    • Describe a fourth scenario in which either the Law of Conservation of Matter or the Law of Conservation of Energy could be observed. Using as many sentences as needed, describe how an experiment could be set up to further explore your recorded observation. The goal is to show understanding of the concepts in the lesson.

    About the conservation of energy. Suppose you are in a vacuum and you bunch a basketball. You will notice that no matter how much you will leave the ball bunching the ball will never stop. That happens because the ball develops both potential and kinetic energy, the sum of those two give us the mechanical energy which remains constant. We have to suppose that friction is zero otherwise you have to count for thermal loses etc. But in ideal conditions the example i gave you is just fine.
