Simple Pendulum Mathew Chell and Ryan Vaisler Trinity Western University, Physics 111 Lab 3 29 October 2009 We determined the relationship between mass, length, and amplitude of swing of four pendulum spheres, and measured and compared the value of g attained experimentally to the accepted value for g . We used a photogate timer to measure the period of the pendulum spheres. We saw that period ( T ) of the pendulum spheres, the time for one complete oscillation, differed in each of the four pendulum spheres. This observation did not support the theory that mass (m) has

Unformatted text preview: no effect on period of a swinging bob. It was experimentally confirmed that a direct relationship existed between amplitude ( L g ) and period of the simple pendulum when varying angular displacements were used. We found the experimental value for g to be 9.87m/ s 2 ± 0.770 m/ s 2 . This value is acceptable within experimental error to the accepted value of 9.8m/ s 2 . The assumption that air resistance was not a factor in the experiment was a source of error with a low magnitude of effect on the values attained experimentally....

    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.
