Author(s): Peng Song; Si Wu; Meng Zhao; Dongli Zhang

Paper Abstract

The gravity acceleration is an important physics constant, which is measured by the rotating liquid as a university physical experiment. However, the present experimental methods have a bigger amount of experimental error. A modified rotating liquid optics method is presented to measure the gravity acceleration, in which an angle measurement instrument with an accuracy of 0.05 degree is introduced. Laser is used to measure the angles of the highest point and the lowest point of the rotating liquid. Then the gravity acceleration can be calculated. The modified method has more little error and makes the experiment easier and more convenient.
