General Physics I Question Bank

Course Introduction

General Physics I provides an introduction to the fundamental principles of classical physics, emphasizing mechanics, wave motion, and thermodynamics. The course covers topics including Newtons laws of motion, work and energy, momentum, rotational dynamics, gravitation, and simple harmonic motion, as well as basic concepts of temperature, heat, and the laws of thermodynamics. Designed for science and engineering majors, the course integrates conceptual understanding with problem-solving skills, laying a strong foundation for advanced study in physics and related fields. Laboratory sessions, if included, reinforce theoretical concepts through hands-on experiments and data analysis.
