The simplest type of vibrating system is called a single-degree-of-freedom spring-mass system. The spring is characterized by its spring rate, K, and a mass, M. This system is called a single-degree-of-freedom system because motion can occur in only one direction. Spring rate defines the force required to induce a unit deflection of a spring.
