Warm-up
What does a vector represent?
Row leaders – please make sure your people have a ruler for today.
Upcoming important dates
Monday, 9/12 – homework quiz
Tuesday, 9/13 – last day to re-quiz over the summer assignment
Friday, 9/16 – unit quiz and review due
Monday, 9/19 – unit test

3. Homework Quiz Take out your challenging a claim homework.
Three minutes to complete.

4. Re-calibrating

5. What is a vector A line representing a magnitude
14 Newtons
5 meters
Speed of 6 m/s
A arrow representing a direction
14 Newtons of tension force to the right (think of the string from our lab on Thursday.
Traveling 5 meters north
Traveling at a velocity of 6 m/s west

6. Evaluating magnitude and direction
Complete the practice questions from section one.

7. Check your answers

8. Connecting to the lab
How does the practice you completed connect to the lab from last week?

9. What is a resultant Vector sum of two or more vectors.
It is the result of adding two or more vectors together (note: vectors are drawn tip to tail)
Example
Diagram source:

10. Methods of determining the magnitude of the resultant.
Resultant (R)
Graphically
Pythagorean theorem

11. Head to tail practice

12. Practice – adding vectors graphically

13. Adding vectors using Pythagorean theorem
Review CNs

14. Resolving vectors using Pythagorean theorem
Practice

15. Revisiting FBDs

16. Pulling it all together

17. Homework Review your notes from today and practice from today.
Complete static equilibrium practice

18. Cool Down
How would you choose a method to determine the resultant of two or more vectors?
Can you do all of the ‘I can statements’? If no what actions are you going to take to make sure you can?
