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.

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.

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.

Is the sun earths satellite?

NO!!!! The Earth's satellite is the Moon. The Sun is the Earth's main star. It can be thought that the Earth is a satellite planet to the Sun.

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.


Is there force in space?

No; gravity will continue acting on your body. If there was no force acting on your body while in space (let's say an orbiting satellite), the satellite would fly out of Earth's orbit and just wander off forever, but that doesn't happen - so gravity has to be acting on the satellite and your body as well!
