Final Exam Review
WARM-UP: (10min)
1. Define "triage"
2. The final will contain problems from all of CH 1-4. Review the "study skills" section at the end of each chapter, and then answer the following:
A. What are the topics in CH1?
B. CH2?
C. CH3?
D. CH4?
3. Considering the material in those chapters, which topics do you need to focus on the most?
CLASSWORK:
1. Independent Review Time (30min)
Practice problems and solutions are on the Day 40 page
2. Review Games
- Vocab and Theory Kahoot!
- Choose a chapter (1-4) and make a Kahoot based on that chapter.
- you can make T/F questions, vocab questions, or short problems to solve
- Use in class, and use at home to review.
- When creating your Kahoot, use the hashtag, #BCCHSphysics
- Your Kahoot needs 5 Questions and Answers
- When you finish, share it with me, jgalexander is my user name.
- Extra Credit if it's good :-)
HOMEWORK:
Prep for the test
1pg single side sheet of notes for the exam
Bring a pencil, eraser, calculator (not your phone), water, brain.
Goals: SWBAT...
1. Recognize that the vertical and horizontal motions of a projectile are independent.
2. Relate the height, time in the air, and initial vertical velocity of a projectile using its vertical motion, and then determine the range using the horizontal motion.
WARM-UP
Question:
Can you describe a projectile’s motion in both the horizontal and the vertical directions?
Procedure:
1. Take out a safe-to-toss object from your pocket/backpack/purse. A coin, pen cap, eraser, hat, ring, are all good objects. No knives...
2. Gently toss the object from your right hand to your left hand, and then back again. You should be observing the flight path of the object, and thinking about it's components of velocity.
Data:
3. Sketch your objects motion through the air.
4. Draw two motion diagrams: one for the ball’s horizontal motion and one for its vertical motion. Of course, you remember that a motion diagram is uses velocity arrows to compare instantaneous velocity at specific time intervals, right? Sure you do :-) Here's a sample, in case you forgot to review these over winter break:

Analysis:
5. How does the vertical motion change as time passes? Does it increase, decrease, or stay the same?
6. How does the horizontal motion change as time passes? Does it increase, decrease, or stay the same?
CLASSWORK: (for each CW activity, think about which goal you are meeting. Also, tell me how the activity helps you achieve that goal)
1. Read CH6, pg 147.
What is the term for "an object shot through the air"?
What is the term for "an objects path through space"?
2. Watch The Science of the NFL
http://science360.gov/obj/tkn-video/fc729ef0-22ee-4f61-bb2a-b6c07685fb02/science-nfl-football-projectile-motion-parabolas
Individually, list five (5) projectile motion facts and/or questions from the video:
Example: "Once a punter kicks a football, it becomes what we call a projectile, and it follows a path called a parabolic arc"
3. Solve: pg 164 33(skip d), 34, 35
4. "Over the Edge" Quick Lab (I'll do this Thurs as a quick demo)
A. Predict which ball will hit the floor first when you roll one battery horizontally off the surface of your table, and simultaneously let the other battery free-fall from the edge.
B. Explain your prediction.
C. Test your predictions. Obtain two AA batteries, and two stopwatches (phones). Take five trials. Record data in a simple chart.
Analyze and Conclude
D. Does the horizontal velocity of the battery affect its vertical velocity?
5. Moved to HW
HOMEWORK:
Due Thursday: Read 148-149. Pay close attention to the "Problem Solving Strategies" section.
Solve pg 150: 1, 2, 3; pg 164: 40, 41, 43
