Simple Harmonic Motion and Wave Motion

 P: 10 Hi, I was wondering if anyone could explain Simple Harmonic Motion. My physics teacher has tried and I have read the parts in the book, but I am still confused. I know how to find the amplitude from the standard form equations, but I really just don't understand how to get the period and the frequencies. Does it have something to do with the $$\omega$$t+$$\phi$$ thing or am I just way off? (If it doesn't, please explain what $$\omega$$t+$$\phi$$ tells you.) Thank you! -- Commodore
 Admin P: 21,585 For a sinusoidal (sin or cos) wave, the parameter $\omega$ is the angular velocity and multiplied by t gives an angular position which is linear with time - $\omega$t is always increasing. The other parameter in the argument, $\phi$, is the phase angle, which simply shifts the sine wave in time. See if this helps - http://hyperphysics.phy-astr.gsu.edu/hbase/shm.html
 P: 10 Thank you very much for the information. I am about to see if I understand it by taking my last test (before the final).
