What are the quantities that characterize mechanical vibrations. Give a definition for each characteristic of the vibrations.

Displacement х (m) – body deviation from the equilibrium position; The vibration amplitude x (m) is the maximum distance the body deviates from the equilibrium position;
The period of oscillations T (s) is the time of one complete oscillation; Vibration frequency v (Hz) is the number of vibrations per unit of time.

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.
