EMS (Electromagnetic
Spectrum)
Final Jeopardy
What is radio, microwave, infrared, visible
spectrum, ultraviolet, x-rays, and gamma
rays?
List the wave types of the
electromagnetic spectrum
from longest to shortest
wavelength.
$200
What is Point A?
This point of the coaster
would have the greatest PE.
$400
What is the KE decreases going from
point B to point C.
This is what happens to the
KE from point B to C.
$600
What is chemical to thermal to chemical
to mechanical?
Trace the energy conversions that
would take place when you use a
charcoal grill to cook a hamburger
that you will eventually eat.
$800
What is PE = mgh which is PE = 5 kg •
9.8 m/s2 • 12 m = 588 Joules ?
A 5 kg cat is stuck on a roof
12 m high. This is the cat’s
energy. (Include units.)
$1000
What is KE = ½ mv2 which is KE = ½ • 25 kg (5
m/s)2 = 312.5 Joules ?
A 25 kg dog is running at a
speed of 5 m/s. This is the
dog’s energy. (Include units.)
$200
What is Newton’s First Law of Motion?
This picture illustrates this
law of motion.
$400
What is 300 N?
If the player on the right is pushing with
300 N of force, the player on the left
pushes with this much force when the ball
does not move.
$600
What is B.? It has the most mass.
Of the following, the one
with the greatest inertia.
A) baseball
B) bowling ball
C) pencil
D) ping-pong ball
E) toothpick
$800
What is as the mass increases the acceleration
decreases? It is an indirect/inverse relationship.
The following graph shows the relationship
between mass and acceleration in terms of
Newton’s 2nd Law. This is the relationship
between these variables.
$1000
What is a = F/m which is a = 250 N ÷ 70
kg = 3.57 m/s2?
This is the rate a swimmer will
accelerate off the wall when she pushes
off the wall with a force of 250 N and
she weighs 70 kg. (Remember the
circle diagram.)
$200
This is the motion of the
object represented in this

What is a solid?
The movie clip from Stand
By Me illustrated that you can
hear sound through this type
of medium the fastest.
$400
What is you can not hear an explosion in
space because sound needs a medium to
travel through?
Star Wars shows the Death Star being
destroyed in a thundering explosion. This
is the reason why the person responsible
for the research on this shot should be
fired.
$600
What is as the wavelength increases (gets
longer), the frequency and energy
decrease and vice versa?
This is the relationship between
wavelength, frequency, and energy.
$800
What is constructive interference?
$1000
What is a straight line?
This is what the resulting wave would
look like when destructive interference
happens.
$200
What are balanced forces?
This is what we call forces that
are equal in size but opposite in
direction.
$400
What is v = d/t which is v = 10 m ÷ 20 s =
0.5 m/s ?
A mail truck takes 20 s to move
between mailboxes that are 10 m
apart. This is the mail truck’s
average speed.
$600
What is friction?
This force acts between two
objects that are in contact
with one another.
$800
What is a = vf – vi ÷ t which is a = 24 m/s
– 4 m/s ÷ 4 s = 5 m/s2?
Riding a bike down a hill,
your speed increases from 4
m/s to 24 m/s in 4 s. This is
your acceleration.
$1000
What is a direct relationship? (As the force
increases, so does the acceleration of the object.)
This graph shows the
relationship between
force and acceleration
of an object according
to Newton’s 2nd Law.
This is the
relationship.
$200
What is radiation?
This is how energy from the
Sun reaches the Earth.
$400
What is conduction?
$600
What is convection?
$800
What is a liquid or a gas?
Convection is likely to occur
in these two phases of matter.
$1000
What is the D in conduction stands for the direct
contact of particles, convection occurs in liquids
and gases, while radiation does not require a
medium?
This is how I taught you to
remember the differences between
the three types of heat transfer.

What is a direct relationship? (As the force increases, so
does the acceleration of the object.)
This graph shows the
relationship between
force and acceleration of
an object according to
Newton’s 2nd Law. This
is the relationship.
