Euler-Lagrange Equations for Beginners - Block on a Slope

[@CD_Yujin]

Helpful and easy to understand for beginners because of the detailed step-by-step solution. Thank you!

[@PhysicsNinja]

Thank you!

[@refathbari5690]

Wow, this is literally undergrad-level physics content, thank you! An old video you did on the field of magnetized sphere was also amazing. Keep it up!

[@Googleeknowledge1111]

Thank you so much for giving us in depth knowledge

[@kirokamui]

Very well explained , thanks a bazillion!

[@tcf70tyrannosapiensbonsai]

Exactly what I was looking for. Em, unless a few speed measurements at a few locations during the fall would have been great, but thanks anyway, Jonin-San.

[@Woodsford123]

Great explanation. Thanks!

[@PhysicsNinja]

Glad it was helpful!

Pretty cool! Happy new year🎉🎉🎉

Are you allowed to make the connection that your motion in the y direction is -tan(theta)x and just replace all your y's in the lagrangian with that and just have one lagrangian in x that when solved also gives you your y?

[@MechEngin3er26]

When you do the second derivative with respect to t is there not an implicit differentiation that occurs?

[@jean-francoisburdet4458]

What's your hardware / software setup to produce such videos ?

[@ChaineYTXF]

Very nice, but: Arrows missing on g and N to distinguish from scalars, norms and coordinates😢 Can be quite confusing for learners

[@thedigitaluniversity7428]

SUPERB!!

[@PhysicsNinja]

Thanks a lot!

So, the native German-speaking Swiss man - Euler has a surname that is Germanic. It is pronounced "oiler" like Houston Oilers. Please try to pronounce it in this manner. Thank you.

[@OMNIPHEAST]

It was so cringe

[@gravitystorm58]

Why is the acceleration in the y direction = 0? Isn’t it moving down

[@ethandrood]

The x-axis is parallel to the slope, so there is no motion in the y-direction relative to that coordinate choice. Tilt your head. Remember, motion is relative to the coordinate axes. When he rotates the axes, there is a y acceleration.

17:44 this y' is just a distance not a derivative right? I had to go back and watch that a couple of times because decades of teaching calculus I have made me associate y' with a derivative (I would have guessed it was dy/dx since your y dot is dy/dt).

[@kingplunger1]

"oiler" not uler ;)

[@kikilolo6771]

Are you sure ? I used to say "oiler" but I had a german math teacher who is also a sercher in combinatorics (don't know how to say it in english) who say "Euler" and so he must be able to say it the right way. (He also likes to invent poems on maths theorems in german like on on the strength of a point or the double ratios / hanarmonic ratios (don't know how to say it neither)

[@kikilolo6771]

Bruh I wrote this before watching the video and hearing the "u"ler

[@FrancisDavey]

@@kikilolo6771 Euler was Swiss German, and as far as I can see "oiler" is right, your German teacher was probably reading it as standard German

[@soyuzssr]

Euler is pronounced “OIL-er”

[@fra2025]

wowwwwwwwwwwwwwwwwww🤩🤩

[@marknandor784]

Please stop saying "Yooler." It hurts my ears. I'm not expecting you to be able to pronounce it properly, but PLEASE, at the very least, pronounce it "Oiler." It sounds to me like you're Canadian, so saying "Oiler" should be easy for you.

If this video was meant for beginners, it is a fail. You skipped alot of information. If this was for people who already knew it then yeah it is good.
