Considering each atom in a solid as one of these yields the Einstein model of heat capacity.
Considering each atom in a solid as one of these yields the Einstein model of heat capacity. Via Taylor expansion around a local minimum, this model may be applied to any system with a non-vanishing second derivative of potential. Systems of this type can be classified by their Q value as (*) underdamped, critically damped, or overdamped, and their frequency is given as the square root of quantity stiffness over mass. Found in all systems with a linear restoring force, for 10 points, name this simple system exemplified by a mass on a spring.
