Calculate pressure differences in liquids

Forces and motion • Pressure in fluids

Key concepts

What you'll likely be quizzed about

  • Pressure in a liquid is defined as the force exerted per unit area.
  • It is calculated using the formula: Pressure (P) = Force (F) / Area (A).
  • As depth increases, the pressure also increases because the weight of the liquid above contributes to the total pressure.
  • The density of the liquid plays a crucial role in this calculation.

What factors affect pressure differences in liquids?

Click to reveal answer

Pressure differences depend on liquid density, height difference, and gravity.

Key notes

Important points to keep in mind

Pressure increases with depth in liquids

Use correct units: Pascals for pressure

Remember that density affects pressure calculations

Always consider the weight of the liquid above when calculating pressure

Be mindful of the gravitational constant when using formulas
