CK-12 Simulations

The platform offers browser-based simulations covering topics across the physics curriculum, with each simulation presenting a real-world context that allows users to manipulate variables and observe the resulting physical behaviour. The simulations are accessible through a web interface at interactives.ck12.org, and companion applications are available through the Apple App Store and Google Play for use on mobile and tablet devices.

The simulations are produced by the CK-12 Foundation, a non-profit organisation that provides open educational resources. The content is aimed at secondary and early tertiary education, supporting classroom instruction, homework activities, and independent study.

Each simulation typically includes interactive controls, on-screen readings, and accompanying questions or explanations that link the simulated scenario to underlying physics principles such as mechanics, electricity, magnetism, waves, and thermodynamics. The resources are made freely available to teachers and students, and integrate with the wider CK-12 ecosystem of FlexBooks, practice exercises, and adaptive learning tools.
