Question

If the force of gravity vanishes, what will happen to objects on the earth?

Answer 1

All objects will move tangentially outward of earth due to rotation of the earth but absence of centripetal force (gravity).

Answer 2

Gravitation, or gravity, is the natural phenomenon by which physical bodiesappear to attract each other with a force proportional to theirmasses. It is most commonly experienced as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. From a cosmological perspective, gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence ofplanets, stars, galaxies and most of the macroscopic objects in theuniverse. It is responsible for keeping the Earth and the other planets in theirorbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena observed on Earth and throughout the universe.
