Tnet=
Ia
L=
Iw
define simple pendulum
mass on string oscillating due to force of gravity with mechanical energy being converted between KE and GPE
define simple harmonic motion
specific oscillatory motion where a restoring force acts on an object in an opposite direction
define wave
flow of energy through space and time
define transverse
oscillations are perpendicular to velocity of wave
define longitudinal
oscillations are parallel to velocity of wave
define mechanical
needs material to move energy
define electromagnetic
does not need material to move energy
define wavelength
distance between adjacent peaks or troughs
define amplitude
height of a wave measured from the middle
define frequency
how quickly the energy oscillates
define period
time for one complete cycle
define wave interference
wave addition/subtraction which causes super imposing
v=
sqrt t/u
define resonance
phenomenon based on the hertz that are in tune with parameters
define standing waves
clear and observable on strings
define nodes
point where string does not move
