force that acts between
materials that touch as they
move past each other
definitions - $400
friction

resist change in state of
motion

angle to the surface and
opposes gravity

Normal force
definitions - $1000

something moving through air
definitions - $1000
Air resistance
a10a
1st law - 200
Every object continues in a
state of rest, or of motion in
a straight line at constant
speed, unless it is
compelled to change that
state by forces exerted
upon it.
1st law - 200
Newton’s First Law
1st law- 400
A measure of inertia
1st law - 400
Mass
1st law - 600
The force of gravity on an
object
1st law - 600
weight
1st law - $800
A mother finds that her
newborn infant sons weighs
300N, a possible new world
record, calculate the boys
mass.
1st law - 800
30.6 kg
(30 kg okay)
b8a
1st law - 1000
When you compress a
junked car into a cube,
which will change, its mass,
volume, or weight?
1st law - 1000
volume
2nd law - $200
The acceleration produced
by a net force on an object is
directly proportional to the
magnitude of the net force, is
in the same direction as the
net force, and is inversely
proportional to the mass of
the object
2nd law - $200
Newton’s Second Law
2nd law - $400
Sketch and find the resultant
of a 6-N force going left and a
8-N force going up.
2nd law - $400
6-N
8-N
10-N
2nd law - $600
Calculate the acceleration of
a 2000 kg single-engine
airplane just before takeoff
when the thrust of its engine
is 500N.
2nd law - $600
0.25 m/s2
2nd law - $800
A rocket fired from its
launching pad not only
picks up speed but also
accelerates as it goes up,
why? (HINT: about 90% of
the mass initially in a rocket
is fuel)
2nd law - $800
Its mass decreases as fuel
is used up. Therefore, the
same force will accelerate it
more.
2nd law - $1000
A certain force applied to a
2kg mass accelerates the
2
mass at 3 m/s . How much
acceleration will the same
force produce on a 4 kg
mass?
2nd aw - $1000
1.5 m/s2
3rd law- $200
Whenever one object exerts
a force on a second object,
the second object exerts an
equal and opposite force on
the first object.

3rd law- - $200
Newton’s Third Law
3rd law- - $400
When swimming, you
push the water backwardcall this the action force.
What is the reaction
force?
3rd law- - $400
The water pushing you
forward.
Daily Double
Make a Wager
3rd law- The Daily Double
Why can you exert greater force
on the pedals of a bicycle if you
pull up on the handlebars?
3rd law-
Daily Double
Because the handlebars push
down on you, and in turn, the
pedals
3rd law- - $800
If action equals reaction, why
isn’t Earth pulled into orbit
around a communication
satellite?
3rd law- - $800
Because of Earth’s much
greater mass and inertia
3rd law- - $1000
If a bicycle and a massive
truck have a head on
collision, upon which vehicle
is the greater impact force?
Which vehicle undergoes the
greater change in motion?
3rd law- - $1000
The forces are equal but the
bicycle experiences a greater
change in motion
potpourri- $200
1 kilogram time a meter per
second squared is also
equal to this unit
potpourri- - $200
Newton
potpourri- $400

forces acting on an object
potpourri- - $400
Net force
potpourri- - $600
the ratio of the force of
kinetic friction to the normal
force
potpourri- $600
Coefficient of kinetic friction
potpourri- - $800
A bowling ball and a
baseball are both dropped
from the top of a third floor
apartment window, which
will hit the ground first?
Which has the greater force
of gravity on it?
potpourri- - $800
Both hit the ground at the
same time but the
Bowling ball has more force
acting on it
gravity
potpourri- - $1000
The force that opposes the
movement of two surfaces
that are in contact and are
sliding over each other.
potpourri- - $1000
Kinetic friction
Final Jeopardy Category:
The horse and his cart
Make a Wager
Final Jeopardy
A horse is pulling a cart
along a path. How can
the horse pull the cart if
the forces between the
two of them cancel out?
Final Jeopardy
They will move if the force
the horse pushes against
the ground is greater than
the force of friction
