# Conservation of Momentum

Conservation of momentum means that the momentum of a rigid body interacting with another rigid body will be the same on both sides of the equation. Refer to equation 1 for the conservation of linear moment, and equation 2 for the conservation of angular momentum.

(Eq 1)  $mv_1=mv_2$

m = mass

v1 = Initial velocity

v2 = Final velocity

(Eq 2)  $Iϖ_1=Iϖ_2$

I = Moment of Inertia

ϖ1 = Initial anglular velocity

ϖ2 = Final anglular velocity
