Understanding Physics - Third Edition

Viac o knihe

This thoroughly revised third edition offers a comprehensive introduction to college-level physics, tailored for today's students. It covers essential material for an introductory course in a clear and engaging manner. The authors, recognized experts in the field, provide insights into the physical universe and the mathematical tools used in physics. Each topic is introduced from first principles, making it accessible for students without prior physics background while also facilitating progression to advanced courses. Notably, relativity and quantum mechanics are introduced earlier than typically found in introductory texts and are integrated with classical material. The book includes worked examples and links to over 600 problems and solutions, as well as interactive problems, simulations, and videos accessible via URLs and micro QR codes. This edition features a revised approach to electromagnetism, emphasizing the relationship between microscopic and macroscopic perspectives. It serves as a foundational course for undergraduate students in physics, materials science, and engineering, and has been updated to align with the revised definitions of SI base units effective May 2019. Ideal for first-year physics students, this edition combines a solid foundation with interactive resources.
