Question

(1) angular frequecy

Answer 1

angular frequency ω is a scalar measure of rotation rate. It refers to the angular displacement per unit time or the rate of change of the phase of a sinusoidal waveform, or as the rate of change of the argument of the sine function.

Answer 2

Angular frequency (ω), also known as radial or circular frequency, measures angular displacement per unit time. Its units are therefore degrees (or radians) per second. Hence, 1 Hz ≈ 6.28 rad/sec. Since 2π radians = 360°, 1 radian ≈ 57.3°.
