Euler-Lagrange Equations for Beginners - Block on a Slope

Physics Ninja revisits the block on an inclined plane physics problem using Lagrangian Mechanics. The problem is first solved using Newton's laws of motion and then using the Euler Lagrange Equations with constraints.

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

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!

Thank you so much for giving us in depth knowledge

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?

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.

Very well explained, thanks a bazillion!

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

[MechEnginer]

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

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.

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

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

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.
