False! Coriolis might be a thing if spin was the only motion. You must do a vector analysis of all motions, to get the resultant vector of the combined effect of all motions. We can debunk the globe by doing this for just 2 motions: spin + orbit + 21 mm/s/s alternating accel/decel every 12 hours or half revolution, experienced by everything on earth's surface, where is it? Nowhere! A rock balancing statue proves motionless earth. Rigid body rotation with translation is the physics kzbin.info/www/bejne/d5eok6akhL2ljpI Note the word "rigid" because only solid bodies can spin like a top see flat.wtf [ flatearthclassroom.blogspot.com/2020/11/centrifugal-force-based-on-rotation-axis-of-body.html ] And that's the end of the glob!

What we feel as the force of gravity is a something of a Coriolis effect. It derives from the conservation of all objects' constant velocity thru spacetime, and the way mass slows time with increased proximity to the center of mass. The upper part of an object, farther from a nearby mass than the lower part, and so moving thru time faster than the lower, is "pushed" toward the lower part, causing what seems to be motion toward the center of the nearby mass, in much the same way that a projectile aimed toward the pole of a planet seems to trace a curved path.

[@alepunto7404]

@@orbismworldbuilding8428 Yes, you are right, it´s better to think in 4D. I guessed that shape could affect gravity because a stick perpendicular to earth would have greater time dilation differential between both ends of the stick than a stick parallel to earth, hence the perpendicular stick should feel more gravity. But I was thinking in 3D. I guess that taking in consideration time as another dimension of the object, the bottom of the object with slower "time speed" its going to slow down the upper part of the object with higher "time speed". And decreasing the "time speed" of the whole object, increases the "space speed", causing the object to start moving towards the earth.

The Corillis force would be a good way to simply prove that the Earth is a sphere (not quite perfect, but very close to a sphere) and not a disc. You would have to do the experiment with the Folcault pendulum at 3 different locations that are not on a line. In the spherical model, you could use this pendulum to determine the latitude you are standing on. A rigid disc cannot rotate in such a way that the same values as with the sphere would come out.

[@kristoferkrus]

Good visual explanation! However, the fact that the astronaut's feet move faster than his head does not make him feel the Coriolis effect and consequently feel the spin, as the Coriolis force only comes into play when something is moving relative to the rotating reference frame, and the astronaut in the example is still stationary in the rotating reference frame. On the other hand, he would feel the spin if he was moving around inside of the rotating system, but then he would feel it regardless of how much faster his feet were spinning than his head.

[@miladestesnai9650]

What if the circle has small radius? It is understandable that angular speed will be the same anywhere in the circle, but the linear speed will be greater at the feet. Will that difference in speed make astronaut feel the differences in that linear speed? And if astronaut feels the difference in linear speed does it mean he/she feels the force?

[@kristoferkrus]

@@miladestesnai9650 In order for the astronaut to feel a certain thing, that thing has to be measurable. How do you measure a difference in velocity? I’m not sure how you would do that in the general case. However, if he moves around, which he is likely to do at some point, he will notice that he doesn’t move as he is used to moving when affected by normal gravity on Earth, and measuring this deviation in how he moves (which could be done by some visual tracking system, for example) is a way to measure the Coriolis effect. I’m pretty sure he would feel this deviation unless the rotating wheel was huge or he was moving very, very slowly, even if he wouldn’t be able to put his finger on exactly what was different. Another effect, which would be measurable even if you remained perfectly still relative to the rotating reference frame, is the deviation in acceleration which causes the artificial gravity. Since the acceleration is proportional to the position relative to the center of rotation (if we assume a 2D system), you will feel that your limbs become heavier the closer to the floor you keep them, and on the contrary, if you for example raise up your arm, it becomes lighter. And your arms will not be pulled what you normally think of as straight down by the artificially gravity, but slightly outwards from your body. But these are effects of the centrifugal force and not of the Coriolis force.

I feel like calling these forces "fictitious" is misleading or at least unnecessarily confusing. As explained in the video, these forces are *observed* due to the frame of reference. Calling them fictitious and invented implies they're not real in any capacity, but their effects are plain to see. I think calling them "observed" or "apparent" forces or some similar term without the dismissive connotation would help a lot. Having finished the video the kinds of terms I described are used after the initial explanation, which I appreciate.

[@ScienceClicEN]

I would be tempted to say that they are fictitious in the sense that they are absolutely undetectable locally (with an accelerometer for example). They are only "detectable" in the sense that they make straight lines look bent in certain coordinate systems. But in the more modern and powerful framework of general relativity these forces don't exist at all. On the other hand I agree with you that the terms "observed" or "apparent" might be better suited. I especially like "apparent" as it really conveys the idea that they are almost an "optical illusion".

[@blinded6502]

It's kinda like saying that being in a moving train means that ground fictitiously moving relative to you.

