1. Seating Chart
2. discussed AP Syllabus 2021
3 . discuss the nature of the class...overview...full course description
4. discussed T.L. Hanna Physics website
5. join Remind for text reminders ( text 81010 with message @f84e4k )
6. students enroll in MasteringPhysics ... here are instructions.
7. students enroll in AP Classroom...here is a tutorial video.
Here is the join code for the mechanics section: 42637K
Here is the join code for the E and M section: AKMWAM
8. students enroll in UT Quest
9. discussed Google Classroom if up and running
10. install Graphical Analysis 4 from Chrome Store
Wednesday 9/9/2020
0. Unit 1 Notes
1. Textbook pickup time 10:30 am.
2. discussed linearization with some possible functional relationships:
a. no mathematical relationship
b. linear
c. top-opening (with numerical example using Graphical Analysis 4 on Chromebooks)
d. side opening
e. inverse
3. Class Demo for Dune Buggy Lab...used Graphical Analysis 4 to graph data
4. discussed the data analysis of the dune buggy lab ... developed for the following observations:
a. linear relationship between position and time
b. intercept units were tiles
c. intercept meaning was starting position or initial position
d. slope units were tiles/sec
e. slope meaning was velocity (the graphical interpretation of speed became "steepness" of slope).
5. started discussing velocity vs. time graphs for CV motion:
graph is a "no-relationship" horizontal graph
area bounded by function and the horizontal time axis on a v vs. t graph represents displacement
6. Today's recording(s):

0. Unit 1 Notes
1. discussed velocity vs. time graphs for CV motion:
graph is a "no-relationship" horizontal graph
area bounded by function and the horizontal time axis on a v vs. t graph represents displacement
2. discussed additional CV representations (x vs. t, v vs. t, motion maps)
3. discussed what the intersection the lines representing two cars, one going in a positive direction and one going in a negative direction, means ... movie of event here and did an example with robots with different speeds
4. referenced Experimental Design and Graphical Analysis of Data
5 discussed Calculus Reading and Assignment #1 (limit)...students completed Calc HW 1 handed out in class
Friday 9/11/2020
0. Unit 1 Notes
discussed Calculus Reading and Assignment #2 (the derivative)
a. watched this excellent video on using Desmos to learn the derivative
b. students work on Calculus HW 2 handed out in class over weekend (just the first page using the definition of the derivative)
3. Today's livestream can be joined here. Today's recording.
Monday 9/14/2020
0. Unit 1 Notes
discussed Calculus Reading and Assignment #2 (the derivative)...short-cut rules...also discussed solutions to page 1
students work on Calculus HW 2( handed out in class Friday). Tonight's hw involves short cut rules for derivatives
3. Day 1 of Kinematic Robots (finish up). The idea of the slope of the "secant' line on a position vs. time graph representing average velocity is developed
4. class investigation using photogates and the car on the ramp: TGAMM
(a) the relationship between instantaneous position and clock reading
(b) the relationship between instantaneous velocity and clock reading
5. Here are some generalizations and conclusions based upon the class discussion of the graphs of the car on the ramp:
a) x vs. t graphs: always curvy...intercept still means initial position and slope still means velocity...steepness of slope still means speed
b) v vs. t graphs: always linear, meaning that the slopes were always constant...defined slope to mean the acceleration after analyzing the units implying that a=(delta v)/(delta t)...identified the intercept as being the initial velocity ... area under v vs. t graphs still means displacement
