Calculus-Based Physics II Exam Review

Course Introduction

Calculus-Based Physics II is a continuation of introductory university physics, focusing on electricity, magnetism, optics, and selected modern physics topics. Students explore electric and magnetic fields, Coulomb's law, Gauss's law, Faradays law, and electromagnetic induction, applying calculus to solve complex quantitative problems. The course emphasizes conceptual understanding and analytical reasoning through laboratory experiments and theoretical analysis, providing a strong foundation for further studies in physics, engineering, and related disciplines.
