AP® Physics 1, one force at a time.
Built on the 2024-25 course framework, in its order: eight units, each topic taught from scratch, with the math you need placed just before it is used. Then practice that checks what the exam checks: free-body diagrams, graphs, units and justifications that name the condition.

What the course covers
8 units and 43 topics in the order of the 2024-25 course framework, plus 5 math topics placed where they are first needed. Each topic has an interactive lesson, a free notes page and exam-style practice, and each unit a printable unit sheet.
747 practice questions, many in stimulus sets of four or five that share one table, graph or experiment, as on the real exam. Every option has its own explanation.
All 48 topics are built, each with its lesson, notes and questions.
How to use it
- Read the lesson. It checks what you need first, then walks the cause and effect one step at a time, with a picture for every process.
- Answer as you go. Anything you miss goes into your review queue and comes back when you are about to forget it.
- Train the hard parts. Free-body diagrams, energy bar charts, motion graphs and lab design, each checked step by step.
- Check your mastery. Your dashboard shows it by unit, topic and science practice, and every miss links to its lesson.
Ten trainers for what the exam marks hardest.
Drag forces onto a real scene and get each one graded, drive a cart and watch its graphs draw, build energy and momentum bar charts, design a lab, then answer the questions about what you did. The motion graphs and free-body diagrams trainers are free.
