The gravitational force between Earth and the Sun provides the centripetal force needed to keep Earth in orbit. This force keeps Earth moving in a circular path around the Sun.
Gravataional force is applied by the spinning of the earth.

Gravity
One way to determine the mass of the Earth is to use Newton's law of gravitation and the known period and distance of the Moon. By knowing the orbital period of the Moon around the Earth and its distance from Earth, one can calculate the gravitational force between Earth and the Moon. By equating this gravitational force to the centripetal force needed to keep the Moon in its orbit, one can solve for the mass of the Earth.
The centripetal force holding the earth on its axis will be so great that the gravity keeping the earth and the sun at the same distance will not be enough to keep the Earth close to the sun. We would essentially fly off into the nothingness of space and die.
Gravity..
The sun has all the gravity to keep the planets a certain distance from the sun.
A restraining order, I think
Gravity is a force that pulls objects towards the center of the Earth. This force keeps objects on the Earth's surface by attracting them towards the ground.

Work is the product of (force) x (distance).If, as you allege, the force increased but the work didn't change, thenthe distance must have decreased, by exactly the same factor as theincrease in the force, so that their product is not changed.
