Laboratory Report Physics 151 Laboratory Section 14 Thu 07:00 pm to 09:45 pm Instructor: Hamed Sadeghi Student: Payam Farrokhi Laboratory Session #2 Date 09/15/2011 Vector Addition: Graphs, Vector Components, and the structure of Space A) The Abstract The experiment in this session was about conditions of equilibrium. During this session, we also learned about measuring and analyzing vectors that represent forces. B) The Introduction Three forces were applied to a metal ring sitting on the table. The forces were generated by three hanging masses which were attached to the ring via some string. There were some given angles, and we were responsible to find the right masses which would make the ring to be equilibrium. C) The Conclusion By doing the session of lab report, we got to know more about forces and their effects on each other as well as on the system. We were also able to analyze vectors in different situations.
