Categorizing a Physics Demonstration

AI Thread Summary
The discussion focuses on a physics demonstration involving a series of disks and springs stacked on a fixed rod, where the system is lifted and released to observe the behavior of the top disk. The primary inquiry is about categorizing this phenomenon within physics, particularly in relation to conservation of momentum and potential energy. The user initially considers the system as a coupled spring-mass system but questions its applicability due to the arrangement of the components. There is confusion regarding the mechanics of how the top disk shoots upwards upon release, prompting further clarification on the physics involved. The goal is to maximize the speed of the top disk's ascent, indicating an interest in the underlying principles of energy transfer and momentum conservation.

ABSTRACT:
I have a collection of springs and disks (masses) to choose from. I have a solid rod fixed to the ground. I slide a piece of sheet metal into the rod to act as a base. I now slide a disk into the rod. Then a spring. Then another disk. Then another spring. And one final disk. I now lift the system (from the sheet metal base) to a desired height. After releasing the system, it drops and we can observe conservation of momentum since the top-most disk will shoot upwards.

GOAL:
Under what category of physics would you place this? I want to know what I have to research in order to analyze the physics behind this reaction. (My end goal is to maximize the speed at which that top most disk flies off.)

ATTEMPTS:
I've looked into coupled, spring-mass systems, but I don't think that this will help me since my system is not so much coupled but sitting on each other.

Perhaps I misunderstand the description but how does dropping the system cause the top disc "shoot upwards"?
