## Why don’t we fall of the earth?

Gravity always pulls you towards the middle of the object. So for the Earth, which is shaped like a ball, the force of gravity pulls you to the centre from every point on the ground. That’s why, no matter where you stand on the Earth, you always feel like the ground is at the bottom and the sky is up

## Why do we not fly off the earth?

Normally, humans aren’t thrown off the moving Earth because gravity is holding us down. However, because we are rotating with the Earth, a ‘centrifugal force’ pushes us outwards from the centre of the planet. If this centrifugal force were bigger than the force of gravity, then we would be thrown into space.
