Angular velocity is equal to the circumference pi r) times the frequency; if whirling a mass around in a horizontal circle, can find the radius of the circle by (length of string x sinangle), then use the above equation

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…

Essay about physics subject Physics is a broad subject which can cover a lot of physics essay topics; it also involves extensive research work so that one can justify the needs of the physics.

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
