1. Kinetic energy-
 
The energy that an object has because of its
motion
 
2. Potential energy-
 
Energy that is stored in an object
 
1.
Energy that is 
stored
 in an object is 
potential
energy
.
2.
The energy of 
motion
 is 
kinetic
 energy.
3.
Electrical
 energy can be used to 
run appliances
.
4.
Chemical energy
 is energy that is 
stored inside
matter
 (a form of potential energy).
5.
Mechanical energy
 is energy an object has due to its
motion
 (a form of kinetic energy).
6.
Light energy
 is energy that 
can be seen
.
7.
Sound energy
 is energy that 
can be heard
.
8.
Thermal energy
 is energy from 
heat
.
 
3. reflection-
 
Occurs when light waves
bounce off a surface
 
4. refraction-
 
Occurs when light waves bend as they
pass from one material to another
 
2. prism-
 
A substance that separates white light
into colors
 
1. light-
 
A form a energy that can be
seen and travels in waves
 
1.
Light
 is a form of 
energy
 that you can
see
 and 
travels in waves.
2.
The 
high point
 of a 
wave
 is called a
crest
.
3.
The 
low point
 of a 
wave
 is called a
trough
.
4.
The 
distance from one crest to the next
crest
 is called the 
wavelength
.
 
1.
Reflection-
 when light waves 
bounce
 off
a surface
2.
Refraction-
 when light waves pass
through an object and are 
bent
 as they
go through
3.
Absorption
-when light waves are 
taken
into an object
4.
Transmission-
 when light waves 
pass
through
 an object
 
1.
The 
color of an object
 depends on the
color of light that it reflects
.
2.
White light
 is made up of 
all the colors
of the rainbow.
3.
ROY G. BIV
- colors of the rainbow in
order from the 
longest to the shortest
wavelength
.
 
3. volume-
 
The amplitude, or loudness, of
a sound
 
4. pitch-
 
How high or low a sound seems
to a listener
 
2. vibration-
 
Very fast back and forth
movement of matter
 
1. sound-
 
A form of energy produced by
vibrations
 
 
1.
Sound
 is 
produced by vibrations
 of matter. When a
material vibrates
, it 
creates sound waves.
 
2.
The 
energy
 of the sound wave and the 
distance
 the
vibration object is 
from the listener
 are 
2 factors
that 
determine 
the 
volume
 of the sound.
 
3.
Frequency
 is the 
number
 of 
crests
 and 
troughs
produced in a given amount of time. Frequency
determines pitch
.
 
 
 
1.
Outer ear
- 
part
 of the ear 
you can see
; 
gathers
sound waves
 from the air and 
funnels them
 to the
eardrum.
2.
Eardrum-
 thin 
flap of skin
 that 
vibrates
 when sound
waves hit it.
3.
Middle ear
- contains 
3 tiny bones
 that 
pick up
vibrations
 from the eardrum.
4.
Inner ear-
 has 
coiled tubes filled with fluid
 that
vibrate
 causing 
nerve cells
 to 
send signals
 to the
brain.
 
2. convection-
 
The transfer of thermal energy
by the movement of fluids
 
1. conduction-
 
The transfer of thermal energy
from particle to particle between
two objects that are touching
 
6. Thermal energy-
 
The kinetic energy of moving
particles  of matter
 
3. heat-
 
A measure of how much thermal
energy is transferred from a warmer
substance to a cooler substance
 
5. temperature-
 
The average kinetic energy of
the particles of a substance
 
4. radiation-
 
The transfer of thermal energy
without matter
 
 
1.
Thermal energy
 is the 
kinetic energy
 of 
tiny moving particles
of matter.
2.
The 
hotter
 a substance is, the 
faster
 its particles move. The
colder
 the substance, the 
slower
 its particles move.
3.
Heat
 is a measure of how much 
thermal energy
 is
transferred
 from one substance to another.
4.
Thermal energy
 is 
transferred by conduction, convection, or
radiation
.
5.
In 
conduction
, 
2 objects
 need to 
touch
 in order to share
thermal energy (ex- hot stove touching a pan).
6.
In 
convection
, thermal energy is transferred in 
liquids and
gases
 (warm air rises, cooler air sinks).
7.
In 
radiation
, thermal energy is transferred by 
waves without
matter
 (ex- heat from the sun travels through space to
Earth).

  19. Lesson 14.3 Notes Sound 1. Sound is produced by vibrations of matter. When a material vibrates, it creates sound waves. 2. The energy of the sound wave and the distance the vibration object is from the listener are 2 factors that determine the volume of the sound. 3. Frequency is the number of crests and troughs produced in a given amount of time. Frequency determines pitch.

Inner ear- has coiled tubes filled with fluid that vibrate causing nerve cells to send signals to the brain.

  27. 4. radiation- The transfer of thermal energy without matter

  28. Lesson 14.4 Notes Thermal Energy 1. Thermal energy is the kinetic energy of tiny moving particles of matter. The hotter a substance is, the faster its particles move. The colder the substance, the slower its particles move. Heat is a measure of how much thermal energy is transferred from one substance to another. Thermal energy is transferred by conduction, convection, or radiation. In conduction, 2 objects need to touch in order to share thermal energy (ex- hot stove touching a pan). In convection, thermal energy is transferred in liquids and gases (warm air rises, cooler air sinks). In radiation, thermal energy is transferred by waves without matter (ex- heat from the sun travels through space to Earth). 2. 3. 4. 5. 6. 7.
