Unformatted text preview: p=mv(final)mv(initial) Impulse I=F av t= mg*m/s  Impulse equals average force times the change in time  This formula can be altered to relate to momentum, which we call the momentumimpulse theorem: I=Fav p Fav=( p / t) when linear momentum is conserved: Fnet= F(ext) because the F(internal) always cancels out .so. . pnet= F(ext) t you can also find acceleration using the alteration of this formula: a=( F/m) this formula is commonly used when working with springs lastly, you can alter the same formula to find the velocity of an object: v=(p/m) ******remember to label the X and Y apply is accordingly to the problems; STAY CONSISTENT *******...
