Tomorrow's lab

Tomorrow's lab will be on simple harmonic motion.

Lab grades are not right

Somehow, all the lab grades got mixed up during upload. I'll fix it over the weekend, but if your lab grade isn't showing up correctly now, this is probably why.

Current grades

I've posted all the grades I have so far on Blackboard. I could spend a whole lecture explaining how Blackboard is a massive pile of fail, but it does work in the end, to some degree, so I'll not complain. It gets the job done, it is reasonably secure, but I can offer no further compliments.

Anyway. Here is what we have.

* Quizzes 1-4 are graded. I dropped the lowest quiz in calculating your overall average, as the quiz average is quite low. I don't have quiz 5 grades yet, but I suspect an upturn.
* Lab report 1 is there, I don't have lab report 2 yet.
* Homework problems 1-8 (through 8 June) are included, I've not finished grading later problems. Nothing dropped in calculating your overall average.
* Exam 1 is included, but not exam 2 yet.
* Your average before exam 2, including: quizzes 1-4 (dropping 1), homework problems 1-8, lab 1, and exam 1 is included as a separate column.

The main thing you should do now is check for discrepancies and bring them to my attention as soon as possible. If, for example, I'm missing a HW you're sure you turned in, we should figure this out quickly. Make sure your scores one Blackboard match what you've been handed back in general.

Exam 1 and its solution are available

Here you go.

Exam 2

Exam 2 is this coming Thursday 11 June during our usual lab time (8am) in our usual lab classroom (GAL 203). The exam format will be much like last time, and I again expect you will not need the entire class period. Recall that the lab period is outlandishly early in the morning, and it can't be helped.

Here are the sections from the textbook covered

• Work & KE (7.3-7)
• Potential energy (9.2-5, 7-8)
• Momentum (9.4-10; notably excluding center of mass)

There will be 5 problems in total, of which you must complete 4. There will be a formula sheet (much like this, but without the rotation stuff) providing all the basic formulas and any numerical constants you will need. You can also bring in one sheet of 8.5x11in paper of your own with notes, etc. What you put on the one sheet you bring in is entirely up to you, and you can use the front & back of the sheet.

Basically, same drill as last week, different chapters. 

this week's homework

Find it here. First problems due tomorrow (10 June).

Lab for tomorrow 10 June

Tomorrow we'll do two short procedures. One on the coefficient of restitution (how much height does a ball lose after bouncing), one is on statistical analysis demonstrated by card counting.

Both are relatively short (in spite of the longish introduction on the first one), and you should have plenty of time to finish both.

For the lab report this week, that means you'll have 3 labs in total. You still only need to write a report on one of them, include the raw data for the other two as an appendix for your report.

(Also: there will be a short quiz on momentum.)
