Abstract
Let us consider an oscillatory system, comprising the gravitational pendulum on an elastic suspension (spring). Thus, the vertical motion of the mass happens when the spring is compressed or elongated. Since a parameter (length) of the gravitational pendulum sways periodically varies, we can sometimes observe the parametric oscillations of this angular coordinate.
