IB Physics HL - Year 1 (2019-2020)

8/16

8/20

  • 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

8/22

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

8/26

8/28

  • derive the kinematic (or suvat) equations
  • practice using the kinematic equations
  • homework - solve sample IB test questions on motion graphs

8/30

  • 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

9/4

  • 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)
  • homework - do test corrections on a separate sheet of paper; also, complete the worksheet from class

9/6

  • 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
  • check your Interpolations and Extrapolations homework against the key

9/10

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

9/12

  • begin formal lab investigation of free fall acceleration (enter data here)
  • the general Lab Report Format

9/16

  • "linearize" the free fall data in Logger Pro; add trend lines
  • the lab report will be due 9/20 (at 11:59 pm) through turnitin.com
  • practice solving motion problems
  • homework - complete the motion problems (answer key)

9/18

  • introduce a new way to represent vectors - 3Blue1Brown video
  • model 2D projectile motion
  • homework - read pp. 39-43 in your textbook

9/20

  • test over 1D motion (with a focus on the kinematic equations, but including a few graph-related questions) - postponed until 9/24
  • continue modeling of projectiles launched at an angle
  • study this animation of a launched projectile
  • the lab report is due tonight through turnitin.com
  • homework - solve these kinematics problems (answer key); review for the test

9/24

  • test over kinematics (no 2D projectiles)
