In most physics courses the textbook is the course. Students read a chapter, work the problems at the end, and arrive at lab — if there is a lab — to confirm what the book already told them. We invert that order. In this course the bench comes first and the reading comes second. The text does not deliver the physics; it explains, deepens, and names what the student has already seen with their own hands.
That is why we say the reading sits underneath the bench, not in front of it. A student who has just watched a heavy ball and a light ball strike the floor at the same instant reads the free-fall section with a question already answered — and the chapter sharpens it. The reading lands because it has somewhere to land. Reading without that prior encounter is the thing students forget over the summer; reading anchored to an experience is the thing they keep. So everything below we recommend — we don’t require it. A family that runs the labs and reads two of these trade books slowly will get more from the year than one that grinds every chapter and never rolls a ball down a ramp.
The textbook is not the teacher. The bench is the teacher; the text is the reference you reach for afterward.
What follows is a short, deliberately curated list — not an exhaustive bibliography. Everything here is either free, optional, or chosen because it does something a textbook can’t.
Free core texts
You do not need to buy a textbook to run this course well. Two excellent, genuinely free options cover everything in the course map at full rigor.
- OpenStax College Physics 2e. A complete, peer-reviewed, college-introductory physics text, free to read online or download as PDF. Its depth matches the AP-level calibration of this pack, and its chapter structure maps cleanly onto our eight units — kinematics, dynamics and Newton's laws, circular motion and gravitation, energy and work, momentum and collisions, simple harmonic motion, torque and rotational motion, and fluids and pressure. This is our default reference text — when a lab note says “read more on projectile motion,” this is where to go. (OpenStax also publishes University Physics, a calculus-based version if a student is ready for the heavier math.)
- CK-12 Physics. A free, modular text pitched a notch more accessibly than OpenStax, with adjustable reading levels and built-in practice. Excellent for a first pass before stepping up to OpenStax on the same topic, or for a student who needs the concept in plainer language first.
Between these two, a family can run the entire year without spending a dollar on text. Start a struggling reader in CK-12, then move to OpenStax as confidence grows.
The optional textbook
For students aiming explicitly at the AP Physics exam or an honors-level college track, one paid option is worth considering — though it is genuinely optional.
- Giancoli, Physics: Principles with Applications, or Serway & Vuille, College Physics. Either is a standard college and AP reference — comprehensive, authoritative, full of worked problems. A used earlier edition costs a fraction of the current one and loses almost nothing for our purposes; the core physics has not changed. Buy one of these only if a student is AP-bound and wants a single deep problem-set reference to live with for two years. Otherwise the free texts above are entirely sufficient.
Trade books that bring physics alive
This is the part of the list we care about most. A textbook tells you what is true; these books show you how the truth was found — the false starts, the stubborn measurements, the human stakes. They are how a student comes to feel that physics is a living investigation rather than a settled catalog. Recommend one per semester as a slow read alongside the lab work.
- Thinking Physics — Lewis Carroll Epstein. Hundreds of physics puzzles that force you to reason rather than plug into a formula — each one a small experiment you run in your head. The single best companion to the kinematics and dynamics units — it builds the intuition a textbook assumes you already have.
- Six Easy Pieces — Richard Feynman. The six most accessible chapters from Feynman’s legendary lectures, on motion, energy, gravitation, and the behavior of matter, in the voice of the century’s great physics teacher. Perfect for the energy and gravitation units, and a natural bridge into the integration work.
- Two New Sciences (excerpts) — Galileo Galilei. The book that founded the science of motion, written as a dialogue — read the passages where Galileo rolls balls down an inclined plane and reasons his way to the law of falling bodies. The most historical book on this list, and a profound argument that physics is a human craft. Best for older students.
- Longitude — Dava Sobel. The story of John Harrison and the clock that solved the greatest measurement problem of its age — a vivid recreation of how careful timekeeping and stubborn engineering changed the world. It models exactly the measure-first curiosity this course is built to cultivate, and pairs naturally with the simple-harmonic-motion unit.
- The Way Things Work — David Macaulay (optional fifth). A gorgeously illustrated tour of the machines and mechanisms around us, from levers to turbines — a fine pairing with the torque, energy, and fluids units if a class wants a second, more visual book. (For an advanced reader, The Making of the Atomic Bomb by Richard Rhodes is a demanding but unforgettable optional history.)
Reference works
Finally, a couple of reference works earn their shelf space — things to keep open on the bench, not to read cover to cover.
- A good wall-mounted equations-and-constants chart — a large, clear reference sheet of the core formulas and constants (g, the kinematic equations, Newton's laws, the SI units) pinned above the bench is referenced constantly across all eight units. Cheap, durable, and far more useful in eyeshot than buried in a chapter.
- A units-and-conversions reference chart for the measurement and problem-solving work — a one-page guide to SI units, common conversions, and significant-figure rules, so a student can check their setup against a known-good reference.
- A reputable equipment-and-safety reference for every tool on the bench — not reading, but a habit: know how to use a stopwatch, a spring scale, or a motion sensor correctly before you trust its numbers.
Keep the list short and the books close. A family that reads two of these trade books slowly, anchored to real lab work, will finish the year with something a stack of chapters never delivers: the sense that physics is a thing people do, and that the student has now done a little of it.
