7.7A: Contrast situations where work is done with different amounts of
force to situations where no work is done such as moving a box with a
ramp and without a ramp, or standing still.
7.7C: Demonstrate and illustrate forces that affect motion in everyday life,
such as emergence of seedlings, turgor pressure, and geotropism.

Net Force:
Example:
LT 1: I can explain that forces are always acting on
objects, whether the objects are moving or are at
rest.
Describe what the forces must be like if two teams are
playing tug-of-war and the rope is not moving.
LT 2: I can explain real world examples of balanced and
unbalanced forces and their effect on the motion of
objects.
During a game of tug-of-war the team on the right is
beating the team on the left. Describe the forces on the
rope.
LT 3: I can demonstrate and calculate how
unbalanced forces change the speed or direction of
an object’s motion.
If this object started at rest – which direction would it
move according to this diagram?
LT 4: I can label and diagram the forces acting on an
object and calculate the net force and direction of the
object.
One student pushes a box with 10 N to the right.
Another student on the other side pulls in the same
direction with 5 N. Finish the force diagram and
calculate the Net Force.

LT 5: I can explain the differences between speed,
velocity, and acceleration and give examples of each.
1. What does velocity have that speed does not
have?
2. Changing speed is one example of
acceleration. What else could change for an
example of acceleration?
LT 6: I can recognize real-world examples of speed,
velocity, and acceleration.
Next to each example write if it’s for Speed, Velocity, or
Acceleration.

LT 7&8: I can investigate and describe applications of
Newton’s law of inertia, law of force and acceleration
(F=ma), and law of action/ reaction.
Next to each example write which law applies:
 A small car takes a short time to stop but a
large train takes miles to stop.
____________
 A rocket fires down but the rocket goes
up. ___________
 A car crashes and stops but the driver
continues to move forward through the
windshield ___________
LT9: I can compute speed and acceleration of moving
objects using the equation from Newton’s 2nd law.
A toy car has a mass of 50 kg. A child pushes on the car
with a force of 100 N. At what rate will the car
accelerate? (Please be sure your answer has a unit of
measurement with it)
How does the mass of a body at rest affect its tendency to remain at rest?
How does the force required to move an object change with mass?
How does the force acting on an object affect its tendency to remain at rest?
How do Newton’s Laws of Motion affect everyday situations?
