Week of 10/9

This week, we only had a few members of Professor Kuo's Physics 1 class visit on Wednesday. Almost everyone who came in asked about question 4 because they were confused on the wording. It was unclear to some of the students why the change in kinetic energy of mass 2 was not equal to the change in potential energy of mass 2 if energy is always conserved. We had to explain that some of the potential energy was converted to kinetic energy for mass 1 even though mass 1 did not lose any potential energy. On Thursday I did not have any students visit for office hours.
