For those starting in physics, it's crucial to identify specific areas of interest, such as relativity, classical mechanics, or quantum physics, as each has different depth and complexity. For beginners without a strong mathematical background, "Conceptual Physics" by P. Hewitt is recommended, along with his online lectures available on YouTube. As foundational knowledge is built, transitioning to a general physics textbook like "University Physics" by Young and Freedman or "Fundamentals of Physics" by Resnick is advisable. For advanced learners, Feynman's lectures are a valuable resource. Additionally, free resources like LightandMatter.com and Khan Academy provide accessible materials, while MIT's OpenCourseWare offers comprehensive lectures for further study.
