PhET Collision Lab: Introduction in One DimensionLearning goals:Draw "before-and-after" pictures of collisions.Construct appropriate vector representations of "before-and-after" collisions.Explain what variables are conserved and under what conditions.What does “elasticity” mean?Identify vector and scalar quantities.Directions:1.Experiment with one-dimension elastic collisions(Check 1dand set elasticity at 100%).Make a tablelike this to help you organize your thoughts about collisions; use landscape layout so you can fiteverything; “x” means there would not be a drawing in that box. Try varying mass and initial speed(including some initial zero velocity). I am expecting several trials. TheRestartbutton is handy forreplaying an experiment.Mass1Mass2Initialvelocity1Initialvelocity2InitialtotalvelocityInitial totalmomentumKineticenergyinitialFinalvelocity1Finalvelocity 2
