It turns out that the weight gets lighter near the equator compared to the extreme region of the earth

One of the most famous apple in the world, "Newton's apple" has been handed down that it was discovered "GravitationThere is a regional difference in the power of the region, and the result that the gravity becomes weaker as it goes to the highland in the equatorial region was announced.

Here's How Gravity Varies Across Australia And Why You Weigh More In Tasmania Than Queensland | Business Insider Australia

This survey was conducted by a joint research team of Australia and Germany, and as a result of a combination of data from the satellite and a small terrain model, it was recognized that the gravity has a regional difference of 0.7% at the maximum . This is a result that is more than 40% higher than the traditional forecast.


It is the north pole where the gravity becomes strongest, its gravitational acceleration is 9.83 meters per second per second. On the contrary, the most gravitational weakness is due to Peru's highest peak in the tropicsHuascaranAt the summit (altitude of about 6700 m), the gravitational acceleration shows 9.76 m per second per second. If people weighing 100 kg ride on the same scale in these two places, the weight will be lightly displayed 700 grams at the top of Huascaran.

Christian Hirt of the research team, Mr. Christian Hirt of the University of Curtin, Australia, said that "Because there is a considerable difference in the earth's surface and the equator has an elliptical shape with the longest diameter, this phenomenon We will also explain the difference in gravity depending on the density of the substance buried in the ground. "


The research team has released the findings for free and wants us to be useful for geological survey and exploration of underground resources.

Although "weight" will be lighter, there is no change in "mass".
