Two dimensional curved disks on a sphere: the evolution of kinetic energy
curved space kinetic energy
2009/12/30
We put disks on a sphere between two parallels of this sphere. The disks have the curvature of the sphere and interact via a simplified Hertz law. We analyze the behavior of the total kinetic energy o...
