Conservation of Linear Momentum JeanMine Date: vim 1. Objectives: Streia 1) Calculate the KE and momentum before and after collision. 2) Make a conclusion about the kinetic energy (KE) and momentum of a system in elastic and inelastic collisions. Il. Procedure: 1) Go to https://phet.colorado.edu/sims/html/collision-lab/latest/collision-lab_en.html 2) Select Intro 3) To make the collision elastic, drag the slider all the way to the right until it says 100% elastic. ( 0.5 x mix v . ? ) 4) Click the box, more data to get information on position, velocity, and momentum. 5) Complete Table A to D.

Conclusion 1) Describe elastic collisions in terms of KE and momentum before and after collisions. 2) Describe inelastic collisions in terms of KE and momentum before and after collisions
