Speed of an object
in a particular
direction
What is velocity?
Game Board
A change in a
moving object’s
speed or direction
What is
acceleration?
Game Board
An object that
appears to stay in
place to help you
detect the motion
of another object
What is a reference
point?
Game Board
final velocity – starting velocity
time it takes to change
What is the
formula for
acceleration?
Game Board
The formula for
speed
What is:
Speed = distance
time
Game Board
A push or a pull on
an object.
What is a force?
Game Board
The total force
after all forces
have been added
together.
If the question is correct--Bonus!!!!! (100pts)
What is net force?
Game Board
The net force when
an object is being
pushed with 10N to
the right, and pulled
with 5N to the right
What is 15N to the
right?
Game Board
This can cause an
object’s motion to
change speed
and/or direction
What is an
unbalanced force?
Game Board
When the net force
is anything but 0N
this type of force is
present.
What is an
unbalanced force?
Game Board
This force always
opposes motion
What is friction?
Game Board
This opposing force
keeps an object
staying still even
though it is being
pushed or pulled
What is static
friction?
Game Board
While an object is
moving, the
frictional force is
referred to as
What is kinetic
friction?
Game Board
A piano on wheels
experiences this
type of friction
What is rolling
kinetic friction?
Game Board
This type of friction
occurs when a
liquid or gas is
used, possibly to
reduce friction
What is fluid
kinetic friction?
Game Board
The force of
attraction between
objects
What is gravity?
Game Board
The measure of
gravitational force
exerted on an
object
What is weight?
Game Board
A measure of the
amount of matter in
an object. It does
not change when an
objects’ location
changes
What is mass?
Game Board
According to Newton’s
Law of Universal
Gravitation, the
gravitational pull is
greater between objects
that …
What is have more
mass or are closer
together?
Game Board
He came up with
the Law of
Universal
Gravitation
Who is Sir Isaac
Newton?
Game Board
This states that
gravitational force
is related to mass
and distance.
What is the law of
universal
gravitation?
Game Board
A runner traveling at
6 m/s South slows to a
stop at the base of a
hill after 4 s. What is
the runner’s
acceleration?
Game Board
This force is caused
by the rubbing
together of
microscopic hills
and valleys of
objects.
What is friction?
Game Board
A swimmers velocity
changes from 10m/s
South to 2 m/s South.
The type of acceleration
occurring is…
If the question is correct--Bonus!!!!! (100pts)
What is negative
acceleration or
deceleration?
Game Board
Describe speed and
velocity and state
the difference
between the two.
What is speed is the
distance divided by
time, while velocity is
speed in a direction?
Game Board
Make your wager
Find a runner’s
acceleration if his initial
rate was 2 m/s, his final
rate was 6m/s and this
occurred over 2 seconds.
