Governing Physical Laws & Axiomatic Formulations

Under ISO 80000 principles, every unit conversion in this faculty is derived through exact mathematical pathways governing the underlying physical law.

Newton's Second Law of Motion

F=dpdt=m⋅a\mathbf{F} = \frac{d\mathbf{p}}{dt} = m \cdot \mathbf{a}

Defines force as the time rate of change of momentum, establishing the coherent SI derived unit Newton (N = kg·m/s²).

Hydrostatic Cauchy Stress & Pressure Tensor

P=lim⁡ΔA→0ΔF⊥ΔA=−13tr⁡(σ)P = \lim_{\Delta A \to 0} \frac{\Delta F_{\perp}}{\Delta A} = -\frac{1}{3}\operatorname{tr}(\boldsymbol{\sigma})

Defines mechanical pressure and isotropic stress, yielding the coherent derived unit Pascal (Pa = N/m² = kg/(m·s²)).

Rotational Inertia & Angular Momentum

L=I⋅ω,I=∫Vr⊥2ρ(r) dV\mathbf{L} = \mathbf{I} \cdot \boldsymbol{\omega}, \quad I = \int_V r_{\perp}^2 \rho(\mathbf{r}) \, dV

Relates angular velocity to angular momentum via the moment of inertia tensor [M L²] (kg·m²).
