Why do we not fall from the earth?

Gravity is the force of the Earth that attracts every object towards itself. From our perspective this force always act to downwards. For a long time people did not believe that  the Earth is round because then the people  'underneath' the sphere would have actually fallen down. In 1687, the physicist, Issac Newton, proved that the force of gravity always act towards the center of the Earth. On the Earth, the force of gravitation always acts 'downwards ' irrespective of Eskimos in the Arctic region, people in Europe or inhabitance of Australia.

What is the external structure of the earth?

It has been known for more than 2000 years that the earth is round, but we were able to actually see this much later only when we flew into space. The knowledge why we do not fall off from the Earth is much more recent. Today, we know that the Earth is also surrounded by an air cover called atmosphere.

Did you know that...


-more than 2200 years ago, the Greek discovered that the earth is round? They even calculated an almost accurate circumference of the Earth!!

-the earth is not a perfect globe? The circumference at the equator is 40,077 km, whereas measured over the poles it is 68 km less.

-atmosphere'  is a Greek word which means  'ball of vapour'?
