Coupled systems displaying this sort of behavior can exhibit normal modes, examples of which include symmetric and asymmetric stretching.
Coupled systems displaying this sort of behavior can exhibit normal modes, examples of which include symmetric and asymmetric stretching. This behavior is modeled with a second order homogeneous differential equation with a term corresponding to damping. This behavior occurs in RLC circuits analagously to a certain mechanical system with a dashpot. This sort of motion will typically occur in systems with a restoring force, such as systems which obey Hooke's law. In its simplest case this sort of motion can be described with a sine function. For 10 points, name this sort of behavior which occurs in the simple harmonic motion seen in a spring.
