Our Word of the Year 'pandemic,' plus 11 more. Oscillation refers to the repeated back and forth movement of something between two positions or states. The length of the pendulum is the main thing that controls the frequency. North Atlantic Oscillation (NAO), an irregular fluctuation of atmospheric pressure over the North Atlantic Ocean that has a strong effect on winter weather in Europe, Greenland, northeastern North America, North Africa, and northern Asia.The NAO can occur on a yearly basis, or the fluctuations can take place decades apart. 'Nip it in the butt' or 'Nip it in the bud'? It is important to understand that every oscillatory motion is periodic motion but every periodic motion is not oscillatory. The Oscillation swinging side by side of a pendulum Spring's Oscillation Up and down Oscillation . an act or instance of oscillating. Which word describes a musical performance marked by the absence of instrumental accompaniment. An oscillating movement occurs around an equilibrium point or mean value. At the top of the swing, potential energy is at maximum, and that energy is converted to kinetic energy as it falls and is driven back up the other side. ( ˌɒsɪˈleɪʃən) n. 1. Learn a new word every day. Andrew Zimmerman Jones is a science writer, educator, and researcher. oscillation: [ os″ĭ-la´shun ] a backward and forward motion, like that of a pendulum; also vibration, fluctuation, or variation. Let that natural frequency be denoted by ωn ω n. But the amplitude of the oscillation decreases continuously and the oscillation stops after some time. The motion of a simple harmonic oscillating system—when the restoring force is directly proportional to that of the displacement and acts in the direction opposite to that of displacement—can be described using sine and cosine functions. These example sentences are selected automatically from various online news sources to reflect current usage of the word 'oscillation.' Oscillation Basics One of the most commonly used oscillators is the pendulum of a clock. He is the co-author of "String Theory for Dummies.
