Free Density and Buoyancy Simulator

Density and Buoyancy Simulator change material, mass, volume, and liquid density to see why objects float or sink

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.

Density and Buoyancy Simulator conclusion

Density and Buoyancy Simulator experiments

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 FAQ

Fast answers about Density and Buoyancy Simulator density, liquid density, displaced volume, buoyant force, weight, floating, suspension, and sinking.

Is Density and Buoyancy Simulator free?

Yes. Density and Buoyancy Simulator runs in the browser and can be used without an account or installation.

What formula does Density and Buoyancy Simulator use for density?

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.

How does Density and Buoyancy Simulator calculate buoyant force?

Density and Buoyancy Simulator uses Archimedes principle: buoyant force equals liquid density times gravity times displaced liquid volume.

Why does an object float in Density and Buoyancy Simulator?

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.

Can Density and Buoyancy Simulator show neutral buoyancy?

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.

Start Density and Buoyancy Simulator now

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.
