Abstract :
Every celestial bodies including our Earth having their own gravity field which causing the attractive force towards the object near them. By assuming that the Earth is symmetrical sphere, the strength of the gravity field at any point on the surface of Earth should be proportional to the mass of the planet and inversely proportional to the square root of two of the distance from the center of the planet. The strength of gravitational force can be equalized with the acceleration of any mass in the influence of gravity and the value on the Earth surface, denoted as g, is approximated with standard average value g = 9.8 m/s2. Experiment conducted during two different solar eclipses, Total Solar Eclipse 2009 and Annular Solar Eclipse 2010. For 2009 experiment, the increment from pre-eclipse to the totality is about 18.92%. For the first and second set of experiment in 2010, showing the percentage increase of gravity acceleration from pre-eclipse to the annularity is about 7.51% and 8.59% respectively. This difference in gravity acceleration may cause chicken egg able to stand during the maximum phase of eclipses.
