Physics 30 - May 3

Today in class we talked about the lab that students did yesterday on horizontal projectile motion.  The reports for this lab are due on Wednesday.  There is a set of data in the course notes link under the Unit 4 folder if students were absent yesterday.  We started to look at universal gravitation today and how to some of the intricacies of using the law of universal gravitation.  This was all covered on slides 13-18.  On Monday we will look at gravitation circular motion.
