How is angular frequency related to time?
How is angular frequency related to time? It is the reciprocal of the period and can be calculated with the equation f=1/T. Some motion is best characterized by the angular frequency (ω). The angular frequency refers to the angular displacement per unit time and is calculated from the frequency with the equation ω=2πf. What does […]
