This comes with the lab and the solution manual. This online lab assignment is separated into 3 parts: elastic, inelastic, and 2D elastic collisions. Feel free to omit the last part if you don't want to go over 2D. The lab allows students to investigate how momentum and kinetic energy transfer in different types of collisions. Relative velocity is also analyzed to confirm that, for elastic collisions, the relative speed of approach is equal to the relative speed of separation. Students are also
