PHYS 140 Linear Momentum Lab 9 Name: _____________________________________ Objective The objective of this lab is to verify conservation of linear momentum in elastic and inelastic collisions, and study the kinetic energy under each of these two cases. Background Momentum: 𝑝 = 𝑚𝑣 Kinetic Energy: 𝐾 = 1 2 𝑚𝑣 2 Conservation of Liner Momentum (for Elastic and Inelastic Collisions): 𝑚 1 𝑣 1,𝑖 + 𝑚 2 𝑣 2,𝑖 = 𝑚 1 𝑣 1,𝑓 + 𝑚 2 𝑣 2,𝑓 Conservation of Kinetic Energy (for Elastic Collisions): 1 2 𝑚 1 𝑣 1,𝑖 2 + 1 2 𝑚 2 𝑣 2,𝑖 2 = 1 2 𝑚 1 𝑣 1,𝑓 2 + 1 2 𝑚 2 𝑣 2,𝑓 2 Procedure Go to: https://phet.colorado.edu/sims/html/collision-lab/latest/collision-lab_en.html Select Explore 2D . Select More Data . Run the simulation for the 100% Elastic Collision and 0% Elastic (Inelastic) Collision. Collect the data and complete the tables in the Data section.
