An object in orbit is in what is known as "free-fall". The best way to understand this is to realise that the object has 2 motions: down, and sideways.
An object 1000 miles high in orbit will fall down towards the centre of the earth exactly 1000 miles. BUT, in the time it takes it to fall that 1000 miles, it moves EXACTLY 1000 miles sideways, so it is still exactly 1000 miles above the earth. It then falls exactly 1000 miles towards the centre of the earth, but in that time, moves another 1000 miles sideways, so it's STILL 1000 miles above the earth.
Now, change that 1000 miles down, for 10 miles, or 1 mile, or 1 inch, AND, change the 1000 miles sideways for 10 miles, 1 mile, 1 inch.
The concept of a stable orbit is that for each unit the object moves DOWN, it moves sideways far enough that it is still exactly the same height above the centre of what it is orbiting.
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
Here we will use the following formula velocity of the satellite v = 2πr/T here r is the radius of the circular path travelled by the satellite = 42250 km and T is the time period = 24 hrs. here, the distance travelled by the satellite in 24 hrs would be the circumference of the circular path of radius 42050 . so, v = (2 X 3.14 X 42050) / 24 = 264074 / 24 :)
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.
A satellite revolves around a planet. Planets revolve around a sun.
A satellite small enough to be treated as a point particle. Can earth's gravity exert a torque on a satellite about the earth's center? Torque causes an object to rotate around a specific point. Torque = force * perpendicular distance and Torque = moment of Inertia * angular acceleration. When a satellite is launched, it is forced up to a specific distance from the earth's center and accelerated to a specific velocity parallel to the surface of the earth. The satellite continues moving in circular orbit. The force which causes the satellite to move in a circular path is the gravitational force caused by the mass of the earth, mass of the satellite, and distance from the center of mass of the earth to the center of mass of the satellite. This force causes the direction of the velocity to rotate so it is always tangent to the circle. This force produces the torque which makes causes the satellite to rotate so the direction of its velocity is always perpendicular to the direction of the gravitational force.
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
circular velocity
A satellite is an object which orbits a larger body. For example, the Moon orbits the Earth, and the Earth orbits the Sun. The Moon is a satellite of the Earth and the Earth is a Satellite of the Sun.
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.

Uniform circular motion is commonly observed in everyday situations such as a car moving around a roundabout or a satellite orbiting around Earth. It is also used in various engineering applications, including the design of amusement park rides, centrifuges in laboratories, and the operation of flywheels in mechanical systems. Understanding the principles of uniform circular motion is essential in fields such as physics, engineering, and astronomy.

Satellites operate through the use of gravity because the force of gravity on the satellite results in circular motion around the earth or any other celestial body, and if that force was too big it would cause the satellite to come crashing down and if it were too small the satellite would just go flying off into space
the velocity will be velocity divided by square root of 2
NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)
'Which of the following?' need some details to be given.
