Which marble will finish first?

While there are some excellent videos on this channel this is one of the weakest. I turned it off after the last place marble inexplicably came zooming down the staircase.

[@blacktigershearthstoneadve6905]

The author played with physics models for his own fun and eventually decided to cook some video out of it, god knows why. In the end mentioned chaos to justify empty content. Yes, we know that math models for marbles quickly become too complex and appear to be random, thank you. Don't get me wrong, it is a good channel, but I guess after 10 years Eugeny kinda tired of this work. Not his fault, it always happens eventually.

[@ExternusArmy]

@@jong7513 I think the stepped ones make mathematical sense given the more the steps are divided, the closer they become to a smooth line. Assuming they all have the same coefficient of restitution, the more subdivided the stairs become, the shorter the distance becomes and the position derivative begins to point down and to the right instead of individually right and then individually down.

[@romrom83]

1:05 Im weirded out by this one, how could the one with the most velocity take more time to go across the bump than the middle one?

[@official-obama]

1: it is a lot higher up, so it has to roll for more time 2: it smacks much harder

[@acidicjello1962]

This is a good question. By observing the yellow and blue tracks, it appears that the yellow marble hits the track after the initial bounce farther along the hump than the blue one does, or at least has fewer bounces on the uphill slope. This means there are more impacts slowing the blue marble's forward velocity and forward rotation. The fact that its velocity becomes so low by the time it reaches the top of the hump means that it spends a lot of time up there before it can pick up speed again. This is just an observation and not an explanation. The more fundamental question is why does that initial bounce favor the forward direction more for the yellow marble than the blue one. Would it be different if rolling wasn't a factor? Would the blue marble beat the yellow one from some higher distance? Yes it "smacks harder" but what is the reason that the smack takes more forward velocity away than the extra velocity it started with? I don't know and now I am invested...

Thanks for the interesting video. But it was not what I expected, which was that it would be about the brachistochrone curve. Maybe there could be a follow up with some physics explanation?
