HW 6 SNAFU

I accidentally made the HW due at noon today instead of midnight ... stupid am and pm. As a result, I have just extended the deadline until noon tomorrow in case you need some more time.

Monday's lab

Tomorrow, we'll do a lab on force. I hope to have the procedure posted in an hour or so, I'm afraid I'm a little behind. To make up for not having allowed much time to read it, I will go over the gist of it at the end of class tomorrow.

[Update: I had the labs out of order. We'll do friction on Wednesday, and a different lab on force on Monday.]

Tomorrow's reading

For tomorrow, we'll cover the mathematical aspects of motion in 1D, and just start on 2D motion. The former will cover essentially all of Ch. 2, the latter sections 3.1 and 3.2 of Ch. 3.

I made one small mistake today when we were talking about the graphs at the very end. The plots I was analyzing should have been position versus time, not velocity versus time. The slope at any given point on the position graph is the instantaneous velocity. If we plot velocity verus time, the slope at any given point is the instantaneous acceleration.

As a result, we'll start off tomorrow morning by discussing graphical analysis of motion again, just so you see it correctly, and then move on to the mathematical analysis of motion.

And, one last thing: be sure to read the lab procedure and statistics introduction before tomorrow's lab. Things will go a lot smoother & more quickly if you've read it ahead of time ...
