FORCES
Fill in the graphic
organizer
as you read
through the
notes. Then
glue to page
106.

2. A force…
• is a push or pull.
• can be described by size and direction.
• Forces are expressed in newtons (N).
• The more newtons, the greater the force.
(Discuss with your ipad partner examples of forces.)

3. • Keep in mind, just because a force is
being exerted by one object doesn’t mean
that motion will occur. (“Exerted” means
“applied”.)
• Sitting in a chair is an example of force
being exerted without motion.
(Can you think of another example of a force being exerted
without motion occurring?)

4. Balanced
forces
(Copy onto g.o.)
•Equal forces acting on an
object in opposite directions.
Can be a push or a pull.
•Will not change an object’s
motion.
•The net force is zero.
•Example—Two evenly
matched teams in a tug of
war contest.

5. Unbalanced
forces--
• When a net force greater than zero is
acting on an object, the forces are
unbalanced.
• Unbalanced forces will cause an object to
accelerate.
• (Review your notes and discuss with your
ipad partner what “accelerate” means.)

6. Net forces--
• all of the forces acting on an object.
• When a net force greater than zero is
acting on an object, the forces are
unbalanced.
• Unbalanced forces will cause an object to
accelerate.
(Review your notes and discuss with your ipad partner
what “accelerate” means.)

7. Draw this
diagram on
page 106 and
label it.

8. The arrows show forces acting on
a block.
What is the net force on the block
and in what direction would the
object move?
A.100 N to the right
B.100 N to the left
C.100 N upward
D.150 N upward
