October 19

Today in class we looked at a picture of an accelerometer and discussed the uses for it. I thought it was really interesting that they are used in the iphone to rotate the screen.
Then, we talked about the lab report that we are doing as a class. Tonight, everyone will write an entry that will help us come closer to finishing this project. We are including and introduction, apparatus, information about how mass, surface type, surface area, and velocity affect the blocks, modern studies, and a conclusion.

We went over our homework 4C. It involved adding and subtracting vectors.

For the last few minutes of class, we started graphical vector constructions. We found the change in position and the velocity from one point to the next. It is a better approximation if you find the change in position and velocity between the two points.

Homework for tonight is to write an entry for the lab report and homework 4D if you have time.
tomorrow's scribe is...Mary Elizabeth :)
