Designing the cycloid feet took the exact same amount of time to design the main cycloid.

Yup

Lol!

Yes

Thats like one of the most popular videos on his channel

Yessss, I just commented about it uwu

As long as you don't follow a tautochrone curve you will never be faster

Same I remember how he says brachistochrone

@@gustavgnoettgen Brachistochrone then. Tautochrone is used to refer different path length but giving the same time to get from A to B. Both are the same path but named differently depending on what you re looking for.

Go the Brachistochrone!!! Lol

As per this video , whether you knew it earlier than us and it is now that we are knowing it , we will still meet at the same point . Ik this comment makes no sense

@@kirkhamandy All you people? Really... So you take my random throw away comment made on KZfaq, and claim to know everything about my schooling. Along with magically having knowledge about my attention span whilst being taught. Oh and you know I’m forgetful too! That is more impressive that this video. Maybe you should get out more, relax and eat some pasta 🍝 I’m not sure if you are trying to make a genuine point or just wanting to be pedantic? Anyway it comes across as the latter. Take care, and enjoy your many hours of math. 😊

@@kirkhamandy Fair enough, I understand now. I did actually enjoy physics along with math, and my comment was meant jokingly. I can totally understand your stand point, as I have seen many similar examples regarding music production & songwriting. I’ve been a professional producer for many years now and see so many people praising so called producers, who cannot actually produce anything unless it’s done for them. I have to work under many different names when producing different genres, because of how people allocate one name with one genre. It’s messy and I could comment on many videos regarding this, but I don’t bother as it would probably come across wrong. I now only use my personal channel for fun projects, so nobody knows about everything I actually do, it’s easier. Anyway, thank you for clearing that up, and I would suggest to try not letting the comments on KZfaq impact on you, it’s mostly nonsensical babble. 😊

@@kirkhamandy No problem, all the best to you. 🙏🏼

Yeah

Tunisia, love you all.

You probably searched for something similar on Google and since Google and KZfaq are both connected, it could be that the KZfaq algorithm reacted to your Google search (if you're logged into KZfaq with your gmail account).

Gravity curves space...

Well actually the path in general relativity that is the fastest is still straight. It just differs from how our intuition of straight paths works for euclidean space. Technically, all objects in free fall are on straight paths. Whether that's the earth around the sun, a ball through the air, or a satellite in orbit of earth.

@@solsystem1342 What's going on here is that the path and pace of the rolling object is a *derivative* of gravity and the form of the ramp, not a straight line (in terms of gravitationally-reshaped spacetime). But it's still intriguing to look at it in those terms. How might one characterize the path of the ball through spacetime? If gravity-"bent" space were "straightened out" might it become a straight line? Some other definable curve? I myself lack the wherewithal to understand it fully much less to express it mathematically -- but I think the intuition of @Hyperscience has merit. We live in a deep gravity-well. Our universe is invisibly skewed.

@@jamesg1367 oh, no. I didn't mean a path on a ramp was a straight line in spacetime. Neither is standing still.

@@solsystem1342 In real terms yes, but I think for this purpose, mathematically and conceptually, one would assume Earth were at a standstill. I think that's consistent with Einstein's "man in a falling elevator" thought experiment. It would serve to isolate gravity as a factor in the shape of the object's path.

Technically the path of point A to B on Earth is still an arc, not a straight line, since it follows the (ground elevation) curvature of the Earth. Though it could be approximated as a tangent/straight line, since your change in angle towards the center of the Earth is less than 0.01 degrees if you travel under 5 miles distance. Not to nitpick your last sentence, but obviously as the video showed, going downhill (downhill = constant negative gradient) is slower than going down a parabolic slope which also happens to go up a parabolic slope in the last half. It's just converting potential energy faster to kinetic energy, which results in a fast velocity resulting in more distance traveled over time. m*g*h = PE = KE = 1/2mv^2, where PE=100% at the top height, and KE=100% PE=0% at the bottom height.

@@APioneerInTheSeaOfStars Makes sense. The only other caveat is that a falling object would reach a given point faster due to less friction. So, are you a physicist?? 😄

@@Dozerson2 Anyone can be deemed a physicist, but I do not have a physics degree. Just a good ol' engineer that took a few physics courses. One point about what you said, "friction". Ideally, the ball going down a surface will be rolling along the surface, so friction really isn't that big of an issue. Search "rolling friction". There is very little friction, almost negligible, if a circular object rolls along a surface. There is no sliding friction on the ball. If you are talking about air friction, both balls rolling down a slope or falling through air will reach the same max speed over time because air friction becomes the dominant force stopping acceleration. It would reach "terminal velocity".

@@APioneerInTheSeaOfStars Good to know!

@Dozerson2 - And that downhill is a cycloid.

"comment no.88:" u a bot for sure

@@rahilrahman266 how?

Yeah, especially the bit with "the higher you start the lower the frequency" which is NOT what I was told in high school! Grr!

Not today sonny

@@RegebroRepairs Your teacher was making the assumption sin(theta) = theta, which is nearly correct for small angles.

You don't need that much of background knowledge to understand this...

@@aboriani well ig it just means I'm that dumb, ay?

You can watch 3b1b's video on it. He gives an elegant explanation to the brachistochrone problem. kzfaq.info/get/bejne/edKUY9NkxpqXlok.html

It is not just a coincidence that pi is roughly equal to the square root of g. An early idea for defining the meter was for it to be the length of the 2-second pendulum in the grandfather clock.

@Google-san sqrt = square root

@@xiaoshen194 oh man sorry bro🤣🤣

I think the cycloid is just used for reference

On the way up, the string comes in contact with the cycloid, which regulates the speed. Take a closer look, you can see it in action. I think probably if you didn't start it high enough to come in contact with the cycloid, it wouldn't have any effect.
