NOTE 1 For a time interval [t1, t2], impulse is equal to the change of momentum p, thus I = p(t2) − p(t1) = Δ p.

NOTE 2 In French, the term "impulsion" has also another meaning corresponding to English "pulse".

NOTE 3 The coherent SI unit of impulse is newton second, N⋅s.

impulsion, f
grandeur vectorielle égale à l'intégrale de la force F par rapport au temps t, soit I= t 1 t 2 F dt MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaahMeacqGH9aqpda WdXaqaaiaahAeaaSqaaiaadshadaWgaaadbaGaaGymaaqabaaaleaa caWG0bWaaSbaaWqaaiaaikdaaeqaaaqdcqGHRiI8aKqzafGaaeizaO GaamiDaaaa@4404@ étendue à l’intervalle de temps [t1, t2]

NOTE 1 Pour un intervalle de temps [t1, t2], l'impulsion est égale à la variation de la quantité de mouvement p, soit I = p(t2) − p(t1) = Δ p.

NOTE 2 En français, le terme «impulsion» a aussi un autre sens correspondant à l'anglais «pulse».

NOTE 3 L'unité SI cohérente d’impulsion est le newton seconde, N⋅s.
