potential energy
energy due to the position in a force field, equal to the opposite of the line integral along a curve C of a conservative force F, thus V= C Fdr MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaadAfacqGH9aqpcq GHsisldaWdraqaaiaahAeacqGHflY1jugqbiaacsgakiaahkhaaSqa aKqzaeGaae4qaaWcbeqdcqGHRiI8aaaa@449A@ , where dr is vector line element

NOTE 1 A force is conservative when the force field F(r) is static and irrotational, i.e. rot F = 0, in a simply connected domain.

NOTE 2 Force F is the gradient of potential energy V, thus F = grad V. See also “potential” (113-03-19).

NOTE 1 Une force est conservative quand le champ F(r) est statique et irrotationnel, c'est-à-dire que rot F = 0, dans un domaine simplement connexe.

NOTE 2 La force F est le gradient de l’énergie potentielle V, soit F = grad V. Voir aussi «potentiel» (113-03-19).
