Test 2 Prep edit
T 2/6/18 edit
Ping pong/air drag?
W 2/7/18 edit
On Tuesday, both groups traded places and wrote group reports on the rolling ping pong ball and on the motion detector. That class chose not to have each group repeat the other's experiments because they felt the inter-group reports were sufficient. Does this lab want to do the same?
Watched Newton's Dark secrets?
R 2/8/18 edit
Ping Pong/Air drag?
F 2/9/18 edit
See Wright_State_University_Lake_Campus/2018-1/Ping_pong_air_drag. Went through calculation.
M 2/12/18 edit
Worked on Test 2: friction and uniform circular motion.

- Exercises in drawing and utilizing free-body diagrams The Physics Teacher 37, 434 (1999); Skip 1 and 2. Write and solve numerical problems for 3-6. Make it a test question, that does not require a drawing (tough writing assignment). Submit the questions electronically to Pilot as individual reports. Submit the solutions (groups OK) on blanck typing paper, with your name(s) along the top inch margin, and "Public Domain" somewhere on the page.

The error (uncertainty) in x has a porportionality with the error in f(x) if f=Ax^n. The error can be calculated by comparing f(x) with f(x+dx). Faster? way: df/f=ndx/x (obtained after algebra)
