Definition

vector (ISO 80000-2: Mathematics) quantity describing the effect of moment of force during a time interval:

$H (t_{1}; t_{2}) = \int_{t_{1}}^{t_{2}} M d t$

where $M$ is moment of force (moment of force), $t$ is time (ISO 80000-3: Space and time) and $[t_{1}, t_{2} \$ ] is considered time interval

grandeur vectorielle définie l'effet d'un moment de force pendant un intervalle de temps :

$H (t_{1}; t_{2}) = \int_{t_{1}}^{t_{2}} M d t$

où $M$ est le moment force (moment of force), $t$ est le temps (ISO 80000-3: Space and time) et $[t_{1}, t_{2} \$ ] est l'intervalle de temps considéré

Notes

For a time interval $[t_{1}, t_{2} \$ ],

$H (t_{1}, t_{2}) = L (t_{2}) - L (t_{1}) = Δ L$

where $L$ is angular momentum.

Pour un intervalle de temps [t1, t2],

$H (t_{1}, t_{2}) = L (t_{2}) - L (t_{1}) = Δ L$

où $L$ est le moment cinétique.
