6. Bell Ringer
How do ice hockey players keep moving across the ice at high speeds for long times while seeming to expend no effort?
Why does a soccer ball continue to roll across the field after it has been kicked?
Why does the soccer ball eventually stop moving?

7. Learning Targets
On your Bell Ringer Sheet, write the following: I can describe inertia. I can relate inertia to mass.

8. Newton’s first law Continue notes where left off yesterday
An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an outside force.

9. What does this mean?
Basically, an object will “keep doing what it was doing” unless acted on by an unbalanced force.
If the object was sitting still, it will remain stationary (at rest). If it was moving at a constant velocity, it will keep moving.
It takes force to change the motion of an object.
Force: a push or pull

10. Then why don’t things move forever?
There’s almost always a force acting on a object.
A book sliding across a table slows down and stops because of the force of friction.
If you throw a ball upwards it will eventually slow down and fall because of the force of gravity.
In outer space, away from gravity and any sources of friction, a rocket ship launched with a certain speed and direction would keep going in that same direction and at that same speed forever.

11. Seat belt lab In notebook title new section “Seat Belt Lab”
Question – What will happen to your passenger when the car hits the wall? Will the speed affect what your passenger looks like after the crash?
Question – How will the seatbelt affect the outcome of your passenger?
Hypothesis (one for each question) –
Independent variable –
Dependent variable -

12. Seat belt lab
Answer the questions on the handout in your notebook.

13. Reading
Newton’s First Law and Inertia reading

14. Law of Inertia A different name for the same thing!
Inertia: the tendency of an object to resist changes in its state of motion
The First Law states that all objects have inertia.
The more mass an object has, the more inertia it has (and the harder it is to change its motion).
What’s an example of this?
