Interactive AP Physics Unit Reviews

Each review covers one AP unit in a single connected problem. You answer a question at each stage, the stage runs as a simulation, and a cyan ghost moves according to your answer beside the ideal solution. A wrong answer visibly separates from the real motion, and each common mistake gets its own explanation.

More units are being added. Teachers can share any review with a single link; students need no accounts, and progress saves in each student’s browser.

AP Physics 1

The flat curve stage: a ghost transporter moving too fast slides off the curve while the real transporter rounds it.

Unit 2Force and Translational DynamicsInteractive AP Physics 1 Unit 2 review: free-body diagrams, Newton’s laws, circular motion and orbits in one simulation. No account needed.

The coaster loop stage: a ghost cart with too much energy moves ahead of the real cart around the loop.

Unit 3Work, Energy, and PowerInteractive AP Physics 1 Unit 3 review: spring energy, conservation of energy, energy bar charts, friction, work and power on a roller coaster.

AP Physics C: Mechanics

The parachute return stage: a capsule falls with drag beside a height scale while a ghost capsule falls at the terminal speed the student entered.

Unit 2Force and Translational DynamicsInteractive AP Physics C: Mechanics Unit 2 review with calculus: time-varying forces, springs, drag and terminal speed, circular motion and orbits.

The camelback stage: the potential-energy graph and a ghost cart that turns back at the wrong position.

Unit 3Work, Energy, and PowerInteractive AP Physics C: Mechanics Unit 3 review with calculus: the work integral, force from a potential-energy graph, turning points, work and power.
