Oscillations topis include: Oscillatory, periodic, and harmonic motions. Oscillations are repetitive variations that occur over time. They can be defined as the periodic change of a measure around a central value or between two or more states.  Some examples of oscillations include: A swinging pendulum Alternating current The up-and-down motion of a spring with a weight  Oscillations can also be described as a regular fluctuation in value, position, or state about a mean value.  In physics, some oscillations create waves. For example, a guitar creates sound waves, and you can make... Show more
