What Do You Think The Earth Looks Like?

Well, you would feel that the earth is flat, but it is actually round! A lot of scientists have been into space and taken images for the same. Then, why don’t we fall off the edge? Why does the wishing star we see seem like it falls on the ground? The answer to this is simple. It is due to the earth’s gravitational force. Earth attracts everything towards its centre. That is why we do not fall off.

Up and Down On The Earth

Do you think the people in Argentina stand upside down? And the star they see on the ground? NO! They are also standing just like you do and see the star up in the sky just like us! Up and down are just relative with respect to the shape of the earth and space.

The Effect of the Gravitational Pull

It is the gravitational force that keeps everything on the ground. We are all attracted towards the ground because of this force. In the space, there is no gravitational pull.

Can You Think Why Was Sunita’s Hair Standing?

We know that on earth, our hair remains in downwards portion due to earth’s gravitational force. But in space, there is no such gravitational force. That is why Sunita’s hair was standing.

This gravitational force is also the reason why water flows downwards on any slope or on mountains. Scientist Newton discovered gravitational pull when he was busy thinking and making a wish from the wishing star when an apple fell from a tree over him! He imagined why the apple would fell down instead of moving up. This led to the discovery of gravitational pull.
