Impulse and Momentum 1. Derive the Impulse formula using calculus. p = p f – p i = F dt 2. Use the Derivation to solve problems that relate to momentum, force and impulse 3. Create an Impulse- momentum AP Physics Problem.

Lesson 2 : Impulse and Momentum F = d(mv) dt dp = dt dp = F dt Integrating F with respect to t, p = p f – p i = F dt tftf titi Impulse (J) F dt tftf titi J =
3
Impulse – Momentum Theorem p = p f – p i = F dt tftf titi The impulse of the force F acting on a particle equals the change in the momentum of the particle. J = p

a. f(t) =6t 5 b.p’(t) =t 999 c. POWER RULE PRACRICE
6
a.If f(t) =6t 5, then J= t 6 b.If p’(t) =t 999, then P(t)= t 1000 /1000 c.If, then y = t 4 Solutions POWER RULE
7
Example Let p’(t) = 2t 3 + t = F(t) Then the Integral is ½ (t 4 + t 2 ) Yep it’s that simple……
8
Now you make up a function F(t) = Take the Integral J = Impulse
