Tuesday, Oct 7, 2008 - Blocks 1 and 3

Collected Rocket 2 labs.

Students are still not doing well on the graphical addition of vector quizzes and on the analytic addition of vectors (vector worksheet 4).

I went over in detail an example of graphical addition of vectors and did the same example in detail for analytic addition of vectors.

Handed back quizzes and vector worksheet 4. Also handed back CD 3.2

Asked if any questions on Rocket Lab or on the homework problems 17-25

Students did vector worksheet 5 on ijk notation.

Explained set-up for Hit the Bar Lab and went through competitions 1 and 2. Didn't get through competition 3. Left the details for homework - find distance ball falls from max height, time to fall, total time in air, x location.
