Hi friends, "Engineering Physics" is an essential subject in the first year of a Bachelor of Technology (B.Tech) program. It aims to provide students with a comprehensive understanding of the fundamental principles of physics and their applications in engineering. The course covers a broad range of topics, including classical mechanics, thermodynamics, electromagnetism, and waves. It introduces students to the fundamental principles of physics, such as motion, force, energy, and momentum, which are essential for understanding the physical phenomena underlying various engineering applications.
The course also covers topics such as wave optics, particle physics, and relativity, which are critical for understanding the principles behind many modern technologies, including lasers, fiber optics, and nuclear power.
The subject helps students develop problem-solving skills and enables them to apply physics concepts and techniques to real-world engineering problems. By the end of the course, students will have gained a solid foundation in physics, which will be useful in their future studies and careers in various fields of engineering, such as mechanical, electrical, and civil engineering.
On this thread, I am sharing handwritten lecture notes for PHYSICS for First Year Engineering Students. This is a handwritten note given in class by the professor and will help you prepare for your semester exam. The course for most universities will be covered in these notes and will give you a crisp understanding of the various concepts.
