Tidal force

Differential gravitational <acceleration>, multiplied by the affected <mass>, across a spatially extended body. In the linear approximation the <acceleration> difference is $T\Delta\boldsymbol r$, where $T$ is the <tidal tensor>. Stellar <tidal forces> limit the domain of a <circumplanetary orbit>; sufficiently strong ones can produce <tidal disruption>.
