1
Kinematics
Position, velocity, and acceleration in one and two dimensions. Vectors and scalars, motion graphs, frames of reference, projectile motion.
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; exact weightings vary year to year.

Force and Translational Dynamics
Newton's three laws, systems and center of mass, free-body diagrams, gravity, friction, springs, and circular motion.
3
Work, Energy, and Power
Translational kinetic energy, work, gravitational and elastic potential energy, conservation of energy, and power.
4
Linear Momentum
Impulse, momentum, and conservation in collisions and explosions.
5
Torque and Rotational Dynamics
Angular kinematics, torque, rotational inertia, and the rotational analog of Newton's second law.
6
Energy and Momentum of Rotating Systems
Rotational kinetic energy and conservation of angular momentum.
7
Oscillations
Simple harmonic motion for springs and pendulums, period and frequency.
8
Fluids
Density, pressure, buoyancy, continuity, and Bernoulli's equation. New to AP Physics 1 in the 2024 redesign.
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.
