Linear Momentum Formula: P=mv =kg*m/s -Momentum equals mass times the velocity -if a heavier object has twice the mass of a lighter object but the lighter object has twice the velocity, the momentum of the two objects are equal -to calculate the change in momentum of an object after a collision: Δ P= P(final)-P(initial) to calculate the total magnitude of total momentum: P(total)= [(p(total in x-direction)^2)+(P(total in y-direction)^2)] Momentum in relation to Newton’s 2 nd Law ΣF=ma Total Force= mass time acceleration …but in the case of momentum we alter the formula to relate to momentum : F=( Δ p/ Δ t) -total force equals the change in momentum divided by the change in time Note: Δ

Unformatted text preview: p=mv(final)-mv(initial) Δ Impulse I=F av Δ 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 Δ p Fav=(Δ p Δ /Δ t) -when linear momentum is conserved: Fnet= Δ F(ext) because the F(internal) always cancels out ….so. . Δ pnet= Δ F(ext) Δ t -you can also find acceleration using the alteration of this formula: a=( Δ 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 *******...
