About this Simulation

This simulation models the buoyancy force exerted on submerged or partially submerged objects in fluids. Learners can adjust object mass, size, and fluid density to observe how these variables affect whether objects float, sink, or hover. Real-time visualisations show the relationship between weight, buoyant force, and net motion.

Learning objectives: Understand how buoyancy force depends on fluid density and object volume | Predict and explain floating and sinking behaviour using Archimedes' principle | Explore the balance between gravitational and buoyant forces on objects
