Name Go to Phet and find collision lab or type in http://phct.colorado.el'icellion acollision labcn.ba Set up your page so it looks like this Momenta MA BEEEEE Have 1 Dimension selected, velocity vectors, center of mass, and momentum diagram Elasticity is set at 1.00 On the bottom, select "More Data", this will give mass, as well as velocity and momentum values. Collision 1: Same Mass Predict, with the current set up, AFTER collision -what will each object's velocity and momentum be prior to and after collision (use formulas if needed!) Pr Ve Va Pa P m₂ PH Pe m₂ Pa V₂ Vii 1 predictions 1 -2 1 -2 real results ON WE 150 Key: m-mass, v velocity, p-momentum,,-object 1, object 2, initial (prior to collision), final (post collision) then record the data. Let's see how you did, Hit the PLAY button, Add your two initial momentums and your two final momentums Pines P What do you notice about the momentum before and after? pmv Pune - PitP; Collision PHET Lab
