# Dynamics: 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.

(1)

m = mass

v_{1} = Initial velocity

v_{2} = Final velocity

(2)

I = Moment of Inertia

ω_{1} = Initial anglular velocity

ω_{2} = Final anglular velocity
