DAY 20
Good morning. I'm out of the classroom. Be focused, and help each other when you get stuck. You can do this. :-)
Warm-Up:
The Unit, Newton
In a week, we'll begin exploring forces in earnest, but for now, we're just looking at how projectiles behave. You will, however, see the symbol N and the word "force" quite a bit, so you need to know what those two things mean. Here we go....
1. A Newton is a unit of force, named after Sir Isaac Newton (the apple guy)
2. Force is a ________ or a _________
3. Basic equation of Force is F= __ * ___
4. Therefore, the units of the Newton are (kg)*( / )
5. Review the W/U here: (refresh the page if a link isn't active - I may still be adding things to the page...) LINK
Classwork:
1. (10 min) Review of Day 19: LINK
2. (15min) Notes: Introduction to Vector Components.
Answer the Edpuzzle questions. Check your notes here: http://www.flippingphysics.com/uploads/2/1/1/0/21103672/0052_lecture_notes_-_introduction_to_vector_components.pdf
3. (25 min) Copy pg 124 example problem 2 into your Day 20 Notes.
Watch the review of Day 19, pg 121 problems 1-3 LINK
Then do Practice Problems pg 125 5-7
4. Practice Problems pg 125: 8-10
***I will post some hints to the HW later this evening***
HOMEWORK
pg 125 11-15 plus any of Day 19 and Day 20 Classwork you didn't complete.
If you need help, go see Ms. Lovegren or Mrs. Herring (they both are nice and teach physics)
10/04/16
Goals:
WARM-UP
1. Translation: Use position-time Graph B (here) to draw the corresponding velocity-time graph using the same time scale.
Do the same for Graph H
2.
Homework Questions?
CLASSWORK:
0. Quiz
1. Equations of Position and Velocity with Average Acceleration
2. Walking Through Graphs
3. Practice Problems
- Complete individually. You may consult with groupmates/Mr. A if you need help
- On page 69, complete example problem 4 and practice problem 26.
- Practice using the GUESS method, by neatly writing each set of info.
- Don't forget to use..... UNITS! :-)
- For #4, read the question, and then answer the following:
a. What should the units be in your answer?
b. Which sign (+) or (-) should your answer have?
- The answer to #4 is 89m, #26 is 8.8s. Once you finish solving, ask yourself, "Is this answer realistic?" "Does it make sense given the parameters of the problem?"
3. Complete pg 70 Example Problem #5
4. Individual papers (still), complete pg 71, Practice Problems 30-32
Answers are: 4.3x103m; 27m; 1.16x103m/s2
