Motion 10 points In physical science, a push
or pull is classified as a ______.
What is a Force
4
Motion 20 points A bike rider averaged a pace
of 30 km/hr in his last race, if the race was 45
km how long did it take him to finish?
What is 1.5 hours
5
Motion 30 points A car hits traffic on the
highway and slams on the breaks going from 80
km/hr to 20 km/hr in 10 seconds, what was the
cars acceleration?
What is -6km/hr/s
6
Motion 40 points As a ice skater glides along
at 32 m/s all forces acting on her become
balanced, what happens to her motion?
What is it remains the same (she keeps going at
32 m/s)
7
Motion 50 Points A horse gallops 75 meters
back to the barn in 5 seconds, what is his
velocity?
What is 15 m/s towards the barn.
8
Force 10 points What must be true in order for
forces to be unbalanced? (there are 2 parts to
this answer think about net force and type
affect on motion)
What is a net force greater than 0 and there must
be a change in motion
9
Force 20 points A penny drops to earth
reaching its terminal velocity of about 36 m/s as
air resistance and gravity become balanced, what
happens to the motion of the penny once this
occurs?
What is it stays the same, a constant downward
fall at 36 m/s.
10
Forces 30 points
Calculate the net forces acting on the
wheelchair. Are they balanced or unbalanced?
 
170 N
48 N
What is 122 N left, forces are unbalanced.
11
Forces 40 points
What is the net force and direction for the
object below?
What is 3 N left.
12
Forces 50 points
Name the letter of all of the examples of
balanced forces below. A. a baby pushed in a
stroller on a sidewalk at a rate of 6 m/sB. a
child running down a path and then halting at a
swing setC. a ball rolling down a hillD. a
projector hanging from the ceiling (like the one
in the room )
What is A and D.
13
Friction 10 points
How will the motion of a ball rolling on the
ground change if the ball encounters a frictional
force?   
What is the ball will slow down.
14
Friction 20 points Many skiers put wax on the
bottom of their skis to help them move faster
down the hill, why does this help?
What is the wax fills in some of the jagged edges
and cracks which reduces the amount of friction.
15
Friction - 30 points You need to move a dresser
so you push on it as hard as you can but it will
not budge! What type of friction is responsible
for this?
What is static friction.
16
Friction - 40 points When moving something
heavy sometimes it is easier to put it on wheels,
why is this? Be specific and reference the types
of friction involved!
What is rolling friction is less than sliding
friction because less surface area is in contact.
17
Friction 50 points Sand is often put down on
icy roads, why is this?
What is sand increases the roughness of the
surface which increases the amount of friction.
18
Gravity 10 points A penny falls off the top of
the empire state building, after 6 seconds how
fast is the penny moving? (assuming minimal air
resistance)
What is 58.8 m/s.
19
Gravity 20 points Where could you go that
there would be no force of gravity acting upon
you?
What is nowhere. Even in outer space there is
gravity, it is significantly reduced compared to
when you are on earth but it is still present.
20
Gravity 30 points Draw a picture that
represents why a ball thrown here on earth will
eventually fall to the ground. Remember to label
all forces and motions involved!
Horizontal motion or inertia
Actual path of the ball
gravity
21
Gravity 40 points Name two ways to reduce the
force of gravity between the two object below
What is decrease the mass or increase the
distance between the two.
22
Gravity 50 points Explain the forces and
motions involved in keeping the earth in orbit
around the sun.
What is the earth has inertia carrying it in a
straight line which the gravity of the sun
slightly curves causing the earth to orbit the
sun in a circular path. .
23
Graphing Motion 10 points Describe the motion
of the object as graphed below
What is the object is moving at a constant speed.
24
Graphing Motion 20 points What happened from
time 2s to time 5s on the graph below?
Distance (m)
What is the object stopped for some reason.
25
Motion Graphs 30 points How fast is the object
moving from time 3s to time 11s?
What 1 m/s.
26
Motion Graphs 40 Points What is the
acceleration from time 16s to 21s on the graph
below?
What is 1m/s/s.
27
Motion Graphs 50 points How fast is the object
moving from time 11s to time 16s?
What is the object is not moving.
