College Physics by Various Authors (2020): OpenStax.
College Physics meets standard scope and sequence requirements for a two-semester introductory algebra-based physics course. The text is grounded in real-world examples to help students grasp fundamental physics concepts. It requires knowledge of algebra and some trigonometry, but not calculus. College Physics includes learning objectives, concept questions, links to labs and simulations, and ample practice opportunities for traditional physics application problems.
University Physics by Various Authors (2020): OpenStax.
University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity and magnetism, and Volume 3 covers optics and modern physics. This textbook emphasizes connections between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result.
Conceptual Physics by Benjamin Crowell (2019): GNU.
For a semester-length course, all seven chapters can be covered. For a shorter course, the book is designed so that chapters 1, 2, and 5 are the only ones that are required for continuity; any of the others can be included or omitted at the instructor’s discretion, with the only constraint being that chapter 6 requires chapter 4.
Motion Mountain: The Adventure of Physics - Vol. I: Fall, Flow, and Heat by Christoph Schiller (1990-2020):
This popular book is downloaded over 40 000 times per year. If you are between the age of 16 and 106 and want to understand nature, you will enjoy it! The book promises wonder and thrill on every page: it tells the various puzzles about the colour of the bear and about the picture on the wall, explains about the many types of water waves, introduces the art of laying rope, tells about the dangers of aeroplane toilets, explores the jumping height of different animals, presents the surprising motion of moguls on skiing slopes, explains why ultrasound imaging is not safe for a foetus, gives the ideal shape of skateboard half-pipes and estimates the total length of all capillaries in the human body.
