then use the most suitable formula to find the error in the function. Target precision is a value set before the experiment. This number is a percentage and will let you know how much experimental error is acceptable. In this experiment, the target precision was 0.5%. There are a lot of errors that could be responsible for a result that is less accurate than it is meant to be. Random intrinsic error was encountered in trying to get the pendulum to swing in a single plane. There was also a random error of measurement in measuring the length of the string.

There was also a random error in starting the stopwatch and the pendulum bob at the same time. There was also random measurement error in measuring the radius of the bob. There was friction between the string and the wooden support. Conclusion The experiment was successful as the values fell within the acceptable experimental error .This experiment was short and easy. The calculations were more tedious. The data sheet also had to be completed in pencil as at the end of the experiment when a correction was about to be made, the Excel software became frozen. The errors in the experiment were taken into consideration in evaluating the experimental result and the result was compare to a theoretical value.

    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.
