General Physics

Exam Answer Key

Course Introduction

General Physics is an introductory course that covers the fundamental principles of classical physics, including mechanics, heat, sound, electricity, magnetism, optics, and basic concepts of modern physics. Designed for science and engineering majors, the course emphasizes understanding the laws of nature through problem-solving, experimentation, and the application of mathematical models. Students will develop analytical and critical thinking skills as they explore topics such as motion, forces, energy, waves, thermodynamics, electromagnetism, and the behavior of light, providing a solid foundation for further studies in physics and related disciplines.
