Fluids and Pressure

Go with the Flow: Understanding Liquids and Gases

Fluids (liquids and gases) behave differently from solids. This unit covers how fluids move, how they push on objects, and why things float.

Key Principles

  • Buoyancy: Why some things float and others sink.
  • Pascal's Principle: Pressure applied to a fluid is transmitted undiminished.
  • Bernoulli's Equation: Fast-moving fluids have lower pressure.

MCAT Essentials

You'll work with equations like \( P = \frac{F}{A} \) and \( \rho = \frac{m}{V} \), and understand real-world systems like blood flow and air travel.

Everyday Connections

  • Blood pressure cuffs use fluid pressure.
  • Airplanes use Bernoulli's principle to create lift.

Key Formula

\[P = \frac{F}{A}\]

Examples

  • Measuring a patient's blood pressure.

  • Explaining how a straw draws up liquid.

In a Nutshell

Fluids and pressure explain phenomena from blood flow to airplane flight.

Key Terms

Buoyancy
The upward force on an object in a fluid.
