Run the physics. Export the clip. Beat the challenge.
Hands-on physics simulations built for teachers, students and hobbyists who want more than a diagram: real physics computed on our servers, gamified challenges, and video export up to 4K you can actually share.
Not the biggest catalog. The one built to be shared.
Plenty of free simulation libraries have hundreds of tools. We have 43, chosen and polished on purpose. What you get here that they don't:
Video export up to 4K
Run a simulation, then export the clip itself, not a screenshot: 480p on Launch, 1080p on Orbit, 4K on Interstellar, ready to post.
Gamified challenges
Challenge modes with server-authoritative scoring — your result is verified, not just a number your browser made up.
Real physics, real polish
The equations are integrated on our servers, not approximated in your browser, with the visual polish a classroom demo or a shared clip deserves.
Built for
Teachers
A clean, reliable demo to run in front of a class or drop into a lesson.
Students
Build intuition by adjusting the sliders and watching the physics respond.
Enthusiasts
Chase a better challenge score, export the run, and share it.
