Graphing Review
Distinguish the motion of an object by its position, direction of
motion, speed, and acceleration and represent resulting data in
graphic form in order to make a prediction. (2c)
Keys to Reading Graphs:
1. What are the labels on the axes?
2. What type of graph it is?
3. How is the line changing and
what does this mean?
Distinguish the motion of an object by its position, direction of
motion, speed, and acceleration and represent resulting data in
graphic form in order to make a prediction. (2c)
Graphing Practice Activity
We
will be working in pairs, that
means two people!
As the graphs are passed, go to
that number on your worksheet
and answer each question.
Your pair will have two minutes with
each graph.
Distinguish the motion of an object by its position, direction of
motion, speed, and acceleration and represent resulting data in
graphic form in order to make a prediction. (2c)
What type of graph is this?
Position v. time
How is the object’s position
changing?
It is moving further away.
Predict position at t = 5
seconds.
17 m
Displacement (m)
Is velocity constant, why or why
not?
Velocity is not constant
because its displacement is
changing a different amount
each second.

Newton’s Laws Review
Recognize Newton’s Three Laws of Motion and identify situations
that illustrate each law (e.g., inertia, acceleration, action,
reaction forces). (2f)
Keys to Newton’s Laws:
1. Objects keep doing what they’re
doing unless an outside force acts =
First Law
2. Force = mass x acceleration =
Second Law
3. For every action there is an equal
and opposite reaction = Third Law
Recognize Newton’s Three Laws of Motion and identify situations
that illustrate each law (e.g., inertia, acceleration, action,
reaction forces). (2f)
Newton’s Laws Practice:
1. An object that weighs 25 kg pushed with a force of
m
100 N will accelerate at 4 2 =
s
Newton’s Second Law
2. A jet engine pushes air with 10,000 N of force
backward. The air pushes the jet with 10,000 N of
force forward =

3. A ball rolling across a field will slow down and stop
because of friction =

does move in #4 =
the truck has less inertia than the road.
