What does the work-energy theorem say about the speed of a satellite in circular orbit?

Not very much, I would say. There is no work being done in this situation so there's no change in kinetic energy. So the satellite's speed remains constant.
But we already knew the speed was constant. Perhaps I'm missing something.

The work-energy theorem states that the work done on an object is equal to its change in kinetic energy. In the case of a satellite in circular orbit, the work done on the satellite is zero because no external forces are acting on it. Therefore, the speed of the satellite in circular orbit remains constant.

What are the forces acting on a satellite that is in a circular orbit about the Earth at an altitude at which air resistance is negligible?
In a circular orbit with negligible air resistance, the main forces acting on a satellite are the gravitational force pulling it towards the Earth's center, and the centripetal force keeping it in its circular path. These two forces are balanced, allowing the satellite to maintain a stable orbit.
Why do Satellites travel in a circular path?
Satellites orbit the Earth or other bodies due to a careful balance of their velocity and the gravitational attraction of the body. Essentially gravity pulls them down but their velocity moves then out (Newton's Fist Law of Motion) at the same rate. They keep missing the body they orbit.The path is not necessarily circular since the gravity over the Earth varies with the density of the ground below the satellite. They are also satisfied to be in an elliptical orbit (closer at some times than others). The moon is a good example of a satellite in an almost circular elliptical orbit. comets have wildly elliptical orbits.
Where is the acceleration of a satellite directed?
Straight toward the center of mass of whatever body it's orbiting. If the orbit happens to be circular, then that's the center of the circle.
What is the name for a non circular orbit?
An elliptical orbit is a non-circular orbit where the orbiting object follows an elongated path around another object.
What is the orbit of our solar system?
circular
Does a circular orbit satellite accelerate towards earth?
Yes.
What is a satellite orbit?
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
What is the circular path the shuttle makes in space?
low-orbit (satellite)
Does Archimedes principle holds a good for a satellite moving in a circular orbit?
no

How does the direction of motion of a satellite in circular orbit compare with the curve of earth's surface?
The direction of motion of a satellite in a circular orbit is perpendicular to the curved surface of the Earth. This means that the satellite moves parallel to the surface at a constant distance rather than following the curve of the Earth.
The velocity required to keed a satellite in orbit around the Earth is called?
circular velocity
What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
The orbit is a circle. When the velocity of the satellite is perpendicular to the force of gravity, it means the gravitational force only provides the centripetal force needed for circular motion.
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
What is an example of Circular acceleration?
a satellite in orbit; it is moving at constant speed but is accelerating outward in circular acceleration, balanced by gravity acceleration (centripetal force).
A satellite of mass 5500 kg orbits the Earth in a circular orbit of radius of 9.3 106 m this is above the Earth's atmosphereThe mass of the Earth is 6.0 1024 kg?
The gravitational force acting on the satellite is provided by the gravitational force between the satellite and the Earth, and is directed towards the center of the Earth. The gravitational force is responsible for causing the satellite to move in a circular path around the Earth. The centripetal force required to keep the satellite in its circular orbit is provided by the gravitational force between the satellite and the Earth.
How high should be the satellite to be a geostationary?
In order to appear motionless in the sky, the satellite must be in an orbit that is -- circular -- over the equator -- 22,400 miles above the surface
