary rotation sub threshold level.. So regular gravity pulls you forward.... Doing this immediately after the higher g of the launch simulation for a short period will create that effect briefly, as the capsules can't rotate 360degrees like the full simulator the company builds and uses for launch training.
Hope this helps.

Or just emulate the 'vomit comet' flight profile.

Because the nasa / military grade simulators are designed around a single occupant. Through put is not a consideration. They are designed with the rider facing along the path of travel and have 360 degree movement in pitch and roll. High g onset (rapid acceleration and deceleration) to simulate military aircraft..
