Motion
exists in reference to a certain point
motion
a push or pull that acts on an object
force
a wave of higher amplitude has more of this
energy
a "packet" of light energy
photon
what opposite magnetic forces do
attract
how far something or someone has traveled
distance
a force that results when surfaces of objects rub against each other and oppose motion
friction
the number of complete wave cycles in a given amount of time
frequency
a transverse wave that is composed of both an electrical field and a magnetic field
electromagnetic wave
when a charged object touches another object and charge is transferred
charging by conduction
how far someone or something has traveled, measured in a straight line from the starting point
displacement
energy that is stored as a result of an object's position or shape
potential energy
the distance from one crest to another crest in a wave
wavelength
what light does when it moves from one medium into another
bends (refracts)
a material through which electrons can flow freely
conductor
distance divided by time
speed
the energy an object has due to its motion
kinetic energy
the unit for measuring frequency
hertz
particle and wave
a material's ability to impede the flow of electrons
resistance
speed with direction
velocity
the law that is expressed in the formula f=ma
Newton's Second Law
higher frequency results in what?
higher pitch
what is ROY G BIV?
the colors of visible light in order of decreasing wavelengths
what electricity and magnetism have in common
they result from the movement of charged particles
