Free Density and Buoyancy Simulator
Density and Buoyancy Simulator turns Archimedes principle into a hands-on browser lab: pick a material, set mass and volume, choose water, salt water, oil, alcohol, or custom liquid density, then drag the object into the tank and watch every calculation update.
Built for density comparison, buoyant force calculation, displaced fluid volume, and classroom physics practice.
Start Density and Buoyancy Simulator here: choose the object material, mass, volume, and liquid, then drag the object into the tank to compare object density, liquid density, displaced volume, buoyant force, and weight.
Select a material preset, adjust mass and volume, choose a liquid, then drop the object into the tank.

Density and Buoyancy Simulator conclusion
Change one variable at a time. Increasing volume lowers object density when mass stays fixed, and increasing liquid density makes floating easier.
Density and Buoyancy Simulator uses an ideal fluid model with g = 9.81 m/s². Surface tension, fluid flow, and object shape details are simplified so the density comparison stays clear.
Density and Buoyancy Simulator connects object density, liquid density, displaced volume, buoyant force, and weight in one visible workflow.
Choose wood, plastic, aluminum, steel, or custom material, then adjust mass, volume, and liquid type while Density and Buoyancy Simulator recalculates density instantly.
Drop the object into the tank and use Density and Buoyancy Simulator to compare buoyant force, weight, displaced liquid volume, and float-sink state.
Use this Density and Buoyancy Simulator guide to connect density formula, Archimedes principle, floating, suspension, and sinking.
Choose a material preset or custom object, set mass and volume, then choose water, salt water, oil, alcohol, or custom liquid density.
Change one input at a time. Keep mass fixed and increase volume to lower object density, or keep the object fixed and increase liquid density to make floating easier.
Use the object density, liquid density, displaced volume, buoyant force, weight, and net force cards to write a clear Archimedes principle conclusion.
For homework, state the density comparison first, then support it with buoyant force versus weight.

Fast answers about Density and Buoyancy Simulator density, liquid density, displaced volume, buoyant force, weight, floating, suspension, and sinking.
Yes. Density and Buoyancy Simulator runs in the browser and can be used without an account or installation.
Density and Buoyancy Simulator calculates object density as mass divided by volume. The page shows the result in kg/m³ so it can be compared directly with liquid density.
Density and Buoyancy Simulator uses Archimedes principle: buoyant force equals liquid density times gravity times displaced liquid volume.
An object floats when its average density is lower than the liquid density. In that case Density and Buoyancy Simulator shows only part of the object submerged, with buoyant force balancing weight.
Yes. When object density and liquid density are nearly equal, Density and Buoyancy Simulator marks the object as suspended and places it in the liquid instead of at the surface or bottom.
Open Density and Buoyancy Simulator, choose a material, set mass and volume, then drag the object into water, salt water, oil, alcohol, or a custom liquid.
Use the live density, displaced volume, buoyant force, weight, and net force cards to explain why the object floats, stays suspended, or sinks.
