oscillation


oscillationOscillation of a clock pendulum takes it from point a to point b and back to a. The dashed red line is the position of the pendulum at rest.

oscillation

(ˌɒsɪˈleɪʃən) n1. (General Physics) physics statistics a. regular fluctuation in value, position, or state about a mean value, such as the variation in an alternating current or the regular swinging of a pendulumb. a single cycle of such a fluctuation2. the act or process of oscillating oscillatory adj

os•cil•la•tion

(ˌɒs əˈleɪ ʃən)

n. 1. an act or instance of oscillating. 2. a. a single swing in one direction of an oscillating body. b. a single fluctuation between the maximum and minimum values of an oscillatory cycle. [1650–60; < Latin] os′cil•la•to`ry (-ləˌtɔr i, -ˌtoʊr i) adj.
oscillationThe time it takes the pendulum to swing from a to b and back to a is known as its period. The dashed red line from the central point represents the position of the pendulum at rest.

os·cil·la·tion

(ŏs′ə-lā′shən)1. A steady, uninterrupted, backward and forward swinging about a central point. Compare vibration.2. A single cycle of motion about a central position.

oscillation

oscillation


Oscillation

Any effect that varies in a back-and-forth or reciprocating manner. Examples of oscillation include the variations of pressure in a sound wave and the fluctuations in a mathematical function whose value repeatedly alternates above and below some mean value.

The term oscillation is for most purposes synonymous with vibration, although the latter sometimes implies primarily a mechanical motion. The alternating current and the associated electric and magnetic fields are referred to as electric (or electromagnetic) oscillations.

If a system is set into oscillation by some initial disturbance and then left alone, the effect is called a free oscillation. A forced oscillation is one in which the oscillation is in response to a steadily applied periodic disturbance.

Any oscillation that continually decreases in amplitude, usually because the oscillating system is sending out energy, is spoken of as a damped oscillation. An oscillation that maintains a steady amplitude, usually because of an outside source of energy, is undamped. See Anharmonic oscillator, Damping, Forced oscillation, Harmonic oscillator, Vibration

oscillation

[‚äs·ə′lā·shən] (control systems) cycling (mathematics) The oscillation of a real-valued function on an interval is the difference between its least upper bound and greatest lower bound there. The oscillation of a real-valued function at a point x is the limit of the oscillation of the function on the interval [x-e, x + e ] as e approaches 0. Also known as saltus. (physics) Any effect that varies periodically back and forth between two values.
