No. Satellites ARE falling. But they are also moving "sideways", and so quickly that by the time the satellite has fallen to the Earth, the satellite has continued AROUND the Earth, and missed!
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.
Satellites remain in orbit around the Earth due to a balance between the gravitational pull of the Earth and the satellite's velocity. The satellite's forward velocity allows it to continue moving tangentially to the Earth's surface, preventing it from being pulled towards the surface. This balance enables satellites to maintain their orbit without falling back to Earth.
Gravity is caused by mass, so objects with more mass, such as planets and stars, exert a lot of gravity. The earth and everything on it are constantly falling towards the sun because of the sun's immense gravity. ... Because of this sideways momentum, the earth is continually falling towards the sun and missing it.
Gravity.
No! They are in orbit because of earth's gravity. If they were beyond the pull of earth's gravity, they would fly off and never return. Everything that is in orbit around earth is falling towards earth. Their orbital velocity is great enough so that it compensates for the downward pull.When you throw a ball it falls in a curve. Throw it harder and the ball will fall farther away but will still fall along a curve. Throw it as hard as possible and it will still follow a curved path and eventually land. Gravity causes it to fall along a curve. Now imagine throwing a ball SO HARD that it returns to you from the opposite direction. Gravity has been pulling on it causing it to move along a curved path, but its velocity sends it around earth in an orbit.

satellites are not weightless. they actually aren't even floating in space. satellites are constantly falling towards the earth but because of their crazy fast speed they constantly miss the edge of the earth and can continue falling. pretty wild stuff gravity is.

No. They orbit Earth; and the reason they orbit is because of gravity.
they are placed in a carefully calculated orbit around the earth, gravity effecticly stops satellites from deviating from their path, the are all "falling" to earth, but at the distance and speed that they are going, the curvature of the earth cancells out the speed that they are falling. Some larger more expensive satellites are able to self correct via ion engine thrusters, and others designed for short term use in low orbits are equipped with traditional fuel boosters. All satellites will eventually fall to earth as the drag of space and the microscopic differences in the earths gravity field will pull it further into the atmosphere.

1-Apples falling down. 2-Gravity keeps satellites in their orbits around the earth.
because of the gravity
Satellites do not defy gravity they are actually falling all the time. They follow a curving path, however, and when that path matches the curve of the Earth, they are in orbit.
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
Because gravity is holding it in place.
