Bishesh Khadka Period 6 (Rest of group besides Brandon Coy were from 5th hour)
Conclusion:
In this lab we analyzed the difference in impulse, work and change in energy between inelastic and elastic collisions. To do this we had a double sided mallet-pendulum strike a cart on a relatively frictionless track at varying heights. We filmed the collisions and used Logger Pro Video analysis to obtain the corresponding data values. When the total energy of a system is held constant, an inelastic collision will have less impulse and take less time than an elastic one, while having a greater average force than an elastic one. 
Reflection:
This lab was slightly tedious. The data acquisition part of this lab was open-ended which was good to a certain extent. It was slightly difficult to extract a concise procedure from the lab manual so it was a bit difficult in that sense. I would suggest for next year a more concise manual page for this lab specifically.
My group I was initially in did not get sufficient data, and so I joined a group from period five. I worked with their data and I sufficiently contributed to data analysis, error analysis and procedure. Working with this already large group was a bit inefficient due to our collaboration occurring on a google docs and a large IM thread. However, it yielded end results that are miles more satisfactory than the results I would have obtained from my initial lack of data.  I enjoyed collaborating with my peers and working together to analyze and discuss the purpose of this lab.
