Notice that the coefficient of the displacement term, km, is the square of angular frequency, which is given by the equation ω=(km), and it is customary to rewrite this coefficient as km=ω02 where the subscript means that this represents the initial angular frequency. The final piece of...
Ans: The formula for time is T= 1/f How angular frequency measures? Ans: Angular frequency measures angular displacement per unit time. What does a simple pendulum consist of? Ans: A simple pendulum consists of a heavy point mass called the bob, attached to an inextensible string which ...
This also gives the frequency of the wave in Hertz. If the angular velocity is known, then the frequency can be calculated by using the equation f=ω2π, where ω is the angular velocity. The units for frequency calculated from this equation will be radians /second....
