Density is the mass of a substance per unit volume (ρ = m/V). It determines whether objects float or sink, is used in material identification, and underpins buoyancy and fluid dynamics.

ステップバイステップガイド

1. 1Density (ρ) = mass / volume
2. 2Mass = density × volume
3. 3Volume = mass / density
4. 4Objects float in a fluid if their density is less than the fluid's density
