Is embedding the inclined plane simulator free?

Yes. It is free to embed on any site, with no account, no API key and no usage limits. The whole simulation runs in your visitor’s own browser, so there is no server cost — we only ask that you keep the small "Inclined Plane Simulator by LK Forge" credit line that comes with the embed code.

What can visitors do with the embedded simulator?

They can set the ramp angle, the coefficient of friction and the mass of the block, then watch it either stay held by friction or break loose and slide down. A live panel shows the component of gravity along the slope, the normal force, the friction force, the acceleration and whether the block is static or sliding, with the three force arrows drawn on the block.

Does the embed teach how to resolve forces on a ramp?

Yes. Gravity is split into mg·sinθ along the slope and mg·cosθ into it, the normal force N = mg·cosθ is shown, and friction is drawn opposing motion up to μN. Students see the block hold while tanθ is at or below μ and slide once the angle passes that, accelerating at a = g(sinθ − μcosθ) — with the mass cancelling out.

What iframe height should I use, especially on mobile?

The snippet ships with height="800", which is tall enough that the ramp, the sliders and the readouts all fit without clipping even on a narrow phone where everything stacks into a single column. On a wider page the widget simply centres within its max-width of 560px. If you want it shorter you can lower the height, but 800 is the safe default across screen sizes.

Where can I embed it — WordPress, Wix, Squarespace, Notion?

Anywhere you can add HTML, because it is a standard iframe. In WordPress use a Custom HTML block; in Squarespace a Code/Embed block; in Wix an Embed HTML element; in Ghost an HTML card; in Notion paste the /embed/inclined-plane/ URL as an embed. On a plain HTML page or an intranet, paste the snippet straight into the markup.

Does the embedded simulator track visitors or set cookies?

No. Everything runs locally in the visitor’s browser — nothing is uploaded. The embed sets no tracking cookies and sends no analytics, so it is safe to place on a privacy-sensitive site, an intranet, or a page for students.

How to Add an Inclined Plane Simulator to Your Website

LK Forge · 4 min read · Updated September 2026

You can add a full inclined plane simulator to any website, blog, or classroom page with a single line of code — free, with no sign-up, no plugin, and no script to install. Visitors put a block on a ramp and watch friction hold it or the slope win. This guide covers the fastest way to embed the Inclined Plane Simulator, what it teaches, and where it works.

The quickest way: paste one embed snippet

An embed is just an <iframe> that loads the simulator from lkforge.com, plus a small credit line. Copy this into your page’s HTML where you want the widget to appear:

<iframe src="https://lkforge.com/embed/inclined-plane/"
        width="100%" height="800" loading="lazy"
        style="border:0;max-width:560px"
        title="Inclined Plane Simulator by LK Forge"></iframe>
<p><a href="https://lkforge.com/tools/physics/inclined-plane/">Inclined Plane Simulator</a>
   by <a href="https://lkforge.com/">LK Forge</a></p>

The <iframe> is the live simulator; the <p> underneath is a plain credit link. Keep that line — the visible link is what keeps the widget free to embed. You can also copy this exact code straight from the LK Forge widget gallery.

What the widget shows

The simulator opens with a block on a ramp, so a visitor sees the forces immediately and can then take control:

Ramp angle: tilt the slope and watch the down-slope pull grow.
Friction: raise or lower the coefficient and find the angle where the block breaks loose.
Mass: change it and confirm the acceleration does not — the mass cancels.
Live readouts and arrows: the along-slope force, the normal force, the friction, the acceleration and whether it holds or slides.

Pick the right height

The snippet uses height="800", which fits the ramp, the sliders and the readouts without clipping even on a narrow phone, where they stack into one column. On a wider page the widget centres within its max-width:560px. That single height works across screen sizes, so there is nothing to tweak for mobile.

Where it works

Because it is a standard iframe, the embed works anywhere you can add HTML:

WordPress: add a Custom HTML block and paste the snippet.
Squarespace: use a Code / Embed block.
Wix: add an Embed HTML / iframe element.
Ghost: insert an HTML card.
Notion: paste the /embed/inclined-plane/ URL and choose "Create embed".
Plain HTML, an intranet, or a lesson page: paste the snippet straight into the markup.

That’s the whole job. Copy the embed code from the widget gallery and paste it wherever a physics lesson or a blog post on forces, friction or Newton's laws needs a ramp students can actually tilt.
