None whatsoever. Gravity is determined by the mass and the inverse square of your distance from it. It is not changed by movement. However, under relativistic velocities the mass increases. ..

Centrifugal force lowers the force of gravity at the equator by a very tiny amount. Satellites would remain in orbit if they undergo the same change of velocity as the Earth because relative to the planet they will still be in motion. They would only fall to the ground if they lost their orbital motion with respect to the Earth.

Then the earth should fall on the sun. The gravity of earth will increase as there will be no centrifugal force. So the artificial satellites which are revolving round the earth will fall on earth.

The gravity will not change however the gravity at pole and equipter will become same.
