|
Linear Motion
|
A motion that goes from one place to another without repeating.
|
|
|
Harmonic Motion
|
Motion that repeats in cycles.
|
|
|
Cycle
|
A unit of motion that repeats.
|
|
|
Pendulum
|
A device that swings back and forth due to the force of gravity.
|
|
|
Oscillator
|
A physical system that has repeating cycles.
|
|
|
Restoring Force
|
Any force that always acts to pull a system back toward equilibrium.
|
|
|
Period
|
The time it takes for each complete cycle.
|
|
|
Frequency
|
How often something repeats, expressed in hertz.
|
|
|
Hertz
|
The unit of frequency. One hertz is 1 cycle per second.
|
|
|
Amplitude
|
the amount that a cycle moves away from equilibrium.
|
|
|
Natural Frequency
|
The frequency at which a system oscillates when disturbed.
|
|
|
Periodic Force
|
A repetitive froce.
|
|
|
Resonance
|
An exceptionally large amplitude that develops when a periodic force is applied at the natural frequency.
|
|
|
Wave
|
A traveling oscillation that has properties of frequency, wavelength, and amplitude
|
|
|
Wavelength
|
The distance from any point on a wave to the same point on the next cycle of the wave.
|
|
|
Transverse
|
A wave is transverse if its oscillations are not in the direction it moves.
|
|
|
Longitudinal
|
A wave is longitudinal if its oscillations are in the direction it moves.
|
|
|
Constructive interference
|
When waves add up to make a larger amplitude.
|
|
|
Destructive interference
|
When waves add up to make a smaller, or zero, amplitude.
|
|
|
Pitch
|
The perception of high or low that you hear at different frequencies of sound.
|
|
|
Decibel
|
Measure of the loudness (amplitude) of sound.
|
|
|
Supersonic
|
Faster than the speed of sound.
|
|
|
Doppler Effect
|
An increase or decreasse in frequency caused by the motion of a source of sound.
