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??

What is a force?

Learning target: I will be able to describe what causes motion in terms of forces.

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 …. Measuring in Newton's

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 =

0 N

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.

SpeedThe rate at which an object moves

is it’s speed.

Learning target… I will be able to make measurements to calculate the speed of moving objects.

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?

# OF PEOPLE

Speed m

/s

We usually calculate average

speed.

Because speed changes from 1

second to the other.

Learning target: I will be able to describe the concept of speed

when linked to motion.

Learning target: I will be able to describe the concept of speed when linked to motion.

Graphing Speed

Learning target: I will be able to identify different types of

motion on a graph.

Velocity

This is the speed of an object in a direction.

Learning target: I will be able to apply the concept of velocity to motion.

Velocity changes as

the speed or the direction

changes.

What is the net/resultant velocity?

67 knots North 26 knots South

Resultant/net velocity

Learning target: I can apply the concept of velocity to motion.

Final Velocity = Distance ÷Time

Learning target: I will be able to apply the concept of acceleration when describing motion.

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 graph.

Balloon Cars due Next

Week!

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 gravity.

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 different rates.

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 = EndTerminal 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.

What we think Earth looks like……

What earth actually looks like….

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

Momentum car lab….Bottom of first page(lab) Calculate Car 1 momentum

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

Learning target: I can identify the factors that affect an objects momentum.

Learning target: I will be able to identify situations that

show Newton's laws of motion.

Newton cart lab

How can you make theCup 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.
