Fundamentals of Physics, Extended, 11th Edition

From the first measurements of length and time to quarks, leptons, and the Big Bang, Fundamentals of Physics, Extended builds a broad, connected course in physics. This 11th edition moves from mechanics and energy into thermodynamics, electricity and magnetism, optics, relativity, and modern physics, giving readers a structured route through the subject’s central ideas.

Start with motion, forces, and energy

The opening chapters develop the foundations: units and measurement, vectors, motion in one and several dimensions, Newton’s laws, work, energy, momentum, and rotation. Further chapters extend these tools to equilibrium, gravitation, fluids, oscillations, and wave behavior. The sequence helps place familiar physical phenomena within a consistent framework of concepts and quantitative reasoning.

From heat and fields to modern physics

The extended text continues through the laws of thermodynamics, electric fields and circuits, magnetism, electromagnetic waves, images, interference, and diffraction. Its later chapters address relativity, photons and matter waves, atoms, nuclear physics, energy from the nucleus, and particle physics—broadening the discussion from everyday mechanics to the behavior of matter and energy at smaller scales.

A course-text structure for working through the subject

Chapters are divided into focused sections and include review and summary material, questions, and problems. Appendices, answers to checkpoints and odd-numbered questions and problems, and an index support study and reference. That organization makes it possible to follow the book in sequence or return to a particular topic while reviewing a course.

Who may find it useful

This textbook is suited to readers following a broad general-physics course and to students revisiting foundational topics across mechanics, waves, fields, and modern physics. Its coverage also offers a substantial reference for readers who want to see how the major areas of physics fit together.
