From 1:33 onward is my favourite carousel shot in the whole film.
-
notice how nothing stands loose as if it had to be secured to not fall down? ;) amazing stuff for the time though
-
Thank you for presenting the facts of centripetal motion. AND centrifugal motion!
-
I actually use this jogging scene as an inspiration for when I go jogging- inside my condo or on the street. Makes one feel younger and more athletic!!!
-
Something like this starts in the 2040s.

Also, for those who are curious, the centrifuge is the reason why the space-ship was spinning end-over-end in the sequel, "2010." When the bearings of the centrifuge froze & locked up over time, in order for perpendicular momentum to be preserved in space, all that rotating motion transferred to the rest of the ship itself, causing it to spin end-over-end. (All this was explained in the book, but not the film, which is why I know this...)

If you watch this scene carefully, you can see Kubrick had Lockwood run in two directions in the centrifuge. He also inverted the film in part of this scene. You can use the hibernation beds as a reference (e.g., 0.25, 0.47, 1.00). This must have been on purpose because they'd need to spin the centrifuge the other direction for some shots. And Kubrick is said to have been a perfectionist - no way would that be an accident. The question is why? Are we looking at Frank Poole in another dimension?
-
Putting the science back in science-fiction. I love that book/movie, it is definitely one of the greatest sci-fi work ever made.
-
Question, what happens if you jump under that force? If the gravity is lower towards the center, then would you fall normally or just be suspended there? It confuses me.

his legs are HOT.

1:35 On the set, they obviously can't be spinning the cylinder so fast as to simulate 1 atmosphere of gravity all along the interior floor. So, unless there's some sort of seamless split screen going on here, Frank must be hanging upside down when David descends the stairs. No? If so, his restraints must be inconspicuous and his dinner tray, all the food in it, and his tablet must all be glued/bolted/strapped down too. Maybe that's a stunt guy filling in for Gary Lockwood? Anyone?

This gives me a reason to fight for my life all because of its beauty. Through Kubrick You Can See God
-
And of course the Gayane Suite soundtrack gives the scene a melancholic feel, really evoking the loneliness and remoteness of space.
-
His run cycle looks like he is stepping downhill at times, presumably when he is not perfectly keeping up with the room's rotation. Especially when the close up cam crowds him from the bottom. 1:00
-
I think it was captured in a rotating cylindrical room with a camera fixed to the central axis and objects fixed on the side of the cylinder.

Our concave earth. A Stan Kubrick foreshadow.

Also, if you run around like the guy on the video above, going one way will make you feel heavier. Going the other way will make you feel lighter. And if your running(against the spin) speed matches the spin speed, then you will feel weightless, and float!! until you hit a chair that is attached to the cylinder and is spinning with it.. then the chair will exert force on you (which will hurt), and make you rotate again.. thus making you "fall down"
-
If a ball is placed in the center it will stay there if its relative velocity to the cylinder is exactly 0m/s perpendicular to the spin axis. If you "dropped" it from there, it would be the same as pushing the basketball in space. So it would just go in the direction you pushed it. BUT since the cylinder is spinning, and if you were on the inside, the ball would seem to you as if it spinning around the cylinder spin axis as it slowly got closer to the inner surface.
