|
Amplitude |
The maximum displacement from the equilibrium position of an object oscillating around the equilibrium position |
|
|
Anti node |
Location of maximum amplitude and standing waves |
|
|
Beat |
A frequency of the amplitude fluctuations of a wave |
|
|
Constructive Interference |
When 2 waves arrive at the same point exactly in face that is the crests of the 2 waves are precisely aligned as are the troughs |
|
|
Critical damping |
Addition at which the damping of an oscillator causes it to return as quickly as possible to its equilibrium position without oscillating back-and-forth about this position |
|
|
Deformation |
Displacement from equilibrium |
|
|
Destructive interference |
When 2 identical waves arrive at the same point exactly I to face that is precisely aligned crest to trough |
|
|
Elastic potential energy |
Potential energy stored as a result of deformation of an elastic object such as he stretching of a string |
|
|
Force constant |
A constant related to the rigidity of a system: the larger the force constant, the more rigid the system; the force constant is represented by K |
|
|
Frequency |
Number of events per unit of time |
|
|
Fundamental frequency |
The lowest frequency of a periodic way form |
|
|
Intensity |
Power per unit area |
|
|
Longitudinal wave |
Away then which the disturbance is parallel to the direction of propagation |
|
|
Natural frequency |
The frequency at which a system but also late if they were no driving and no damping forces |
|
|
Nodes |
The points where the string does not move; more generally, nodes are where the wave disturbances 0 in a standing wave |
|
|
Oscillate |
Moving back-and-forth regularly between 2 points |
|
|
Over damping |
The condition in which damping of an oscillator causes it to return To equilibrium without oscillating. Oscillator moves more slowly toward equal Librium then in the critically damped system |
|
|
Overtones |
Multiples of the fundamental frequency of the sound |
|
|
Period |
Time it takes to complete one oscillation |
|
|
Periodic Motion |
Motion that requires itself as regular time intervals |
|
|
Resonance |
The phenomenon a driving a system with a frequency = the system's natural frequency |
|
|
Resonate |
A system being driven at its natural frequency |
|
|
, Restoring force |
Force acting in opposition to the force caused by deformation |
|
|
Simple harmonic motion |
The oscillatory motion in a system where the net force can be described by Hooke's law |
|
|
Simple harmonic Oscillator |
A device that implements hooks law such as a mask that is attached to a Spring with the other end of the Spring being connected to your rigid support such as a wall |
|
|
Simple pendulum |
An object with a small mass suspended from a light wire or string |
|
|
Superposition |
A phenomenon that occurs when 2 or more ways arrive at the same point |
|
|
Transverse wave |
Away from which the disturbance is perpendicular to the direction of propagation |
|
|
Under damping |
The condition in which damping of an oscillator causes it to return to equilibrium with the amplitude gradually decreasing to 0. system returns to equilibrium faster but overshoots in a crosses the equilibrium position one or more times |
|
|
Wave |
A disturbance at moves from its source and carries energy |
|
|
Wave velocity |
The speed at which the disturbance moves also called the propagation velocity of propagation speed |
|
|
Wave length |
The distance between adjacent identical parts of a wave |
