# Thread: Would there be less gravity or different gravity if you were to travel to the center of the earth?

1. I know this may sound like a kind of amateurish question, but its been bothering me for quite a while. I wouldn't think there is gravity at the earths center but I came here to post so I could get a proper answer from people who really know. Thanks

According to Newton's Shell Theorem, gravity would get progressively less until it reaches zero at the gravitational centre. Basically, as you descend, a shell of equal depth to where you are gets cancelled out the whole time. Because of that, if you were inside a giant pingpong ball, you would be weightless at any point within it, no matter how thick the walls were.

Hope that helps

Think about the difference between gravitational force and net gravitational force.

5. Gravity is caused by mass ( in this scenario ).
At the center of the earth, there is equal mass all around you in every direction ( roughly ).
Therefore, you experience an equal gravitational force from all directions around you. Because of this, all these forces cancel out, and you experience a zero net force. At the earth's center you would feel no gravity, even though it is actually there.

6. hmmmm.. ur right
so the ans is - at the centre of the earth u experience zero gravitational force.........
any more queries?

7. u experience zero gravitational force
zero NET gravitational force.
