1. Bellringer….8-27
How does force affect motion? Do all forces affect motion?
Make sure to answer both questions! 

2. Review
What is a force?
What two things are needed to describe a force?
What are the two types of forces?
What effect does force have on motion?

3. Newton’s Laws of Motion

4. Today’s Goals…
I can describe how forces affect motion.

5. Newton’s First Law of Motion
An object will NOT change its motion unless an unbalanced force acts on it
An object at rest remains at rest and an object in motion remains in motion until acted on by an unbalanced force

6. Inertia Newton’s first law is sometimes called the law of inertia
The tendency of an object to resist change in motion
The more mass an object has the greater the inertia
Consider what happens when you are in a car and you turn a curve, how does this illustrate Newton’s first law?

7. Newton’s Laws
Newton’s first law predicts when an object’s motion will change
Newton’s second law predicts what that change in motion will be

8. Changes in Force and Mass
any change in motion (speed) depends on how much force is applied and how much mass is involved
Think about the activity!
How did you increase the book’s speed?
How did you decrease the book’s speed?

9. Changes in Force and Mass
You can increase acceleration by increasing force or decreasing mass
You can decrease acceleration by decreasing force or increasing mass

10. Illustrating Newton’s Law
You and your partner are going to come up with a way to illustrate Newton’s first and second law of motion.
