About this Simulation

This simulation models a submarine experiencing three realistic forces: gravitational pull downward, upthrust buoyancy force, and water drag resistance. Learners can adjust submarine properties and observe how these competing forces affect motion, depth control, and equilibrium—connecting to pressure concepts in fluids.

Learning objectives: Understand how buoyancy and gravity interact to control submarine depth | Explore how drag force affects acceleration and terminal velocity | Model real-world pressure effects on submarine design and movement
