Definition

quotient of internal energy and mass:

u = \frac{U}{m}

where $U$ is internal energy (internal energy) and $m$ is mass (ISO 80000-4: Mechanics)

quotient de l'énergie interne par la masse:

u = \frac{U}{m}

où $U$ est l'énergie interne (internal energy) et $m$ est la masse (ISO 80000-4: Mechanics)
