In physics, angular velocity or rotational velocity (ω or Ω), also known as angular frequency vector, is a pseudovector representation of how fast the angular position or orientation of an object changes with time (i.e. how quickly an object rotates or revolves relative to a point or axis). The magnitude of the pseudovector represents the angular speed, the rate at which the object rotates or revolves, and its direction is normal to the instantaneous plane of rotation or angular displacement. The orie… WebIn physics, angular frequency "ω" (also referred to by the terms angular speed, angular rate, and pulsatance) is a scalar measure of rotation rate.It refers to the angular displacement per unit time (for example, in rotation) or the rate of change of the phase of a sinusoidal waveform (for example, in oscillations and waves), or as the rate of change of … ma psychology unettunoWebLinear velocity v, in metres per second, is related to the angular velocity by the radius of curvature R: w = v / R.
