Potential energy
C 100
What does the Law of
Conservation of Energy state?
C 200
Energy can not be created nor
destroyed, it changes forms.
C 200

Potential energy depending
upon the object’s height
above the earth’s surface
C 400
What is the SI unit of
measurement for energy?
C 500
Joules, J
C 500
Define force.
D 100
A force is a push or a pull
D 100
What does a force give off?
D 200
Energy
D 200
What is the unit for force?
D 300
Newton, N
D 300
What is the formula force?
D 400
F=ma
D 400
What is the difference
between balanced and
unbalanced forces?
D 500
Balanced forces do not
change the motion of the
object, while unbalanced
forces do.
D 500
What is acceleration?
E 100
The rate of change in velocity
over a period of time.
E 100

backstroke at a velocity of
20meters per minute
upstream. The current
flowing against her at a rate
of 5 meters per minute.

Brady’s guinea pigs, raced
across the 6 meter kitchen
floor. Stanley made it in 4
seconds and Zoe took 8
seconds. Calculate their
average speed.

acceleration?
E 400
A= vf - vi
time
E 400

skateboarder who is stopped
at a red light and then
accelerates to reach a speed
of 45 m/s in 9 seconds?
E 500
A= 45 m/s - 0 m/s
9s
A= 5 m/s2
E 500
State Newton’s First Law
F 100
An object at rest will remain
at rest and an object in
motion will remain in motion
at a constant velocity until
acted upon by a net force.
F 100
What is inertia?
F 200
The tendency of an object to
resist any change in motion.
F 200
What is the formula used to
describe Newton’s Second
Law?
F 300
Force = mass * acceleration
F 300
Newton’s Third Law describes
what kind of forces?
F 400
Action-Reaction forces
F 400
Describe the action force of
an untied, inflated balloon
when it is released.
F 500
The action force is the air
escaping from the balloon.
The reaction force is the
balloon flying in the opposite
direction.
F 500
The Final Jeopardy Category is:
“Circular Motion”
Please record your wager.
Click on screen to begin
Describe whether or not the Moon‘s
velocity is constant, if the Moon were
to travel at a constant speed in a
circular orbit around the Earth.
Click on screen to continue
The Moon’s velocity is not
constant, because it is changing
direction while orbiting
eventhough it is traveling at a
constant speed.
