Cycle | any complete round or series of occurrences that repeats or is repeated. |
Frequency | the number of periods or regularly occurring events of any given kind in unit of time, usually in one second. |
Amplitude | the absolute value of the maximum displacement from a zero value during one period of an oscillation. |
Period | a round of time marked by the recurrence of some phenomenon or occupied by some recurring process or action. |
Oscillator | a circuit that produces an alternating output current of a certain frequency determined by the characteristics of the circuit components. |
Damping | The decrease of amplitude of an electrical or mechanical wave |
Linear Motion | Is a motion along a straight line |
Harmonic Motion | periodic motion consisting of one or more vibratory motions that are symmetric about a region of equilibrium, as the motion of a vibrating string of a musical instrument. |
Hertz | the standard unit of frequency in the International System of Units (SI), equal to one cycle per second. |
Phase | a particular stage or point of advancement in a cycle; the fractional part of the period through which the time has advanced, measured from some arbitrary origin often expressed as an angle (phase angle) the entire period being taken as 360°. |
