1. Since 1:ve varied both initial velocitv and mass= does it appear that conservation of momentum and conservation of energy\" hold across all trials regardless of initial conditions? You can look at individual trials, sets of trials svith similar conditions. as tvell as the means across all elastic trials. re there any patterns? For example; did higher mass or faster velocities do a better job of shovving momentum or kinetic energv conservation? If so: vvhv might this he? Calculate the discrepanci- a'for the mean ppmd AICE across all elastic collision trials. Remember (1' = lxexpnd xmsagwgd l. It is expected that grip and area should he Zero for elastic collisions.
