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 momentum-impulse 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 *******...
