Pressure & Pascal's Law
A fluid is anything that can flow — both liquids and gases. Unlike a solid, a fluid cannot sustain a shearing stress at rest, so it takes the shape of…
Start this topic → 2Buoyancy, Viscosity & Bernoulli's Principle
When a body is immersed in a fluid, the pressure on its lower surface is greater than on its upper surface (because pressure increases with depth). Th…
