There's more to come!     http://www.answers.com/topic/phase-physics-in-encyclopedia-1 Displacement (s): the total distance that a simple harmonic oscillator moves from its equilibrium point - measured in meters (m). Amplitude (A): the maximum displacement of a simple harmonic oscillator - measured in meters (m) Frequency (f): the number of oscillations per second - measured in Hertz (Hz or s-1) Period (T): the time required for an oscillator to complete one cycle - measured in seconds (s)       *** Let's take a closer look at the relationship between frequency and period. Frequency is measured in cycles per second, whereas period is measured in time per cycle. They are reciprocals of each other! ***   Therefore:  f = 1/T   and    T = 1/f     As previously stated (many times), SHM is based on trigonometric functions. We must investigate these further...
