Density

Definition

Mass per unit volume: $\rho = \frac{m}{V}$ . Materials with higher density have more mass for the same volume.

Used by AQA

Paper 1

Density is mass per unit volume. Imagine two solid blocks with exactly the same dimensions but made from different materials.
Revise: Material properties
Mass per unit volume: a low-density material has less mass than a high-density material of the same volume.
Revise: Commercial application of properties

1
Low density does not automatically mean low strength. Density describes mass per unit volume, not resistance to force.
