A Great Work-Energy Question

February 27, 2012 Leave a comment

I know we haven’t really gotten into energy yet, but I don’t want to forget about this question.

Check it out (from Reddit-AskScience):

How small would a moon have to be so that you could could jump and escape?

Even though it appears people have posted an answer, this would be an excellent screencast for a reassessment.


A bunch of videos

Here are some videos with force and motion. These aren’t all for the Matter and Interactions textbook, so sometimes the notation might be slightly different. They should still be useful.

Screencast reminders

February 17, 2012 Leave a comment

If you submit a screencast for a reassessment, remember the following:

  • Send me a link, not a video.  You have to post the video somewhere (youtube, jing, vimeo, whatever…)
  • Clearly indicate which standard you are reassessing (like 2.2 or whatever).
  • You need to pick a NEW problem to do.  If you change the numbers on a problem that we did in class, this is not a new problem.
  • You are supposed to get two other people to look at your screencast before you send it to me.  I am just going to trust you will do this.  If it becomes an obvious problem, I will have to somehow check this.  Please don’t make me check it.
  • Don’t forget, you can resubmit stuff if your first reassessment is within 2 weeks of the in-class assessment.
  • Just so you know, I am going to do evaluations on Fridays.  If you send me something on Sunday, I won’t look at it until Friday.  It doesn’t mean I don’t care.

The next assessment in class

February 16, 2012 Leave a comment

I was a little bit wrong.  I said that the next in-class assessment would be on chapter 5.  Well, we haven’t done chapter 4 yet.  So, on Feb 28 I will give an assessment on both chapter 4 and chapter 5.  It will probably be a little bit longer than the previous assessments.
