Density and Pressure (Leaving Cert Physics): Flashcards

Mass per unit volume

$\rho = \frac{m}{V}$

kg m⁻³ (kilograms per cubic metre)

Scalar quantity

Displacement method

Object density < fluid density

Object density > fluid density

Force per unit area

$P = \frac{F}{A}$

Pascal (Pa)

$1 \text{ N m}^{-2}$

Reduces pressure
