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?

Speed m

/s

We usually calculate average

speed.

Because speed changes from 1

second to the other.

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.

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.
