Why do we not
fall off from the Earth?
Gravity is the
force of the Earth that attracts every object towards itself. From our
perspective this force always acts 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, a physicist, Isaac Newton, proved
that the force of gravity always acts towards the centre of the Earth. On the
Earth, the force of gravity always acts “downwards”.
