Harmoinic Motion
|
Motion that repreats ex.--a swing
|
|
|
Linear Motion
|
gets from one place to another. ex.-- bike
|
|
|
Period
|
time for one cycle to occur.
period = 1/ f |
|
|
freqency
|
means the number of cycles per second f=1/t
|
|
|
In phase
|
going together
|
|
|
out of phase
|
differnt
|
|
|
restoring force
|
tends to return a system to equilibruim
|
|
|
natural frequency
|
perferred rate of oscillation
|
|
|
resonance
|
occurs when a periodic force has the same frequency as tha natural frequency of the system
|
|
|
damping
|
to describe the graudal loss of amplitude of an oscillator
|
|
|
standing wave
|
a wave that is confirmed in a space
|
|
|
wave
|
osscialltion that travels from one place to another
|
|
|
transverse
|
osscalation perpendicular to direction the wave moves
|
|
|
longitudial
|
same vibrations as the wave moves
|
|
|
crest
|
top of a wave
|
|
|
trough
|
the lowest part
|
|
|
fundametal
|
lowest frequency
|
|
|
harmonics
|
other natural frequecies that a standing wave can occur at
|
|
|
node
|
tip
|
|
|
antinode
|
middle
|
|
|
amplitude
|
max. height. same as half the distance
|
|
|
speed
|
v=F(wavelength)
|
|
|
constructive
|
occurs when waves add up to make a larger amplitude when two sounds waves interfere it gets louder
|
|
|
destructive interference
|
waves add up to make a wave with smaller or zero amplitude ex. noise cancelling headphones
|
|
|
superposition
|
total vibration is sum of all virbrations
|
|
|
reflection
|
the wave bounces and goes in a new direction
|
|
|
refraction
|
the wave bends as it passes into and though an object. (glasses)
|
|
|
diffraction
|
the wave bends around the object or thought holes (someone talking with door open)
|
|
|
absorption
|
the wave is abosorped ( theater curtain are really heavy)
|
|
|
wave front
|
the crests of a plane wave( straghit) for a pattern of a parrel straghit lines
|
|
|
propagate
|
waves spread from where they begin
|
|
|
medium
|
what it goes through. (the paper was the medium in that one lab)
|
