What is the difference between oscillations and vibrations?

As a domain expert in the field of physics, I can provide a comprehensive explanation of the differences between oscillations and vibrations. These two terms are often used interchangeably in everyday language, but they have distinct meanings in the context of physics and engineering. Step 1: English Explanation Vibration refers to the mechanical phenomenon where an object moves back and forth around an equilibrium position, typically with a consistent frequency. The motion is periodic, which means it repeats its cycle over a fixed period of time. The restoring force in a vibration is usually due to the elastic properties of the object. This force acts to bring the object back to its equilibrium position whenever it is displaced. An example of vibration is the movement of a plucked guitar string, which oscillates back and forth due to the tension in the string. Key characteristics of vibration: 1. Periodic Motion: The object moves in a pattern that repeats at regular intervals. 2. Restoring Force: The force that acts to return the object to its equilibrium position is due to the object's elasticity. 3. Energy Source: The source of energy that maintains the vibration can be internal (like a spring) or external (like a driving force). On the other hand, oscillation is a more general term that can encompass a wider variety of periodic motions, not just those caused by elastic forces. An oscillation can be caused by a restoring force that is not necessarily elastic in nature. A classic example of oscillation is the motion of a pendulum, where the restoring force is gravity pulling the pendulum back towards its lowest point. Key characteristics of oscillation: 1. Periodic Motion: Similar to vibration, oscillation involves a repeating cycle of motion. 2. Restoring Force: The force that brings the system back to its equilibrium position can be due to gravity, electromagnetic forces, or other forms of potential energy. 3. Damped or Undamped: Oscillations can be damped, where the amplitude of the motion decreases over time due to resistance, or undamped, where the motion continues indefinitely without loss of energy. It's important to note that while all vibrations are a form of oscillation, not all oscillations are vibrations. The distinction lies in the nature of the restoring force. If the restoring force is due to the elastic properties of the object, it's a vibration. If the restoring force is due to other factors, such as gravity or electromagnetic forces, it's an oscillation. Step 2: Divider

Vibration is the periodic motion and the restoring force is the Force due to elastic property of body. Rigid body can not vibrate. Anything has mass and elasticity can vibrate. ... Oscillation is also Periodic motion and restoring force is due to weight of the body.
