What direction of the velocity causes a circular orbit?
The velocity in a circular orbit changes all the time. The acceleration is towards the center.
Is torque produce in satellite due to gravity?
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 in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
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.
Are satellites an example of acceleration as it orbits around the earth?
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating?
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.
Where is the Chinese rocket launch facility?
It is at Jiuquan Satellite Launch Center, Taiyuan Satellite Launch Center, Xichang Satellite Launch Center, and Jingyu.
What is the direction of acceleretion of a body in circular motion?
-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.
When was Jiuquan Satellite Launch Center created?
Jiuquan Satellite Launch Center was created in 1958.
What is the effect on the orbital velocity of the sattelite if its orbital radius is doubled?
You can calculate this with Kepler's Third Law. "The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit." This is valid for other orbiting objects; in this case you can replace "planet" with "satellite". Just assume, for simplicity, that the satellite orbits Earth in a circular orbit - in this case, the "semi-major axis" is equal to the distance from Earth's center. For your calculations, remember also that if the radius is doubled, the total distance the satellite travels is also doubled.
What is the difference between escape velocity and orbital velocity?
Escape velocity is the velocity that an object needs in order to reach infinite distance, wherein the force will equal to zero. Orbital velocity is the velocity of an object so it can stay in orbit.
What is the acceleration of an object moving in circular path at constant velocity?
Centrepital Acceleration.Normal acceleration known as centripetal acceleration in case of circular motion with uniform speedAn object in circular motion experiences continuous change in its direction ofmotion, and may or may not experience changes in its speed. Either changeconstitutes acceleration.The force that keeps an object in circular motion is often directed towardthe center of the circle. It's then known as "centripetal" force, and producescentripetal acceleration.
