gP gPhysics Interactive physics simulations
Physics in Motion

Explore physics through responsive, visual, interactive simulations.

gPhysics brings together simulations, tutorials, labs, and visual experiments across mechanics, waves, optics, electricity, fluids, and more. Start with a category, dive into a concept, and learn by interacting with it.

A clearer overview of the project, the author, and the tools behind the simulations.

Built for education

The project

gPhysics is a growing collection of interactive physics simulations designed to make abstract ideas more visual, intuitive, and teachable. The goal is simple: help learners interact with the concept, not just read about it.

The author

All of the content on this site was created by Geethu. The site reflects years of classroom-centered physics teaching and a steady commitment to building useful learning tools over time.

Built with GeoGebra

Most of the animated illustrations and interactive simulations were created using GeoGebra. For more information about the software, visit www.geogebra.org.
