is created when something
vibrates, sending waves through the
air or other materials.
Sound
Sound travels through
different mediums as__________(Perpendicular to the direction)
transverse waves.
Sound travels through
different mediums as
_______________
The particles of the medium
move back and forth parallel
to the direction the wave is
travelling.
longitudinal waves.
Sound travels through
different mediums as
_____________
The particles travel in
circular motion.
surface.
This movement creates areas of
___________ where particles
are closer together,
compression,
and
_____________, where they are
spread apart.
rarefaction
Energy is the ability to do
work.
Potential Energy formula
PE=mgh
Kinetic Energy formula
KE=1/2mv squared
The Law of Conservation of Energy
Energy can neither be created nor destroyed.
It can be transferred to another object or
converted into a different form.
The amount of energy stays the same.
is a type of motion that allows an object to follow a
circular path while maintaining a constant speed.
Uniform Circular
Motion
also known as center-
seeking force, comes from the word “centri”
which means center
Centripetal force,
centripetal force formula
F=mvsquared/r
cantripetal acceleration formula
a= v squared/r
amount oftime needed to
complete one revolution orrotation; measured
in second (s)
Period -the
number ofrotation orrevolution
per unittime; measured in hertz (Hz) or
revolution per second (rev/s)
Frequency -
work formula
w=fd
work with angle formula
fcos0d
is a measure
of how hot or cold
something is.
Temperature
particle movement hot
fast
pRTICLE MOVEMENT COLD
Slow
So the formula for the speed of the sound and
temperature is expressed as:
v= 331 m/s + (0.6m/s°C) T
