IB Physics SL (2019-2020)

**8/15**

- Informational Packet /
__Syllabus__ - Syllabus
__Addendum__- Grading - Introduction to class
- Homework - brainstorm a notation for keeping track of how far an object moves AND in which direction it travels, e.g. a man walks 20 meters eastward, then 20 meters northward, then 10 meters westward; can you write this in a way that the sum of these three motions gives you the man's final position?

**8/19**

- discuss briefly the history of modeling motion
- differentiate between average and instantaneous speeds and define constant speed
- determine if a toy car moves with constant speed
- create a scatter plot of the motion of a toy car and discuss the significance of its slope
- Homework - read to p. 11 in the booklet (Physics: An Introduction); do the 6 math questions on p. 10

**8/21**

- define distance, displacement, speed, velocity and acceleration
- "read" position, velocity and acceleration graphs and relate them to one another

**8/23**

- "read" motion graphs (
__worksheets__) __help sheet__for reading motion graphs

**8/27**

- derive the kinematic (or
*suvat*) equations - practice using the kinematic equations
- Homework - solve sample IB test questions on motion graphs; if you have a textbook, read over pp. 27-38 for a review of the material we've covered thus far

**8/29**

- test over motion graphs, with general questions about distance, displacement, speed (average and instantaneous), velocity and acceleration
- Homework - install Logger Pro on your laptop (on a school-issued laptop, install it from the Software Center; on all other laptops, use these
__instructions__); read pp. 27-38 in your textbook

**9/3**

- graph the motion data in this
__spreadsheet__and add trendlines - practice interpreting trendlines and using the extracted (velocity and acceleration) information to interpolate and extrapolate (
__file 1__,__file 2__) - Extra Practice - match motion to graphs with
__this interactive__. - Homework - do test corrections on a separate sheet of paper (just rework the missed problems)

**9/5**

- picture day
- read what Aristotle and Galileo had to say about falling "bodies"
- study how objects fall using a "motion detector" -
__lab instructions__ - homework - finish the lab at home; read (and take notes on) pp. 8-16 in your textbook

**9/9**

- use the kinematic equations for modeling freely falling objects -
__worksheet__ - homework - read about experimental uncertainty (its measurement and propagation in calculations) -
__handout__

____**9/11**
