SUMMARY
The discussion centers on the conservation of spin, energy, and momentum in an isolated system, specifically using the example of a merry-go-round (MGR). It is established that angular momentum is conserved when no external net torque acts on the system, while linear momentum is not conserved due to external forces acting on the MGR. The participants clarify that energy is not conserved in inelastic collisions, as mechanical energy is transformed into heat and deformation. The conversation concludes with an understanding that linear and angular momentum are conserved independently, and they cannot be converted into one another.
