A central force and a potential with this degree with respect to distance are the only ones whose bound orbits are all closed orbits, according to Bertrand's theorem.
The magic angle can be obtained by solving a Legendre polynomial with this degree found in the z component of a magnetic dipole's B field. A central force and a potential with this degree with respect to distance are the only ones whose bound orbits are all closed orbits, according to Bertrand's theorem. In a potential well dependent on this power of position, all of the energy levels are (*) equally spaced. In a system with this many bodies, an additional, much smaller body can stably fit in one of five Lagrange points. This is the highest value of n such that the n-body problem is exactly solvable, and the potential energy of a spring is proportional to this power of displacement. For 10 points, what cardinal number corresponds to a law stating the entropy of the universe always increases?
