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

• 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
