AP Physics 1 Units
All eight units of the AP Physics 1 course framework, with approximate exam weighting and topic counts. The 2024 redesign reorganized rotational content across two units (Torque and Rotational Dynamics, then Energy and Momentum of Rotating Systems) and added Fluids as a new tested unit. Approximate weightings are from the College Board Course and Exam Description (see also the formula sheet); exact weightings vary year to year.
2
Force and Translational Dynamics
Newton's three laws, systems and center of mass, free-body diagrams, gravity, friction, springs, and circular motion.

The whole course.
Everything above, mixed together. Work the whole-course challenge deck, sit an exam-length cumulative whose 42 questions mirror the real section's unit weighting, or blast every unit's misconceptions in the arcade.
Your mock exams
All eight units are fully built: every unit has its topic hubs, worked lessons, misconception diagnostics, targeted drills, interactive applets, and a cumulative MCQ exam.
