1. Study for your quiz (anything dealing with kinematics is fair game). You may want to review this website if you still don't understand calculus-based kinematics: http://physics.info/kinematics-calculus/ and http://physics.info/kinematics-calculus/practice.shtml

*in general, http://physics.info is another text-source we'll be relying on so... get used to seeing this come up more often! You may just want to review what they have to say about kinematics (Chapter 1.1)

**Practice Problem: 
An object moves along the x-axis according to the function x(t) = 5 – 2t + 3t^2 – 0.5t^3, where t is time measured in seconds and x is position measured in meters. (a) Determine expressions for this object’s velocity and acceleration as functions of time. (b) For the interval of time t = 0 to t = 4.0 s determine: (b) average acceleration, (c) maximum rate of acceleration, (d) average velocity, (e) maximum speed, and (f) maximum distance from the origin.

Helpful pages for derivatives: http://www.mathsisfun.com/calculus/derivatives-introduction.html and http://www.mathsisfun.com/calculus/derivatives-rules.html

2. Read (only, no annotations needed) Chapter 1.2 Dynamics from that same website (above).

3. Read and annotate Chapter 4 from Openstax textbook.

4. Complete Openstax p.162 #31, p.163 #32, 33, 41, 42

Unit 1 - Assignment#3 - Gravitation!

1. Make sure to finish all the problems I assigned to you previously... (we went over them in class...) include all units! I want to collect it and give you content grades!

2. Finish your lab... including a procedure and a conclusion for each lab! LOOK AT SCIENCE 4... (Talk specifically about what types of errors - random or systematic - were in the lab and how you would improve the lab!)
  • All science outcomes are in the "ABOUT" section of Google Classroom.
3. Play around with this pHet on Newton's Law of Gravitation: http://phet.colorado.edu/en/simulation/gravity-force-lab, create your own lab in your lab notebooks!
  • If you need a refresher... this is a good resource: https://www.khanacademy.org/science/physics/newton-gravitation
4. Watch and take notes on this video (30 minutes): https://www.youtube.com/watch?v=6a0-Ry-fufA

Unit 1 - Assignment#2 - 2D Kinematics

1. read and annotate chapter 3 from openstax.
2. read and annotate chapter 3 from ck-12 textbook.
3. openstax textbook p.123 #25

Unit 1 - Assignment#1 - 1D Kinematics

posted Sep 3, 2014, 8:07 PM by ms.jun@fmhsnyc.org

On Thursday (Sept. 11th), we will be doing a lab/seminar on finding the initial velocity of a popper toy. To prepare for this lab, I would like for you to...
  1. read and annotate chapters 1-2 from openstax textbook in BLUE INK on loose-leaf.
  2. read and annotate chapters 1-2 from ck-12 textbook in BLACK INK on loose-leaf.
  3. openstax textbook p.83 #43 (this problem is a HUGE hint on what our lab is going to be about!)

*You may notice that both textbooks say similar things about kinematics... so if you have taken detailed notes first from openstax book and would like to just add a few new or emphasize on important stuff from the ck-12 book, just do that in a different colored ink. You don't have to take the same notes twice. So, an advice would be to fold the page in half hot-dog style and pick one of the two books to start taking notes from. Then, just add notes on the other side corresponding to that concept. Let me know if you have any clarifying questions.
