What is an oscillating system? Give examples of oscillatory systems.

Systems of bodies in which free oscillations are possible are called oscillatory systems. Each oscillatory system has a state of stable equilibrium, relative to which oscillations occur. If you take the oscillatory system out of a state of stable equilibrium, then a force always appears, directed in the opposite direction to the deviation (displacement). Under the influence of this force, the system seeks to return to its initial stable state. For example, a body suspended from a spring or a thread, the branches of a tuning fork vibrate if these bodies or branches of a tuning fork are removed from the state of the equilibrium device – to stretch the spring, deflect the ball on the thread from a vertical position, hit the tuning fork branches with a hammer.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
