There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
The equal, mutual forces of gravity between
the satellite and the Earth do.

NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)
Yes. They accelerate (change the direction of their movement) towards Earth, and this may be labelled as "falling".Yes.

The earth is six times more massive than the moon. That keeps the moon in orbit around it, just as the mass of the sun keeps the earth in orbit around it.
Gravity keeps trees from floating about.

Repelling Force of Gravity
The mutual gravitational attraction between the satellite's mass and the earth's mass. Short answer: The force of gravity.
the gravitational force of earth keeps the satellite(better write artificial satellite)in orbit.
You mean 'keeps in the orbit of the sun? Gravitational force of attraction keeps the earth going around the sun.
No force orbits around the Earth. Forces do not orbit. The force that keeps material objects in orbit around the Earth is the mutual force of gravity between the Earth and the object.
The revolutionary movement of the natural satellite such as moon around the earth makes it stable in its orbit. This is similar to the stay of earth around the sun. Scientifically speaking the gravitational force of attraction between the earth and moon becomes the necessary centripetal force to keep it stay in its orbit. This centripetal force will be along the line joining the moon and the earth. This centripetal will be balanced by the centrifugal which acts away from the earth. This centrifugal force comes into the scene due to the inertia of direction.

Gravity.
The mutual attractive force of gravity keeps the Earth in its orbit around the Sun.
A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket. Satellites in orbit around Earth continuously fall toward Earth, but because Earth is curved they travel around it.
Gravitational force keeps the earth in orbit around the sun. The theory of gravity was originally proposed by Sir Isaac Newton.
