Forced oscillation (driven oscillation): if apply a periodically varying driving force with angular frequency to a damped harmonic oscillator; the angular frequency with which the mass oscillates is equal to the driving angular frequency; if we force the oscillator to vibrate w/ angular freq nearly equal to angular frequency: it is naturally disposed to oscillate at a certain freq, so we expect the amplitude to be larger than when the 2 are very different; little damp: sharp A peak when…

Power and rotational speed[edit] The maximum power of a Savonius rotor is given by P_{\mathrm{max}} = 0.36\, \mathrm{kg\, m^{-3}} \cdot h \cdot r \cdot v^3, where h and r are the height and radius of the rotor and v is the wind speed.[citation needed] The angular frequency of a rotor is given by \omega = \frac{\lambda \cdot v}{r}, where \lambda is called the tip-speed ratio. The range λ varies within is characteristic of a specific windmill, and for a Savonius rotor λ is typically around…

Understand and use the terms amplitude, period, frequency, angular frequency and phase difference and express the period in terms of both frequency and angular frequency.

Plank's constant has the dimension of: #Momentum #Energy #Angular #Frequency

Wave pulse: ex: transverse wave on a stretched string; pulse travels along length of string; tension in string restores the straight line shape; periodic wave: repetitive motion; each particle in string undergoes periodic motion as the wave propagates; simple harmonic motion: angular frequency = 2pi x f; period T=1/f = 2pi/angular frequency; symmetrical sequence of crests and troughs: sinusoidal waves: every particle has the same frequency
