미국에서 제출한 일반물리학 `진동`부분 실험보고서
- Understanding the relationship between the periods of oscillation and a diversity of mass through the vertical spring motion, and the relationship between the period of oscillation and various length through the simple pendulum.
- Understanding how to use an oscilloscope and analyze results.
With the same way used in the part A, I except two data which are max. and min. Then, I determine g=10.46m/s2 through averaging the remains. In fact, the acceleration of gravity is about 9.8m/s2. I think there are some reasons why there is difference between the values from the experiment and real value. First, counting with eyes has an error because man`s eye and response is not accurate as machines. Also, there might be air resistance and mistakes to take data.
* Analysis of Part C
My oscilloscope had problems. It didn`t show the value on the screen, which I expected. Only POSITION switch was working. It was possible to do procedure ①~⑦. And I could suppose the value from each procedure.
