Course Introduction
Engineering Physics is an interdisciplinary course that combines the principles of physics with engineering applications to solve complex real-world problems. The course delves into fundamental topics such as mechanics, thermodynamics, electromagnetism, optics, and modern physics, while also introducing concepts in materials science and electronics. Students learn to apply mathematical models and experimental techniques to analyze and design systems relevant to various engineering fields. Emphasis is placed on developing problem-solving skills, critical thinking, and understanding the scientific basis of modern technology, preparing students for advanced study or careers in engineering, research, and innovation.
