About this Simulation

This interactive Cartesian diver simulator models how pressure changes in a closed system affect the buoyancy and motion of a submerged diver. Learners can adjust variables like container dimensions, diver size, and applied pressure to observe how gas compression and expansion influence whether the diver sinks or floats, connecting abstract pressure concepts to real-world behaviour.

Learning objectives: Understand the relationship between pressure and gas volume in a closed system | Explain how pressure changes cause changes in buoyancy and diver motion | Apply Boyle's law principles to predict diver behaviour under different pressure conditions
