5. Newton’s third law of motion
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.

6. What does it mean? All forces act in pairs!
Newton’s third law of motion means that
All forces act in pairs!
Newton’s third law only addresses forces. The way that the force pairs interact affects the motion of objects.

7. Force pairs do not act on the same object.
The ACTION FORCE is the swimmer’s hands and feet pushing on the water.
The REACTION FORCE is the water pushing on the swimmer’s body.
The reaction force moves the swimmer forward

8. Another example The ACTION FORCE is the book pushing on the table.
The REACTION FORCE is the table pushing on the book.

9. The ACTION FORCE is the person pushing on the wall.
The REACTION FORCE is the wall pushing on the person.
Why is the result different?

10. Here is another example of a force pair.

11. Here is another example of a force pair.

12. What are the action and reaction forces?

13. What are the action and reaction forces?

11.4 Momentum
Objective: I can calculate momentum using the formula
p = mv
Homework:
11.4 RSG
Please Have on Desk:
ISN, textbook, pencil

15. Momentum Notes
11.4

16. Objects in motion have momentum
A moving object has momentum.
Momentum is a measure of mass in motion.
Momentum = mass x velocity
p = mv

17. Objects in motion have momentum
Complete the momentum math triangle.

18. Momentum can be transferred from one object to another
A collision is two objects in close contact exchange energy and momentum.
Examples: bumper cars, bowling ball and pins, pool balls, hockey stick and puck….

19. Momentum is conserved
The principle of conservation of momentum states that the total momentum of a system of objects does not change, as long as there are no outside forces acting on that system.

20. Momentum is conserved There are two types of collisions.
Elastic: the objects separate after the collision (bounce off each other)
Inelastic: the objects stick together after the collision

21. Wednesday, March 8th
Entry Task Describe an example of each of Newton’s laws from the game.
Schedule:
Finish Newton’s Law foldable
Objective: I can creatively apply Newton’s laws of motion to a theme
Homework:
Foldable due tomorrow
Please have on desk:
Textbook, ISN

22. Newton's Laws Foldable
You will create a foldable that explains and illustrates Newton’s three laws of motion.
Your foldable must have an overall theme. Ex: a type of sport, nature activity, hobby…

23. Newton's Laws Foldable
1. Determine your theme. Complete the front of your foldable.
2. For each of Newton’s laws of motion,
- write the law at the top of the page
draw, label, and color a drawing that illustrates this law. Your drawing must follow the theme you chose
explain HOW your drawing illustrates that particular law of motion

24. Drawings are original neat and colored; clearly match explanation
9-10
6-8
1-5
Explanation clearly shows understanding of law; written law included
Explanation shows knowledge of law, but not understanding; written law included
Explanation show limited knowledge of law; written law not included
Drawings are original neat and colored; clearly match explanation
Drawings are not original, but neat and colored; do not clearly match explanation
Drawings are not original, messy and not colored; no match to explanation
