What do we call velocity that
does not change?
A 100
It is called constant velocity.
A 100
Why is velocity is a vector
quantity?
A 200
Velocity has both magnitude
and direction.
A 200
What causes a change in
acceleration?
A 300
A change in magnitude or
direction.
A 300
What are the common SI
units of acceleration?
A 400
m/s2 (meters per second per
second)
A 400
If the sign of velocity is
negative, and the sign on
acceleration is positive, is the
object slowing or increasing
its speed?
A 500
It is slowing down.
A 500
How is a scalar different from
a vector quantity?
B 100
A vector quantity has both
magnitude and direction,
while a scalar has only
magnitude.
B 100
What is the term refers to the
total length of an object’s
movement?
B 200
Distance
B 200
What results from the
addition of vectors?
B 300
A resultant.
B 300
What term is refers to the
shortest distance between
initial and final positions?
B 400
Displacement
B 400
Which of these is not a vector
quantity?
momentum, centripetal force,
mass, or work
B 500
Mass

What scientist experimented
with and conducted “thought
experiments” on falling
bodies.
C 100
Galileo
C 100
Two object of different
masses, falling near the
earth’s surface in a vacuum,
should accelerate to earth at
what rate?
C 200
Both should acceleration to
Earth at approximately 9.8
m/s2
C 200
What factors could affect the
rate an object accelerates
through the earth’s
atmosphere?
C 300
Air Resistance and shape of
the object.
C 300
DAILY
Don’t Place A Wager
DOUBLE
C 400
What is the relationship
between time, g, and the
distance fallen by a freelyfalling object?
C 400
Distance increases
proportionally with the square
of time (distance fallen = ½ gt2)
C 400
What are astronauts on the
International Space Station
weightless?
C 500
They are in a constant state of
free fall because they are in
orbit.
C 500
If a plane flying 200 miles/hr
drops a package, neglecting
air resistance, where will the
plane be in relation to the
package when it hits the
ground?
D 100
Directly over the package.
D 100
Neglecting air resistance,
what is the only force that
acts on a projectile once it is
launched?
D 200
Gravity
D 200
One a projectile is launched,
what allows it to continue its
forward motion before it hits
the ground?
D 300
Its own inertia.
D 300
Neglecting air resistance, the
path of a projectile has what
shape?
D 400
What is parabolic?
D 400
Which of the following
demonstrates projectile
motion?
A punted football, a cannon
ball shot from a cannon, a
baseball thrown straight up
into the air, a water droplet
from a sprinkler head.
D 500
The baseball thrown straight
up into the air.
D 500
What is Newton’s First law of
motion?
E 100
A body naturally tends to continue
in whatever state of motion or rest
and tends to resist any changes.
An object at rest tends to stay at
rest. An object in motion tends to
stay in motion (unless an
unbalanced force acts on it).
E 100
What property of matter
refers to resistance to a
change in motion?
E 200
Inertia
E 200
What equation can represent
Newton’s second law of
motion?
E 300
F = ma
E 300
What is the relationship
between force and
acceleration according to
Newton’s second law?
E 400
They are directly proportional
(The larger the force, the
greater the acceleration.)
E 400
What is Newton’s third law
or Motion?
E 500
When an object exerts a force on
a second object, the second
objects exerts a force on the first
that is equal in size and in the
opposite direction.
(“To every action, there is an
equal and opposite reaction.”)
E 500
Where on the graph below is
there constant velocity?
F 100
(b)
F 100
A Newton-meter is
equivalent to what unit of
work or energy?
F 200
The Joule
F 200
Power may be defined
by what relationship?
F 300
Power = work/time
(the rate at which work is
done)
F 300
What is the unit of Power?
F 400
The Watt
F 400
What law states that energy is
not created or destroyed, but
converted from one form to
another?
F 500
The Law of Conservation of
Energy.
F 500
The Final Jeopardy Category is:
Simple Machines
Please record your wager.

How does a simple machine
make work easier?
Click on screen to continue
A simple machine can increase the amount
of effort force applied to the machine. It
can do this by increasing the distance that
the effort force is applied (such as using a
long lever to pry a heavy object).
