In the diagram at 4 minutes 30 seconds, the labels for h_1 and h_2 are mixed up. Sorry about that!

Everything I am talking about here is standard material of undergrad physics textbooks. My personal favorite is good old Goldstein https://en.wikipedia.org/wiki/Classical_Mechanics_(Goldstein)

On variational principles more specifically I quite like this textbook: https://link.springer.com/book/10.1007/978-0-387-37748-3
