Interactive Physics · Pilot Edition
A textbook made of simulations.
Browse Physics as a coherent book. Each chapter points to simulations, videos, teacher notes, concept checks, and local progress tracking on this device.
Start learning Open Thermal PhysicsHow The Book Adapts
Students mark interactives as studied, answer concept checks on resource pages, and set confidence per chapter. The textbook reads those local signals and keeps the navigation focused on the next useful chapter.
Kinematics
Describe motion using displacement, velocity, acceleration, graphs, and multiple representations.
