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

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 1file 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

  • begin formal lab investigation of free fall acceleration
  • the general Lab Report Format

9/13

  • calculate lab uncertainties
  • the lab report will be due Wed 9/18 (at 11:59 pm) through turnitin.com
  • homework - you should get started on the lab report

9/17

  • graph the free fall data -- linearize the graph
  • homework - complete your lab report; the free fall calculations are due 9/23

9/19

  • quiz over free fall  postponed until Monday
  • review free fall calculations
  • discuss relative motion
  • homework - complete free fall calculations (handout)

9/23

  • quiz over free fall
  • introduction to vectors
  • homework - read pp. 39-43 in your textbook

9/25

  • model 2D projectiles
