Conservation of Momentum & Energy Laboratory as be Go to: https://phet.colorado.edu/en/simulation/legacy/collision-lab pingfie rse He Go to the "Introduction" tab. Set the initial velocity by clicking the velocity vector and dragging it to the right (positive velocity) or left (negative velocity). . Total momentum (p) is calculated by finding the sum of P1 and P2. Part 1: Totally Elastic Collisions .
