Impact Impact Conservation of Linear Momentum Conservation of Angular Momentum H pre = H post (m ·v) pre = (m · v) post ρ pre = ρ post (I · ω 2 ) pre = (I · ω 2 ) post

Collisions Collisions System consists of all objects involved in collisions pre-impact and post-impact Even if they are not moving ρ pre = ρ post (m ·v) pre = (m · v) post (m 1 · v 1 ) pre + (m 2 · v 2 ) pre = (m 1 · v 1 ) post + (m 2 · v 2 ) post So, for a 2 ball system…

Impacting Balls Impacting Balls Conservation of Momentum Linear and angular momentum would be conserved if surfaces were frictionless The conditions at impact influence how the momentum is distributed

Impact Impact Typically, and in reality, however energy is lost in the collision Thus, momentum tends to not be conserved Ways energy is lost: Light Sound Heat (Deformation)
