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.
