Definition

quotient of Helmholtz energy and mass:

a = \frac{A}{m}

where $A$ is Helmholtz energy (Helmholtz energy) and $m$ is mass (ISO 80000-4: Mechanics)

quotient de l'énergie libre par la masse:

a = \frac{A}{m}

où $A$ est l'énergie libre (Helmholtz energy) et $m$ est la masse (ISO 80000-4: Mechanics)
