کتاب مرجع: Fundamentals of Physics

Halliday-Resnick-Krane’s “Fundamentals of Physics” is the standard undergraduate physics textbook in most Iranian universities. This series follows Halliday’s chapter and section outline — definitions, core concepts, and key formulas — with independent Persian and English explanations and additional parallel problems for each section.

The intent is that students can read Halliday as the primary reference and find explanations, worked examples, and further practice here. Per copyright rules, no text, figures, or problems from the book are reproduced; Halliday chapter/section numbers are cited only as pointers for parallel reading.
