The simplest automated aquiver arrangement is a weight absorbed to a beeline bounce accountable to alone weight and tension. Such a arrangement may be approximated on an air table or ice surface. The arrangement is in an calm accompaniment if the bounce is static. If the arrangement is displaced from the equilibrium, there is a net abating force on the mass, disposed to accompany it aback to equilibrium. However, in affective the accumulation aback to the calm position, it has acquired drive which keeps it affective above that position, establishing a new abating force in the adverse sense. If a connected force such as force is added to the system, the point of calm is shifted. The time taken for an cadence to action is generally referred to as the oscillatory period.
