Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
What is the force that makes satellites orbit at the same height around the earth?
Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.
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.
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.
What is the space orbital?
A space orbital refers to the path that an object, such as a satellite or a planet, follows as it moves around a celestial body due to gravitational forces. It is characterized by its shape, size, and orientation, which can be circular, elliptical, parabolic, or hyperbolic. The specific parameters of an orbital, including its altitude and inclination, determine the object's behavior and function in space exploration or communication. Understanding orbital mechanics is essential for satellite deployment, space missions, and planetary motion.
Why artificial satellite goes around the earth in a perfect circular orbit with constant speed?
An artificial satellite travels in a circular orbit around the Earth due to the balance between gravitational force and its inertia. The gravitational pull from the Earth acts as the centripetal force, keeping the satellite in orbit. If the satellite moves at a constant speed, it maintains a stable trajectory, ensuring that the gravitational force is equal to the required centripetal force. This results in a perfect circular orbit, with no change in speed or altitude as long as external forces, such as atmospheric drag, are negligible.
The curved path that a satellite follows is called what?
The curved path that a satellite follows is called an orbit. This trajectory is influenced by the gravitational pull of the body it is orbiting, such as a planet or moon. Orbits can be circular or elliptical, depending on the satellite's speed and altitude.
Why can a satellite move around the earth in a circular orbit at a constant height?
A satellite can move around the Earth in a circular orbit at a constant height due to the balance between gravitational force and its centripetal force. The gravitational pull of the Earth provides the necessary force to keep the satellite in orbit, while the satellite's velocity ensures it moves forward, creating a continuous circular path. This balance allows the satellite to maintain a stable altitude without falling to Earth or drifting away into space.
Can satellites at different heights have equal velocities?
Yes, satellites at different heights can have equal velocities if they are in circular orbits with the same period. In this case, the satellite at a higher altitude will have a slower velocity than the satellite at a lower altitude, but their velocities will be equal at any given point in their orbits.
How much work is done on a satelite in circular orbit about earth?
In a circular orbit, a satellite is in free fall and moves with a constant speed, which means that the gravitational force acting on it provides the necessary centripetal force for its circular motion. Since the gravitational force is always perpendicular to the satellite's displacement, the work done on the satellite by gravity is zero. Therefore, no net work is done on a satellite in a stable circular orbit around the Earth.
What is the direction of the centripetal force acting on a satellite that is in uniform circular motion around Earth?
The centripetal force acting on a satellite in uniform circular motion around Earth is directed towards the center of Earth. This force is necessary to keep the satellite moving in a circular path instead of following a straight line.
Does a circular orbit satellite accelerate towards earth?
Yes.
How much work is done on a satellite in a circular orbit about Earth?
The work done on a satellite in a circular orbit around Earth is zero because the gravitational force acting on the satellite is perpendicular to the direction of motion, so no work is done to maintain the orbit.
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
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 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.
