Angular frequency, measured in radians per second or Hertz, is a fundamental property that describes the rate of rotation or oscillation around a central axis. It is related to angular velocity (measured in radians per second) and period (measured in seconds), with angular frequency being equal to 2π divided by the period. Angular frequency units are essential for describing a wide range of phenomena, including circular motion in physics, rotating machinery in engineering, sound waves in acoustics, musical tempo, and heart rate in medicine.
