Lab for Mon 8 June

Tomorrow, you'll do a lab on momentum.

Quiz 4

Quiz 4 and an answer key can be found here.

Exam 1 is Thursday at 8am during the lab period

As you may be aware, exam 1 is Thursday during our usual lab time (8am) in our usual lab classroom (GAL 203). While this is a 2hr50min hour class period, I am designing it to be more like a 1.5 hour exam. You will have the full 2hr50min if you need it, but if you finish sooner (like I hope) you can just leave early.

Here are the sections from the textbook covered

• 1D motion (2.3-2.9)
• 2D motion (4.2-7)
• Force & motion (5.2-9, 6.5; friction noticeably absent)

There will be 6 problems in total, of which you must complete 4. Problems meaning no multiple choice, show your work. If you do more than 4, I will grade them all and use the best 4 (but try to get 4 done well first). There will be a formula sheet (much like this) provided with all the basic formulas and any numerical constants you will need, and you can 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.

There will be heavy partial credit on the exam, so show all your work and be as clear as possible about what you are trying to do. You won't have to follow the homework template, but it won't hurt either.

Good things to study? Old homework and exams, and the homework problems I've given you so far. The exam questions will be easier than the homework I've given you, so don't worry too much. Doing the example problems in the book, or the odd numbered end of chapter problems is also good (so you can see the answer when you're done).

Now, 8am is a tough time for an exam if you're not a morning person. I'd advise first to get some sleep the night before, and second to exchange contact info with some of your classmates so you can wake each other up as need be. If you do oversleep for the exam, showing up late is fine. You won't get extra time on the exam, but you'll be allowed to take the exam up until 10:50. If, for example, you don't show up until 9am, you've still got 1hr50min. Better to show up late than not at all.

Quiz 2, 3 solutions

You can find solutions for the first three quizzes here.

Solutions for the first week's homework

Substantially complete solutions to the first week's homework are now ready, and can be found here. It is obviously particularly important that you read the solutions for problems you weren't totally confident about, but it is probably still worth skimming the solutions even for the problems you had no trouble with, just to be sure.

Also: brevity is not a strong suit. I tried to be explicit about exactly what I was doing at every step (with the exception of skipping a few algebra steps here and there that you should be able to fill in), and as a result the solutions are fairly long. There is no TL;DR version I can come up with that does a passable job of explaining things.

Lab for W 3 June

Tomorrow, we'll do a lab on friction forces.

Week 2 homework

Week 2's homework is out. First problems due tomorrow, we'll go over some of them in class.
