Joint Physics Sandbox

An interactive 3D physics demonstration of mechanical joints. Visitors apply force, change parameters, and watch realistic responses — hands-on physics in the browser without lab equipment or simulation software licenses.

Why physics-as-sandbox works in education:

• Students develop intuition through experimentation, not just formulas
• Same demo runs on every device a school owns — Chromebooks included
• Faculty can build curricula around it without IT installation projects

Who benefits: STEM curriculum publishers, university physics and engineering departments, after-school STEM programs, professional engineering training, museum science exhibits.

Physics formulas describe the world. Physics simulators let students play with it. The second is what creates engineers.
