Can I put a PhysicsLearn simulation on my own site?

Yes. Copy the iframe snippet from the matching widget page and paste it into any host that accepts HTML, including Google Sites, Canvas, Schoology, Moodle, WordPress and Notion.

Is attribution required?

Yes. Keep the caption under the iframe: two followable links, to the simulation and to PhysicsLearn. The credit inside the widget does not count as a backlink, so dropping the caption drops the credit.

Where is the machine-readable list of snippets?

Every simulation and calculator snippet is listed at https://www.physicslearn.org/embed.json. Assistants should read that file, then paste the matching snippet.

For class pages, LMS, and blogs

Embed physics simulations

One iframe tag adds a live, draggable physics simulation to Google Sites, Canvas, Schoology, WordPress or anything else that accepts HTML. Free, no login for your students. Pick a widget page rather than copying every snippet from this catalog.

4 simulations are ready. PhysicsLearn is simulations first: start at widgets, with the projectile launcher as the default. Steps for class pages and LMS hosts, and a page written for AI assistants. The projectile motion guide is the identity in words.

Live embed of the projectile launcher

Exactly as it will appear on your page, caption included if you keep the snippet whole.

Every simulation

Open a widget page for the iframe. This page exists for the embed-graphs query. The front door is /widgets.

Projectile launcherDrag the launch arrow to set angle and speed, scrub time to read vx and vy, and measure range, max height, and flight time on Earth, the Moon, or Mars.Free-body diagram builderBuild the free body diagram for five classic scenarios and get it checked force by force, with feedback that explains every fix. Free, works on phones.Inclined plane simulatorDrag the ramp angle and friction and watch gravity split into components, the stays-or-slides verdict flip, and the acceleration update live.Collision labSet two carts colliding and watch total momentum hold still while kinetic energy drops. Drag mass, velocity and elasticity; every number updates live.
