Answer»

Impulse(symbolized byJorImp) is theintegralof aforce, F, over thetimeinterval, t, for which it acts. Since force is avectorquantity, impulse is also a vector in the same direction. Impulse applied to an object produces an equivalent vectorchangein its linearmomentum, also in the same direction.TheSIunit of impulse is thenewton second(N⋅s), and thedimensionally equivalentunit of momentum is the kilogram meter per second (kg⋅m/s). The correspondingEnglish engineering unitsare thepound-second (lbf⋅s) and theslug-foot per second (slug⋅ft/s
