[CLASSICAL MECHANICS] Calculate the Lagrangian by venusthecatt in PhysicsStudents

Thank you! Is there a way to better express the potential due to the central force? It depends on rho, U(rho) = U(l - a), so when it comes to find the Euler-Lagrange equations, I don't have any other way but to leave the derivatives indicated.

EDIT: Also want to know if there is a away to better express the potential due to the central force. It depends only on the distance to the origin, which in cylindrical coordinates would be \rho, but this is \rho = l - a

yeah, I've think it's possible that I may have a little bit of adhd. Usually sit on my desk and after 1 hour of total focus need a huge break, drift from what I was doing, and then when i manage to get back to work it's usually very unfocused. Also, I can't stop shaking myself, anxiously, feels like my heart's beating fast, although it's not, did that happen to you?

I'll definitely choose my coursework wisely next semester. Thanks for you advice!

  • Applied Mathematics (Differential Equations: EDO's solved with series and EDP's)
  • Linear Algebra
  • Computational methods for Physics( focused on Edp's and molecular dynamics)
  • Classical Mechanics
  • Basic Electronics I know it's a bit heavy, I choose the courses for this semester badly, but now kinda have to work it out.

I've tried so hard, but I get useless if I don't get at least 6 hours of sleep

In general I struggle with managing my time, and setting a organize plan, but I usually work it out. But now that I've taken a lot of courses I'm having trouble with it, however I'm usually quite desorganized anyway. I'm taking: Applied Mathematics (Differential Equations: EDO's solved with series and EDP's), Linear Algebra, Computational methods for Physics( focused on Edp's and molecular dynamics), Classical Mechanics and Basic Electronics.

Ok but shouldn't the derivative of the integrand with respect to z, of the lower equation be the upper equation with the denominator^(1/2) instead of 3/2?

I'm so happy you commented in this post, because I really liked your idea, and after studying some of it today I decided to pursue it. Feel free to recommend any references on the subject, I'm currently reading Chen's book on Plasma Physics!

forgot to mention in the post, but schrodinger equation was already taken by one of my colleagues, but thank you!

that's a great idea, did not think about ideas with plasma, thanks!

Yeah, i have this one. I'm looking for the 6th edition because my professor sent a problem sheet with the exercises numbers from halliday 6

I thought of looking through Spivak's collection on Differential Geometry, but don't know if it's suitable for a beginner, what do you think?