Is this not very similar to general / special relativity ?! Looking at the centrifuge and how the ball goes forward when looking from outside but down when the point of reference is holding the ball

[@narfwhals7843]

It is very similar. The coriolis and centrifugal forces are pseudo forces that arise from viewing inertially moving things from a rotating (that is non-inertial) reference frame. In general relativity, the force that makes things fall is _exactly the same thing_ . Standing on the surface of earth we are non-inertial observers while freely falling objects are the inertial ones. We see a force pulling them down(like the coriolis force pulls things sideways) but it vanishes in free fall.

[@aminuolawale1843]

Cool stuff! I was writing a story where in one of the scenes, astronauts are travelling in an elevator up the shaft of a massive centrifuge very rapidly. I imagined the Coriolis effect would manifest and ended up making the astronauts feel a push in the opposite direction of the centrifuge's rotation (if the astronauts didn't hold on to anything, they would tilt sideways as the elevator ascended). It's a bit more exaggerated than it would be in real life but I imagined that was what would happen in such a scenario.

[@Snort70]

I've always thought that a centrifuge isn't the best way to make artificial gravity of this type, since of all the issues with construction combined with the issue of Coriolis effect. Instead, I imagine two spaceships bound by a cable, spinning around the center of the cable, like two people with their arms outstretched. That way, both ships would feel a centrifugal force, and the cable could be made long enough to make the Coriolis effect negligible. Also, this method doesn't require any additional construction on a spaceship, as all it needs is a place to attach the cable, and spacecraft are usually designed to be able to withstand 1g of acceleration.

[@AndiAbrudan]

The problem with your approach is there's going to be much less usable space. Due to nausea, you're always going to have a bit of waste space in the centrifuge, but you get more "real estate" for the same amount of angular speed than you would get in 2 ships tied together. I agree that this idea is much better suited for early space travel, as the initial cost and maintenance are probably lower, but the centrifuge is the best bang for your buck

[@Snort70]

@@AndiAbrudan I agree that you will have less usable space. However it’s essentially impossible to launch a Centrifuge on its own, meaning you’d probably have to assemble it in space, driving up the cost a lot. For this reason, I believe my method has more bang for your buck. Because in order to have a centrifuge of a large enough size that it’s possible to stand up without severe nausea, you would need several spaceships worth of material. Also, available space isn’t usually a concern for astronauts. Apollo astronauts spent weeks crammed into a space the size of a minivan. But yes, in the far future, large full centrifuges may become the norm. However I also want to mention that both designs are centrifuges. It’s just that my design only uses 1% of the edge of the centrifuge, the rest is just empty space. This means you can have a higher radius to space ratio, helping prevent that sort of force.

Much more important for the lift of planes is the speed by which it moves through the air. How the air is moving over the ground below is irrelevant for the plane, which is why speeds for aircrafts are normally in knots. Knots already specifies that the speed is measured compared to the air or the water something travels to instead of compared to the ground. Since the air through which the plane travels already experiences the coriolis effect itself, I think it becomes irrelevant as far as planes are concerned. It does matter for navigation, though. A plane flying straight from north to south has to fly in an arc to actually get where it wants to.

This is the best video on Coriolis. I wonder why isn’t it at the top of the subject “Coriolis.”

Very nice and instructive video. Many thanks.

Thank you 😊, you never fail to teach me something new. Now I have to watch this a few more times to fully digest all the material. This was super fun to learn and I was bestowed great knowledge. 👍

The animations on this channel are always so useful

[@AjayYadav-zq4nv]

Amazing......This is called the genuine explanation.

The 'eotvos effect' is so cool!

[@rongarza9488]

Great video. Slight correction: Further involves time; farther involves distance.

This is the best science video I've seen in months, maybe years.

[@paulkramer5566]

Very clear explanation of fictituous forces. Thank you

[@betting55555]

This video is so well done. really good explanation, thank you

[@ScienceClicEN]

Glad you liked it!

[@david0hinckley]

Great explanation, the conservation of motion and inertia made it click for me. What an educational KZbin rabbit trail :)

FINALLY, I understand why things work the way they do in a spinning space wheel a la "2001", etc. It just never made sense to me until you explained the Coriolis effect. My senses just told me everything should just be free floating. I guess that means that if the wheel wasn't spinning around it's axis, there would not be a Coriolis effect and everything would just float freely like it does in the ISS.

Whenever I hear that music I get all excited because I know I'm going to learn something really really incredible from you. Thank you for teaching everybody your knowledge. I for one thank you from the bottom of my heart ❤ .

*Very clear presentation👌👌*

[@TravisLee33]

Really good explanation

[@AyushYadav-st4kr]

Great explanation Thanks❤

Truly a great channel!

Very simple for people to understand. When they taught us about Coriolis force back in those days, we hardly understood what they were talking about. We had no computers nor internet.
