That explains the motion of a Foucault pendulum at one of the poles but I have trouble understanding the motion and apparent procession when between a pole and the equator.
Very well made video... Could you kindly share the link of the app or whatever, for the part where you were just clicking on the globe and a pendulum was moving.
Its hard for me to understand how the pendulum swings in the same exact path and is unaffected by the spin of the base the pendulum is mounted on. How is the pendulums motion independent of the earths motion if it is mounted on the earth? I like this video because it clearly shows the pendulum swinging in a straight path while the base it is mounted on spins. It visually shows what I could not envision for the experiment when done for the earths rotation. However, I still can't understand or articulate WHY the pendulum swings straight while the base spins. I feel stupid.
Without googling GPS coordinates, I’m guessing you are near Seattle? My rationale is based on the fact that the 45th parallel runs through Lincoln city, just 18 miles north of where I live. It also runs through Salem, Oregon. I remember fondly going to the California Academy of sciences in Golden Gate park as a boy and patiently waiting for the pendulum to knock over a stick of chalk. Yours is the best video I have seen so far.
This video did convince me that the Foucault pendulum is a good device to observe Earth's rotation. But I'm still struggling with one aspect of it. The pivot is attached to a ceiling, (or a tripod in your case) which is connected to the rotating body. So how can the pendulum move independent of the rotating body?
I think that's one of the things that introduces friction, which eventually slow the pendulum. To avoid the line twisting as the earth rotates, something that is free to turn (like a swivel snap) would help. That said, the weight is free to spin as well, which could cancel any torsion.
relativistic part of movement was good, but question is if the top mechanism of hanging is freely rotating as the carousel or not, and then to me, earth isnt rotating along axis Y as the carousel but earth is tilting in angle to the pendulum so that complicates my imagination of the pendulum since the mechanism is made to allow rotating not tilting. earth was rotating along Y if it was 2d circle but since it is 3d ball it is rotating but in terms of angular tilting so that complicates the pendulum stuff.
The Merry-Go-Round pendulum ain't working for a multitude of reasons the first one being is the Earth does not stop and start this pendulum effect is a fallacy as the amount of variables that upset it generate distortions in its Ark.. .

@davidt5770 Machian principle. This demonstration can not prove whether the earth is spinning or the universe is spinning around us . Either way the same forces would be present.

@@Heracles_FE If the earth was not spinning, then the pendulum would not precess - its motion would remain constant. The motion of the universe around a fixed earth would not impart such a force to the pendulum.
@@doittoit00 It is called the Machian principle and is necessary for relativity , which isn't true, but you can't deny it and still believe in heliocentrism.
So typically, a focault pendulum is attached to the ceiling. So are we saying the floor beneath it is turning independently. That makes absolutely no sense. The earth doesn't turn underneath a hovering helicopter
With the merry go round, the tripod acts as the ceiling for the pendulum, if you look at the tripod is also rotating with the merry go round but the pendulum stays in the same plane
The pendulum is attached to the ceiling with something akin to a fishing swivel which allows the string attached to the bottom to rotate independently of the string attached to the top of the swivel.
Yes the Earth turns under the helicopter. You wouldn't notice it though for 2 reasons...it happens too slowly to see and the pilot uses his controls to maintain his position relative to the ground.
@AndySmith4501 it does, just like how the earth turns underneath a plane. If a plane is flying west, you're flying opposite the way the earth is rotating, so essentially your destination is coming towards you while you're in the air. For example, if you fly from Miami to San Diego (east to west), your flight will actually be a little shorter compared to your return flight from San Diego back to Miami (west to east), because on your return flight, you would be "chasing" your destination as it rotates away from you.
Putting that tripod on that merry-go-round was an excellent idea!! I've been trying to understand the Foucault pendulum for over a week!!
This is one of the basic principles of physics and math it should be shown to every grade school kid on earth. Nice work! 😊
One of the best examples of this Foucault Pendulum principle I have found on the internet - excellent.
This is an excellent video demonstrating how Foucault Pendulums work and how they disprove Flat/stationary earth.
random internet stranger at 11pm here: thank you for this video
Excellent explanation
And that is MUCH MUCH faster than the 15 degrees per hour (Thanks Bob).
Perfect presentation.😊
That's a brilliant demo.
I finally understand it. This explains it simply and clearly and also why it takes longer than 24 hours as you travel towards the equator
What an excellent explanation of the Foucault pendulum experiment. Hope Physics teachers find this.
Good explanation mister. Hot dog, I finally understand it.
Best video on the topic. Thank you.
Great demonstration!
Honestly best one so far that shows it's working clearly.
What an incredible video, thank you so much!
How clever an idea you have presented and I would hope science teachers use what you have demonstrated! Thanks for sharing and the best of luck!

A low friction universal type joint allows the pendulum to swing in any direction unimpeded.

The "pivot" should be a type of universal joint with the lowest possible friction.
Yes, I asked the same question. Would like to hear more on that topic. Comment here if you find some good answers for this
What is the purpose of the noise in the background? Does it make it eassier to hear what is being Said, or is it simply an annoying noise pollution?
Interesting

earth was rotating along Y if it was 2d circle but since it is 3d ball it is rotating but in terms of angular tilting so that complicates the pendulum stuff.
To see It in 3D you need vector calculus ...
The carousel Is a good example for a pendulum suxpended at a pole.

The Merry-Go-Round pendulum is only demonstrating the gyroscopic properties of the pendulum.
The rest of your comment is sheer stoopeedity.
@@bobadingo I don't understand what you mean...I am a science teacher and I would like to help...
Well, your globe is NOT a FLAT merry-go-round.
It effectively IS at the North and South Pole. Exactly what is being demonstrated here.
I think for an actual one to one relationship , you should have set the 'earth' in motion first.
"...I think..."
Bottom line kid is that no one in the real world CARES what an uneducated, no relevant employment fool like you "thinks".
It really burns you that you are irrelevant, doesn't it?
so the earth is a spinning disc,i dont thing so bub
So do you have an alternate explanation of the observation that a focault pendulum precesses?
@davidt5770 Machian principle. This demonstration can not prove whether the earth is spinning or the universe is spinning around us . Either way the same forces would be present.

You lost me when you said "descend down". Is the any other way to descend?
But a the pendulum is in the same Frame of reference as the earth. Does the earth turn underneath aircraft in flight?
Yes, Its the Coriolis effect. One has to take this into account when looking at trajectories of missiles and such.
Yes. It literally does
@@mrjohnson4970
So does the earth turn underneath aircraft in flight
What nonsense. Place the pendulum on the ball, spin it and then prove how it behaves!
School didn't go real well for you did it??
Your attention span is less than 2:50min?
It's going to react the exact same way
