Pendulum | a body so suspended from a fixed point as to move to and fro by the action of gravity and acquired momentum. |
Cycle | any complete round or series of occurrences that repeats or is repeated. |
Frequency | the number of times that a periodic function or vibration repeats itself in a specified time, often 1 second. It is usually measured in hertz ν, f |
Amplitude | the maximum variation from the zero or mean value of a periodically varying quantity |
Period | a rather large interval of time that is meaningful in the life of a person, in history, etc., because of its particular characteristics: |
Oscillator | Electronics. a circuit that produces an alternating output current of a certain frequency determined by the characteristics of the circuit components. |
Damping | a decreasing of the amplitude of an electrical or mechanical wave. |
Linear motion | motion along a straight line, and can therefore be described mathematically using only one spatial dimension. |
Harmonic motion | oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position. |
Hertz | the SI unit of frequency, equal to one cycle per second. |
Phase | a distinct period or stage in a process of change or forming part of something's development. |
