#Goals:
SWBAT...
1. ...correctly answer 80% of the review questions
What can you do to raise your grade?
complete the lab
complete the FBD art assignment for late credit
retake quizzes
complete this week's assignments for full credit
study for the final
take full advantage of this week of review/study
Warm-Up
Consider the trajectory diagram shown below for a projectile thrown at an angle to the horizontal. The vector arrows represent the horizontal and vertical components of the projectile's velocity. Several points in the trajectory are labeled with a letter. Use the trajectory diagram to answer the next several questions. (Consider air resistance to be negligible.)
32. At which point(s), if any, are there no forces acting upon the object? List all that apply.
33. At which point(s), if any, are the forces acting upon the object balanced? List all that apply.
34. At which point(s), if any, is there a net force acting upon the object? List all that apply.
35. At which point(s), if any, is the net force acting upon the object directed toward the right? List all that apply.
36. At which point(s), if any, is the net force acting upon the object directed upward? List all that apply.
What can you do to raise your grade?
complete the lab, now late, but late is better than never
complete the FBD art assignment for late credit (I've extended the late credit on this assignment)
complete any assignment which is a week (or less) late
retake quizzes
complete this week's assignments for full credit
study for the final
take full advantage of this week of review/study

HOMEWORK:HOMEWORK:
1. Complete the Review. Due Thursday.
LABS ARE DUE NOW :)
WARM-UP
1. Consider the word, 'void'. What does it mean for a space to be void of matter?
2. A search and rescue worker needs to know the depth of a cave so they can choose the correct length of rope. Which speed should they use to calculate the distance, the speed of Electro-Magnetic waves (aka, speed of light (3x108m/s)) or the speed of sound (343m/s)?
3. If the echo returns to the worker in 1.2 seconds, find the depth of the cave.
CLASSWORK
1. 072A: EM waves & Transparent vs. Opaque - Notes & Practice Questions
Opaque: If an object is opaque, then the vibrations of the electrons in the EM wave are not passed from atom to atom through the bulk of the material. Rather the electrons of atoms on the material's surface vibrate for short periods of time and then reemit the energy as a reflected light wave. Such frequencies of light are said to be reflected.
Transparent: Transparent materials are materials that allow one or more of the frequencies of visible light to be transmitted through them
Is water transparent? Are you sure? Think about the photo of the ocean linked here (LINK) ...what color is missing? (credit to Riley for thinking of this one - GREAT example)

2. Quiz grading
HOMEWORK
1. If you didn't finish your Lab (due today), finish it over the weekend and turn it in for 80% credit monday.
2. Quiz on Monday
3. Periods 1 & 2, we didn't talk about this, but you should think about it: Is water transparent? Are you sure? Think about the photo of the ocean linked here (LINK) ...what color is missing? (credit to Riley for thinking of this one - GREAT example)
