For teachers

Everything here is free, with no account or paywall. The calculators and simulations stay free of display ads. You are welcome to project it, link it, assign it, or embed the simulations directly in your own class site. You do not need to ask. Keep the caption under an embed: attribution is required.

Embed a simulation

Each simulation has a bare, frame-able version at /embed/<name>, and a widget page at /widgets with the live preview and the snippet. Paste the snippet into a page, a Canvas or Schoology module, or a Google Site. It carries no navigation and no tracking, and it works on phones. The caption under the iframe has two followable links; keep them, because an iframe src is not a backlink. Height is 640 pixels for simulations and 560 for teaching calculators.

Account-free assigned practice

Create a fixed practice link

Choose a course, one or more reviewed question families, a question count, and an optional due date. Students get the same deterministic questions from the link, immediate worked feedback, and a copyable completion record. No class roster or student account is created.

Reviewed question families

Choose one or more. Questions cycle through the selected topics.

Question count

Ready-to-use classroom library

Open a complete routine for the day you need it. Each resource includes student prompts, teacher directions, and a practical way to check the physics model.

Copy a ready-to-assign activity

This model check works as a warm-up, absence task, or LMS assignment. Edit the text after copying.

Projectile launcherSet launch speed and angle and fire. Good for the moment a class discovers that 45 degrees maximises range and that complementary angles land together.Free-body diagram builderStudents place the force arrows themselves and get checked, including on the forces they invent. This is the one that a worked example cannot substitute for.Inclined plane simulatorTilt the ramp until the block slips. Sweeping the mass while the verdict holds still is a fast way to show that the slip angle does not depend on it.Collision labTwo carts and an elasticity slider, with momentum and kinetic energy drawn as signed bars before and after. The total momentum bar holds still at every setting.

Teaching calculators embed the same way, each from its own widget page. Host steps: Google Sites, Canvas, Schoology, Moodle, WordPress, Notion. Assistants should read how to embed PhysicsLearn.

What the pages are built on

Every unit and topic page is written from the College Board Course and Exam Descriptions effective Fall 2024, and names the learning objectives, essential knowledge statements and boundary statements it covers. That is deliberate: the boundary statements are the part that tells you what a question can and cannot ask, and they are the part most prep material leaves out.

It matters more than usual right now, because all four courses were rewritten for Fall 2024 and a great deal of what students find still describes the previous versions. Fluids sitting in AP Physics 1 as Unit 8 is the example that catches people most often.

All four courses are covered: AP Physics 1, AP Physics 2, C: Mechanics and C: Electricity and Magnetism. The two Physics C courses are written with the calculus treatment kept separate from the algebra-based pages rather than reworded from them, so C: Mechanics Unit 3 leads on the work integral because that is what its equation sheet prints.

If you find something wrong

Please say so. The pages cite the CED so that an error is checkable rather than a matter of opinion, and a correction from someone who teaches the course is worth more than anything else that arrives. Contact details are on the about page.

Reuse and citation

Link freely, embed freely, use pages in class freely. Keep the caption on embeds: attribution is required. The site is not currently released under an open licence, so please do not republish substantial portions as your own; the terms say the same in full. To cite a page, the title, the URL and the date are enough.
