Fluids

Welcome to Fluids! This section covers the mechanics of liquids and gases, focusing on how pressure, density, and flow govern everything from the buoyancy of a ship to the lift on an airplane wing.

🚧 Fluids content is currently in development. Full lessons, skills, and problems will roll out during the 2026–2027 school year.

Fluids are materials that can flow and change shape, like the water in this splash. When an object moves through a fluid, or when a fluid moves around an object, it creates a force called pressure.
