Is a satellite orbiting earth free from earths gravity why or why not?

No, that's why it's orbiting the earth instead of flying off into space.
To it takes a force to change velocity. Changing direction changes velocity, so it requires a constant force to travel in a circle--think of the tension in a string while you twirl a rock attached to the end.
A satellite if falling toward the earth constantly. As a thought experiment, consider dropping a rock to the ground. It falls straight down. If you throw it straight sideways, it travels for some horizontal distance before it hits the ground. A bullet travels further. Now, if you could shoot something fast enough, it would travel so far sideways before it reached the ground, that the ground itself would start curving away underneath it, because the earth is a sphere. If you go fast enough, then you can go so far, that the ground curves away under you at the same rate that you curve in your path as you fall towards the ground. This is basically what a satellite does--it falls around the earth.

What is the largest natural satellite orbiting the earth?
The only natural satellite orbiting Earth is the moon.
A natural satellite orbiting the earth is?
It is the moon.
Is the pull of gravity between the moon and the earth keeps the moon orbiting the earth?
yes, earths gravitational pull is strong enough to pull the moon into orbit around it.
The moon orbiting earth is an example of a what satellite?
A moon is a natural satellite, as opposed to an artificial satellite, which is a man-made object in orbit.
Inward and outward forces when a satellite is orbiting Earth?
GRAVITY!!!!
Does a satellite orbit earth free from earths gravity?
No. Gravity is responsible for all 'orbits'. If there were no other body attracting it, the orbiting object would sail off in a straight line.
Are satellites orbiting earths gravity?
No. They orbit Earth; and the reason they orbit is because of gravity.
What is Name of the largest satellite orbiting earth?
The largest satellite orbiting the Earth is the Moon.
What is the largest natural satellite orbiting the earth?
The only natural satellite orbiting Earth is the moon.
Is the sun earths satellite?
No. The mass of the sun is much larger than the mass of the earth, so the earth is regarded as orbiting around the sun.
What are satellite image?
Photos taken of Earth from an orbiting satellite
What role did a satellite play in the beginning of the space race?
It showed that orbiting the Earth was feasible, a vital step towards escaping Earth's gravity. (I've assumed that you mean a man-made satellite, rather than our Moon, which is also a satellite of the Earth.)
Is it correct to say that satellites fall back to earth falling to earth because they are beyond the pull of earths gravity explain?
That is not English; that is not physics. Generally speaking, the speed of the satellite and gravity cancel each other. As the satellite slows (friction), gravity wins.
How To Use Satellite in a sentence?
I saw a satellite orbiting around earth.
What is the satellite orbiting the earth called?
It is the moon.
A natural satellite orbiting the earth is?
It is the moon.
A satellite is projectile that falls ot of earth rather than into earth?
Satellites are in constant free-fall. This simply means they are constantly being accelerated by earth's gravity. However, an orbiting satellite's lateral motion is sufficient that the acceleration caused by the earth's gravity causes it to continually circle the earth, instead of crashing to the ground.
