Balloon car learning target:
Using the scientific method, I can
demonstrate Newton’s 3 laws of
motion by creating a working
balloon car.
Balloon car learning target:
Using Newton’s 3 laws of motion.
I can explain my balloon cars
performance.
Balloon car summative
1. Think about… if you had never
blown the balloon would your car
ever move?
Did the car travel forever…. Why
not?
2. Was your car heavy or light…did you
need more or less force to move it?
Did it move fast? Did your balloon
give enough force?
3. If the air goes back the car goes
forward right??
Learning target: I will be able to describe what
causes motion in terms of forces.
What is a force?
It is a push or a
pull
All forces
have a size
and a
direction.
Forces can
change the
direction,
speed or size
of an object
What do we
measure
forces in?
Newton's (N)
After Sir Isaac
Newton.
Learning target…. I will be able to tell the
difference between mass and weight.
Formative lab ….
Newton's
Measuring in
Forces can be
balanced or
unbalanced
Learning target….. I will be able to describe what causes
motion in terms of forces.
Balanced
Forces
• The net force is the
difference between the 2.
100N – 100N
=
0N
So nothing moves.
There is no motion.
Unbalanced
forces
The net force is this time is 75
N
100N – 25N
=
75N
There forces are
unbalanced so
there is motion.
Learning target….. I can describe what causes motion in terms of
forces.
Net / Resultant force
What is
motion?
Motion is
when
something
moves.
We can only
detect motion
when we link it to
something that is
not moving.
Learning target… I will be able to make measurements to
calculate the speed of moving
objects.
Speed
The rate at which an
object moves is it’s
speed.
Now gather all the data from the class
only relating to their speed running….
Now produce a scatter plot with line
of best fit..
What is the best fit speed of the
class?
Speed m/s
#
OF PEOPLE
We usually calculate
average speed.
Because speed
changes from 1
second to the other.

graph.
What affects the
speed of a car?

Learning target: I will be able to apply the concept of velocity to motion.
Velocity
This is the speed of an
object in a direction.
Velocity changes
as the speed or
the direction
changes.
What is the net/resultant velocity?
Resultant/net velocity
67 knots North
26 knots South
Learning target: I can apply the concept of velocity to motion.
Learning target: I will be able to apply the concept of acceleration when
describing motion.
Final Velocity
=
Distance ÷Time
Learning target: I will be able to apply the concept of acceleration when
describing motion.
In math you would call it negative
acceleration.
Negative acceleration/deceleration
Learning target: I will be able to identify different types of motion on a gra

Learning target: I will be able to describe Newton's law of universal
gravity.
Earth
Learning target: I can describe Newton's law of universal
LEARNING TARGET: I can tell the difference between mass and weight.
Learning target: I will be able to explain why things fall to earth
at
You must test the feather and flat paper
Learning target: I will be able to explain why things fall to earth at
different rates.
Learning target: I can explain why things fall to earth at
different rates.
Learning target: I will be able to explain what friction is.
Learning target: I will be able to correctly identify the four main types of
friction.
Learning target: I will be able to explain what friction is.
How might Friction affect
the performance of your
balloon car?
Learning target: I will be able to explain why things fall to earth at
different rates.
Learning target: I can explain what terminal velocity is.
Terminal = End
Terminal velocity is the fastest an object can
travel.
Learning target: I can explain freefall in relation to forces.
Learning target: I will be able to describe the separate forces that
cause projectile motion.
Learning target: I can correctly identify the forces that cause projectile
motion.

an objects momentum.
Learning target: I will be able to identify the factors that affect
an objects momentum.

affect an objects
Learning target: I will be able to identify situations that
show Newton's laws of motion.

How can you make the
Cup with 3 pennies travel
As far as the cup with
no pennies?
Learning Target:
I will be able to explain how force, mass and
acceleration are related to each other.
F(w) =M x A
M= F(w) / A
A = F(w) / M
F (w)
M A
Learning target: I can identify situations that show
Newton's laws of motion.
