Name a physical and chemical
property of wood.
Physical: Floats on water, Rough
texture, breaks when bent
Chemical: ability to burn
If you mix to solutions together and
notice a temperature change, has a
chemical reaction occurred?
Yes
When a chemical reaction has
occurred has a new substance been
created?
Yes
Chemical change means a new
substance formed. Physical change
means there has been no change to
the original substance. (Torn paper is
still paper)

When an object is acted on by an
unbalanced force it will always….
A.
B.
C.
D.
Accelerate
Continue at the same speed

Come to a stop
Accelerate
When a man jumps from a boat to a
dock, the boat begins to move in the
opposite direction of the dock. Which
of Newton’s laws is this an example
of?
Newton’s 3rd Law
For every action, there is an equal
and opposite reaction
The boats moves in the opposite
direction with an equal amount force
that has been applied to it from the
jump.
What is the difference between
Distance and Displacement?
Displacement includes direction
Associated with velocity
When a bowl is pushed across a
table, what force eventually stops
the bowl from moving?
Friction
If a projectile flies north 387 meters in
5.8 seconds, what is its velocity?
66.72 m/s North
If a 4500 kg car is traveling westward
with an acceleration of 35.2 m/s2,
what is the force acting on it?
158,400 N
F= m x a
A dock worker needs to stop a crate
containing 3 boxes of goods that is
rolling across a manual conveyer belt.
One box has a mass of 8.5kg and is
accelerating at .75m/s2. How much
force will he need to apply to the crate
in order to stop it?
19.125 N
• The crate contains 3 boxes so you must
multiply the mass of one box by 3 to get the
mass of the entire crate. (3 x 8.5 kg= 25.5 kg)
• Use the formula f=m x a
• F= 25.5kg x 0.75 m/s2= 19.125N
When you are riding in a car and you
must come to a complete stop
abruptly, why does you body continue
to move forward?
Because your body contains
inertia.
An object in motion tends to stay in
motion unless acted on by on
unbalanced force.
Which of Newton’s laws deals with a
relationship between mass and
force?
Newton’s Second Law
F=m x a

How do volcanoes form at mid-ocean
ridges?
As the tectonic plate moves apart,
magma from the Earth’s mantle
comes to the surface, building ridges
and volcanoes

• Speed and velocity have stayed constant
• Speed has changed but velocity stayed
constant
• Speed stayed constant but velocity changed
Speed stayed constant but
velocity changed

pushed with a force of 5,000N will it
continue to move at 10m/s? How will
its speed be affected?
No, it will move faster.
The speed of the rocket will
increase.
