Friction $100
This is the direction in which
friction affects an object.
What is the opposite direction?
Friction $200
These are the three types of
friction.
What are sliding friction, rolling
friction and fluid friction?
Friction $300
This is a type of fluid friction that
is exerted on objects falling
through the air.
What is air resistance?
Friction $400
These are the two factors that
affect the magnitude of friction.
What are the types of surfaces and
how hard they push together?
Friction $500
Make up a scenario in which the
amount of friction on an object is
reduced.
Examples include adding oil (ie. To a
an engine), adding wheels (ie.
Wheels on your shoes), polishing a
surface, reducing the amount of
contact between two objects.
Gravity $100
You would weigh less in this
location than in Galveston due to
the earth’s gravitation pull.
HINT: multiple answers are
acceptable
Multiple Questions acceptable
Gravity $200
This occurs when the only force
acting on an object is gravity.
What is free fall?
Gravity $300
The larger the object, the ______
its gravitational pull.
HINT: The earth vs. people
What is larger?
Gravity $400
This law states that the force of
gravity acts between all objects in
the universe.
What is the law of Universal
Gravitation?
Gravity $500
This is the force of gravity on a
person or object at the surface of
a planet.
What is weight?
Newton’s Laws $100
This is the formula for force, as
stated in Newton’s Second Law.
What is
Force = Mass x Acceleration?
Newton’s Laws $200
This law states that for every
action there is an equal and
opposite reaction.
What is Newton’s Third Law?
Newton’s Laws $300
This is another name for
Newton’s First Law, which states
that an object at rest remains at
rest and an object in motion
remains in motion unless acted
upon by an unbalanced force.
What is the law of inertia?
Newton’s Laws $400
If two people on skateboards
push against each other, which
person will accelerate faster?
Who is the person with less mass?
Newton’s Laws $500
These are the two ways that
acceleration can be increased.
What are increasing the force or
decreasing the mass of the object?
Momentum $100
The larger the mass the
_________ the momentum.
What is greater?
Momentum $200
In the following example, this
object has more momentum: a 90
lb. person moving at 1 m/s or a
90 lb. dog moving at 2 m/s.
What is the 90 lb. dog?
Momentum $300
This is the formula for
momentum.
What is
momentum = mass x velocity
(p = mv)?
Momentum $400
If there is no friction, this is the
change in the total momentum of
the system when two object
collide.
What is no change?
Momentum $500
This is the momentum of a 5 kg
bowling ball moving at 10 m/s.
(HINT: Remember the formula for
momentum)
What is 50 kg*m/s?
Solution:
Momentum = mass x velocity
Mass = 5 kg
Velocity= 10 m/s
Momentum = 5 kg x 10 m/s
Momentum = 50 kg*m/s
Forces $100
This is a push or a pull.
What is a force?
Forces $200
These are forces that are opposite in
direction and equal in size.
What are balanced forces?
Forces $300
This is the force that a surface exerts
on another when rubbing against each
other.
What is friction?
Forces $400
This is how you would find the net
force acting on the car below.
What is add the forces together?
Forces $500
This is the direction that the object
below will move.
What is to the west?
