Nice idea. I like it some, but not completely. I love that they use biology and biomechanics to develop and give context and meaning to the physics, but would like to see a better quality, truer epistemology and philosophy of science in it.
On the website for the book, they say:
“Body Physics sticks to the basic functioning of the human body, from motion to metabolism, as a common theme through which fundamental physics topics are introduced.
Body Physics was designed to meet the objectives of a one-term high school or [a college] freshman level course in physical science, typically designed to provide non-science majors and undeclared students with exposure to the most basic principles in physics while fulfilling a science-with-lab core requirement. The content level is aimed at students taking their first college science course, whether or not they are planning to major in science. However, with minor supplementation by other resources, such as OpenStax College Physics, this textbook could easily be used as the primary resource in 200-level introductory courses.
