Lagrange Gleichung 1.Art - Beispielrechnung, Zwangskräfte berechnen (Teil 2)

Link to the playlist - Classical Mechanics: 🔗   • Klassische Mechanik   In this video, I'll explain an example calculation of Lagrange's equation of the first kind as simply as possible. The Lagrange formalism is an alternative formulation of classical mechanics and has significant advantages over Newtonian mechanics in many cases. In this video, we'll consider a particle that can move along a helical path. We'll try to find and solve the equations of motion for this particle and calculate the constraint forces acting on it.

For starting a physics degree, these two textbooks are standard reading. I was personally very satisfied with the second book in the series on electricity and optics, and I still often use it to look up certain topics. I only got the first book on I bought it at the end of the first semester, so I haven't used it that often, but it was very helpful for exam preparation on certain topics! The books are also suitable for preparing for university before starting your studies, especially since there are exercises at the end of each chapter, and the solutions to these exercises are also in the back of the book. (I would probably skip the first chapter of the book *Experimental Physics 1*.) ▶︎ Experimental Physics 1: Mechanics & Heat by Wolfgang Demtröder Amazon link: https://amzn.to/3DQBADP ▶︎ Experimental Physics 2: Electricity and Optics by Wolfgang Demtröder Amazon link: https://amzn.to/3DYgnaX After the first year of university, you continue with advanced courses in Theoretical Mechanics, Quantum Mechanics, and Electrodynamics & Statistical Physics (Thermodynamics). My book recommendations on these topics are partly in German and partly in English. This is because sooner or later (at the latest in the Master's program) all lectures will be in English. The course will be held in English. I've also had very good experiences with all of these books myself! ▶︎ Classical Mechanics by John R. Taylor Amazon Link: https://amzn.to/3r5Eixw ▶︎ Modern Quantum Mechanics by J.J. Sakurai Amazon Link: https://amzn.to/3UFvJa9 I primarily used this book for my first quantum mechanics course and was very satisfied. ▶︎ Introduction to Quantum Mechanics by David J. Griffiths Amazon Link: https://amzn.to/3BMZc9w As an alternative to Sakurai's book, I also ordered this one and can definitely recommend it. It covers all the important topics, but I would personally lean towards the other option. ▶︎ Introduction to Electrodynamics by David J.
