PHET Collision Lab We will be looking at a series of collisions using the simulation software at the web address (https://phet.colorado.edu/sims/html/collision-lab/latest/collision-lab_all.html). Go to the web address and click on the "Explore 1D" image to start the Ball Mass simulation. kg 0.5 Once loaded, click on the "More Data" button on the 1.5 bottom of the simulation. This will allow you to control positions, initial velocities, and masses. More Data Scenario #1: Elastic collisions between balls of equal mass with random initial velocities 1. We will look at three different completely elastic collisions. In each collision what do you expect to see in terms of momentum? Velocity Vectors Momentum Vectors Center of Mass | Momenta Diagram Kinetic Energy Show Values Elasticity 100% Inelastic Elastic 2. Fill in the table choosing different velocities for each object. Clicking on the "Show Values" option will allow you to get the velocities after the collision. Make sure to also de-select “Reflecting Border".
