pdf2: 7,9,9 Got to graphical interpretation of ${\vec {A}}+{\vec {B}}+{\vec {C}}+{\vec {D}}={\vec {R}}$ on https://cnx.org/contents/Ax2o07Ul@16.4:S9i77L2i@12/3-2-Vector-Addition-and-Subtraction-Graphical-Methods Also, students don't seem to have pdf3 a02 1Dkinem definitions. I might assign that for homework with the understanding that low test scores are OK?

The class explored the non-commutivity of rotations using one die. Facing a page with the usual xy coordinate system, rotation A wa about the positive x-asis by 90 degrees by the RH rule. B was about the negative x axis.

We finished the chapter 3 slides. For an extreme example of the efficiency of notation, see https://www.pitt.edu/~jdnorton/Goodies/Zurich_Notebook/

Define "unity" to be 1 facing the user and 2 on top (with the die placed on a table in front of the user.

• AB results in 5 in front 3 on top.
• BA results in 3 in front an 1 on top.

obviously AB≠BA

Monday and Wednesday: October 21 & 23 We will have another Monday/Wednesday test pair where there is no penalty for flunking the test on Monday, and some sort of vague reward for not needing to take the test on Wednesday. The quiz and answers can be found at:

• ${\vec {p}}=m{\vec {v}}$ is momentum, where m is mass and ${\vec {v}}$ is velocity. The net momemtum is conserved if all forces between a system of particles are internal (i.e., come equal and opposite pairs):
• $\sum {\vec {p}}_{f}=\sum {\vec {p}}_{i}$.
• ${\bar {F}}\Delta t=\Delta p$ is the impulse, or change in momentum associated with a brief force acting over a time interval $\Delta t$. (Strictly speaking, ${\bar {F}}$ is a time-averaged force defined by integrating over the time interval.)
