Objectives : The purpose of this lab was for the student to observe a pendulum and explore the operations of it. The student was to take data from a pendulum’s path and use this data to investigate the conservation of mechanical energy laws. Experimental Procedure : For this lab the student needed to measure one cycle of a pendulum. To do this the student needed to measure 20 points in the pendulum’s path. This was done by using a electric inkjet that made a dot every 1/60 th of a second. To start the experiment we placed a piece of paper behind the pendulum so the inkjet had something to print on. Then we pulled the pendulum so it was just a few degrees below horizontal. Then we let the pendulum go. After a few oscillations we started the inkjet at the top of one swing and let it print until it was almost starting a new cycle. Then we took the paper that was printed on and picked a succession of 20 clear points to measure, these points were used in the results. Results : To analyze this information we had to split the data points into intervals. These intervals were from 1-3. 2-4, 3-5 … all the way to 19-20. The height of each interval was determined by the midpoints of the intervals.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
