Oscillation refers to a repetitive variation, typically in time, of some measure about a central value, or group of values, with a particular frequency. The term is commonly used in physics and engineering to describe phenomena such as the swinging of a pendulum, the vibration of a spring, or the alternating current in an electrical circuit.

An oscillation is characterized by its amplitude, which is the maximum displacement or value reached from the central position, and its period, which is the time it takes for one complete cycle of the oscillation. The frequency of an oscillation is the number of cycles that occur in a unit of time, usually one second, and is the inverse of the period. Simple harmonic motion is a fundamental type of oscillation where the restoring force is directly proportional to the displacement from the equilibrium position. This type of motion is often used as a model for more complex oscillatory phenomena.

Damping is a phenomenon that causes oscillations to gradually decrease in amplitude over time. This reduction in amplitude is usually due to dissipative forces such as friction or air resistance. If the damping is too strong, the oscillation may not occur at all, and the system will return to its equilibrium position gradually. Resonance occurs when an external force is applied to a system at a frequency close to its natural frequency of oscillation. This can lead to a significant increase in the amplitude of the oscillations.
