natural vibration

physics
Also known as: free vibration

Quick Summary

In physics, natural vibration refers to the periodic back-and-forth motion of a system when it's displaced from its equilibrium position and allowed to respond to restoring forces. This type of motion is often described as simple harmonic motion (SHM), characterized by repetitive movement through an equilibrium point with equal maximum displacements on either side.12

Key aspects of natural vibration include:
* Restoring Force: A force that always directs towards the equilibrium position and is proportional to the displacement from it, often following Hooke's law (F = -kx).2
* Constant Period: The time for each complete vibration remains the same, regardless of the amplitude.2
* Damping: The gradual decrease in vibration amplitude due to energy dissipation, such as friction.31

Many physical systems exhibit natural vibrations, including pendulums and masses attached to springs, forming the basis for timekeeping devices and understanding wave phenomena.21
