1. Honors Physics 13 Oct 2009 Review of motion in one dimension – please have your review sheet and questions (in compositionn books) Preview motion in 2-D and vectors Homework: Read p 81-85

2. Honors Physics 14 Oct 2009 Warm-up: What is the difference between a scalar and a vector? (Hint: last night’s reading contains the answer) Today: Free-fall team challenge (or the linear motion review) Homework: Section review p 85 (1-5)

3. Honors Physics 15 Oct 2009 Warm-up: Name at least 3 things we have learned about that must be represented by vector quantities. Any complete team challenges? HW check Lesson: Vectors # 1 – definitions and basic concepts Lab work due tomorrow: Include answers to questions, data table, and two graphs – with explanations

4. Vectors 1 Another question first: A dog walks 3 km south, then turns and walks 4 km west. What is it’s displacement? (the answer is not 7) We can use vector analysis to answer this question Vectors are quantities with magnitude and direction Vectors can be represented by lines with lengths proportional to their values – lets look at this….

5. Vector Terminology Components (short sides of a right triangle) Resultants (hypotenuse of a right triangle)

6. Honors Physics 16 Oct 2009 First today: Projectile motion video demo Brief discussion of vector analysis of projectiles Independent assignment time – you should be turning in one assignment each week to keep on track for at least 10 by the end of the quarter Free-fall labs due today. Please turn them in by the end of class.
