The velocity of the satellite along with the earths gravitational pull work together to keep a satellite from either flying out into space or burning up in the atmosphere. They have to launch a satellite at a precise speed to make sure that the speed at which the satellite falls to earth matches the earth's curvature. The speed is 8000 meters a second.
Gravity
Gravity keeps things together here on Earth. It keeps the Earth together in the first place, and it keeps us on Earth. It keeps the Earth in orbit around the Sun, and it keeps the Moon in orbit around Earth.
earth's gravity
The sun's gravitational pull keeps the earth in orbit around it.
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
Gravity.
The mutual attractive force of gravity keeps the Earth in its orbit around the Sun.
Gravity and Inertia keeps the earth in orbit
The balance between the inertia of the Moon and the gravitational pull keeps the moon in orbit with Earth.
Gravitational force keeps the earth in orbit around the sun. The theory of gravity was originally proposed by Sir Isaac Newton.
