Before entering the university I studied the book "University Physics with Modern Physics" (written by Young and Freedman). In that time I used to study physical problems with methods taught by that book.
Now I'm math student at a university and I'd like to study a mathematical model of Classical Physics and solve some physical problems using this model. For example: I would like a model in which I can formalize and prove that the electrical potential energy inside a hollow charged spherical condutor is constant and I also want to formalize and find, in this model, the electrical field along the x-axis from a uniformly charged disk.
I'm only interested in models of Classical Mechanics (maybe using Symplectic or Poisson Geometry) and Maxwell's electromagnetism.
My question is: which book or article teaches a good mathematical model of Classical Physics? Please give some references.
The following PDF show more or less what I'm looking for: Notes on Mathematical Physics for Mathematicians (written by Daniel V. Tausk).
If you know one model, please, show how to formalize in this model one of the two examples I wrote before.
Thank you for your attention!
