Hertz
|
*frequency is measured in hertz
|
|
|
Cycle
|
A cycle is the building block of harmonic motion and has a beginning and an end.
|
|
|
Period
|
The time it takes for one cycle is called the period.
|
|
|
Vibration
|
Motion that repeats itself over and over
|
|
|
Frequency
|
The number of cycles an oscillator makes per second
|
|
|
Amplitude
|
Describes the size of a cycle.
|
|
|
Harmonic motion
|
Swinging motion, back and forth motion that is repeating.
|
|
|
Damping
|
Friction causes damping in an oscillator.
|
|
|
Phase
|
The phase of an oscillator describes where it is int he cycle.
|
|
|
Resonance
|
When the frequency of a periodic force matches the natural frequency of the oscillating system, resonance occurs.
|
|
|
Natural frequency
|
A guitar is tuned by adjusting the natural frequency of the vibration string to match a musical note.
|
|
|
Restoring force
|
The restoring force is a force that always acts to pull an oscillator back toward the center position.
|
