If you missed tonight's class, you missed a pre-test called the "Force concept inventory." It is not a great representation of the tests for the class, but I do appreciate students taking it seriously. Later in the semester, there will be an identical post-test and results will be compared - presumably to see what kind of effect the class has on answering those types of questions. Again, this course is NOT just about that test - far from it.
To make it worth your while - to ensure that you are here for the post-test - I am offering 2 points on the final exam for those students who take BOTH tests. If you missed this evening's class, you can take the pre-test again before class this Tuesday evening at 6:30 or so. Most students finished it in 20 minutes or so.
Any questions, let me know.
Thanks, and happy weekend (and Labor Day) to you.
