Learn about vibration , the oscillatory motion of an object around a reference position, and its effects on engineering, science, and health. Explore the types, sources, and testing of vibration , and how to measure and control it. In Physics, vibration is defined as a mechanical oscillation or a rapid, periodic back-and-forth motion of an object about its position of equilibrium. It is a fundamental concept in mechanics and wave theory. Common examples include the movement of a guitar string after being plucked or the motion of a pendulum. Mechanical Vibrations – Definition, Types, Applications What is Vibration ? Vibration is a periodic motion of an object about an equilibrium position. It can be a simple harmonic motion or a more complex motion. Vibration is the movement of energy through matter or space. In physics, vibration is defined as a back-and-forth motion of an object or wave. Vibration can be caused by external or internal forces and can occur in solids, liquids, gases, or plasmas. It can be caused by a force ... Learn about the properties, causes, and effects of vibrational motion, such as the back and forth of a bobblehead doll. Explore the concepts of restoring force, period, frequency, amplitude, and damping with examples and diagrams.
