Pendulum | A mass hung from a fixed support so that it is able to swing freely under the influence of gravity. Since the motion of pendulums is regular and periodic, they are often used to regulate the action of various devices, especially clocks. |
cycle | a sequence of changing states that, upon completion, produces a final state identical to the original one. |
Frequency | he 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 | recurring at equal intervals of time. |
Oscillator | a device or machine producing oscillations. |
Damping | a decreasing of the amplitude of an electrical or mechanical wave. |
Linear motion | is 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 | the fraction of a cycle of a periodic quantity that has been completed at a specific reference time, expressed as an angle |
