Kyle has conducted a virtual experiment using a PhET simulationto carry out a series of collisions. In the simulation, he set themass and initial velocity of each object, then tried the collisionand recorded the final velocity. Students calculate the initial andfinal momentum of each object, as well as the initial and finalmomentum of the system. He recorded the results in a table.
Which conclusion can be derived from this result?
The momentum of mass 1 is conserved
The momentum of mass 2 is conserved
Total momentum of mass 1 and mass 2 is conserved
Total momentum of mass 1 and mass 2 is not conserved
