This is the tool you can use to
measure force on an object.
A 100
What is a spring scale?
A 100
This is the type of friction
that makes starting to
pushing a box across the floor
difficult.
A 200
What is static friction?
A 200
This is the surface of the ones
listed here: grass, carpet, tile
floor, or sandy path, that will
most likely allow a basketball
to roll the farthest.
A 300
What is a tile floor?
A 300
This is what happens to an
object when balanced forces
are acting on it.
A 400
What is the object does not
move?
A 400
This is what happens to an
object when unbalanced
forces are acting on it.
A 500
What is the object moves in
the direction of the net force?
A 500
Of the places listed below,
this is where there will be the
greatest affect of gravity.
In an airplane, at sea level, on
the Moon, on Mount Everest
B 100
What is at sea level?
B 100
The gravitational pull of this
object keeps the Moon from
shooting straight out into
outer space.
B 200
What is the Earth?
B 200
This is the object that causes
changes in the daily tides
because of its gravitational
pull on Earth.
B 300
What is the Moon?
B 300
An object with a large mass
will have a _________
gravitational force.
B 400
What is strong?
B 400
Since the gravitational force
of Mr. Schmidt is less than
the gravitational force of the
Earth, this is what happens.
B 500
What is we are not pulled
toward Mr. Schmidt even
though he has a gravitational
force?
B 500
This is what is measured
which gives us the difference
between a speed and a
velocity.
C 100
What is a direction?
C 100
Based on this graph, this is
what is happening between 3
seconds and 7 seconds.
C 200
What is the object is changing
acceleration?
C 200
This is the thing an observer
uses to detect motion.
C 300
What is a frame of reference?
C 300
DAILY
Place A Wager
DOUBLE
C 400
This is the average speed of a
runner who is traveling 3
kilometers in 30 minutes.
Please tell you speed in
km/hr.
C 400
What is 6 km/hr?
C 400
This is one of the kinds of
motion mentioned in the text.
C 500
What is: (accept any one of
these) circular motion,
straight-line motion, or
vibrational motion?
C 500
This is what causes a rock to
sit on the ground and remain
in the same place unless a
force acts on it.
D 100
What is inertia?
D 100
This is a measure of the force
needed to stop a moving
object.
D 200
What is momentum?
D 200
A billiard ball strikes another
ball and slows down while
causing the second ball to
move. This is what was
given to the second billiard
ball when the first one struck
the second one.
D 300
What is momentum?
D 300
Imagine you are pushing a
10-kilogram box with a 5-N
force and want to find the
acceleration. This is the
equation you would use to
calculate your acceleration.
D 400
What is acceleration = force /
mass?
D 400
A baseball player hits the ball
with his bat. The baseball
hits the bat with an opposite
and ____________ force.
D 500
What is equal?
D 500
This is Newton’s First Law of
Motion
E 100
What is: An object at rest
remains at rest, and an objet
in motion remains in motion
at constant speed and in a
straight line, unless acted on
by an unbalanced force?
E 100
According to Newton’s 2nd
Law, of the objects listed
below, this one will have the
greatest acceleration if
thrown with the same amount
of force.
Baseball, tennis ball, bowling
ball, table tennis ball
E 200
What is a table tennis ball?
E 200
This is Newton’s Third Law
of Motion.
E 300
What is: When a force is
applied to an object, the
object exerts an equal force in
the opposite direction?
E 300
This is the example below where
there would be no movement.
A 2-N force pulling up and a 5-N force pushing down
A 2-N force pulling up and a 3-N force pushing down
A 3-N force pulling to the left and a 3-N force pulling to the right
A 5-N force pulling to the left and a 4-N force pulling to the right
E 400
What is: A 3-N force pulling to
the left and a 3-N force pulling to
the right?
E 400
This is Newton’s Second Law
of Motion
E 500
What is: The acceleration of
an object depends on the
mass of the object and the
size of the net force applied?
E 500
These are the two things you
should describe about a force
that acts on an object.
F 100
What are the size and the
direction of the force?
F 100
This is how balanced forces
affect the motion of an object.
F 200
What is there is no change in
motion when forces are
balanced?
F 200
This is the net force on a ball
that has a 15-N force pushing
right and a 9-N force pushing
left.
F 300
What is 6-N to the right?
F 300
This is an example of static
friction.
F 400
What is pushing against a
heavy piano?
F 400
This is why most coastal
areas have two high tides
each day.
F 500
What is the Earth rotates and
there are two areas of high
tide on the Earth so any area
passes through each of these
high tide areas?
F 500
The Final Jeopardy Category is:
Speed
Please record your wager.
Click on screen to begin
This is the difference between
instantaneous speed and average
speed.
Click on screen to continue
What is instantaneous speed is the
speed at a certain moment and
average speed is the average of
the instantaneous speeds over a
certain period of time?
